Summary
Currently, two trends in society are visible. One trend is that conventional breeding increas-
ingly focuses on F1 hybrid breeding and the use of patents. Another trend is that consumers,
in particular organic consumers, value product quality more and more. For organic traders
and farmers this means an alternative approach in breeding becomes more urgent: a
breeding approach that meets economic, societal and nutritional values in a balanced
way. The breeding of open pollinated (OP) varieties has the potential to meet these values,
important for organic consumers. However, the choice of good OP varieties in terms of yield,
storability and uniformity is often limited as the focus in plant breeding has been on F1 hy-
brids for the past 40 years. In organic agriculture, good taste and good nutritional values are
also considered important traits.
So far, breeding has focused on yield and storability. However, some field trials on carrot
and pumpkin suggested there can be a negative relation between storability on the one
hand and taste and quality on the other hand. It implies that varieties with good taste are
more difficult to store than the commonly used varieties by farmers. An important question is
what can be done to improve the storage period of vegetables with good taste and qual-
ity. One option may be to look for varieties that have a good balance in storability, taste
and nutritional value.
To answer these questions fields were conducted for two years with three vegetable crops
(pumpkin, red cabbage and carrots) on two bio-dynamic farms with different soils (clay and
sand). For each of the crops, three open pollinated varieties and two F1-hybrids were com-
pared. On each of the farms the trials were set up with three replications and completely
randomised designs. On both farms, two harvest dates were applied for all three crops.
Sowing, planting and harvesting dates on both farms were chosen as similar as possible.
Apart from general observations on crop growth, the crop traits that were measured for
analysis were yield (fresh and dry matter yield), storability, taste (after harvest, mid storage
and after storage), and nutrient quality (dry matter percentage, Brix and content of eight
minerals). Tasting was conducted at the beginning of the storage period, half-way and to-
wards the end of the storage period. ANOVA and correlations were used to analyse the re-
sults.
Results show that the interactions for yield, storability, taste and quality are complex and
crop specific. One general conclusion is that whereas yields can differ a lot between varie-
ties when calculated in fresh matter, yields are much more similar when calculated in dry
matter. Correlations also suggest negative relationships between yield fresh matter) and
quality (in particular dry matter content). Another general conclusion is that soil quality has a
big effect on storability and taste.

This is in agreement with the growth and differentiation concept. In this research the stora-
bility on clay soil tended to better than on sandy soil. For pumpkin and red cabbage taste
was also better on sandy soil than on clay soil, which is also in agreement with the growth
and differentiation concept. However, carrot from clay soil tended to taste better than from
the sandy soil in this research, which might be explained by the weather conditions of the
two seasons under which the trials ran. At the end of the summer rainfall increased and it
seemed that the carrot crop increased speed of growth.
Time of harvesting seems to have a large effect on the outcomes of the correlations of taste
with many other parameters, for all three crops. When starting up the research, the effect of
harvest moment was an important element of discussion. The results suggests different pat-
terns in the effect on storability, taste quality for each of the crops.
For each of the crops, no general patterns were observed that were applicable to all crop
varieties in terms of change in taste during storage. For pumpkin, varieties grown on sand
tasted generally better than from clay soil. For some varieties, however, taste decreased on
clay soil during storage, whereas not for other varieties. For carrot and red cabbage, the dy-
namics in taste development during storage were more complex.
As a general conclusion it may be argued that it should be possible to breed for crop varie-
ties with a good balance in yield (fresh), dry matter yield, taste and storability. How this bal-
ance should look like exactly for each of the crops is a point of discussion with farmers, trad-
ers and consumers. Presentations of the first results to farmers and consumers at several oc-
casions in 2018 underline the importance of finding a better balance in variety quality. The
research shows clearly that in the context of bio-dynamic farming, OP varieties can have as
high yields as F1-hybrids. Variety choice can be made much more on the basis of taste and
quality, in addition to storability and yield.

1 Introduction
Currently, two trends in society are visible. One trend is that conventional breeding increas-
ingly focuses on F1 hybrid breeding and the use of patents. Another trend is that consumers,
in particular organic consumers, value product quality more and more. The need for an al-
ternative, more holistic approach in organic breeding becomes more urgent in order to
meet economic, societal and nutritional values (Lammerts van Bueren et al., 2016; 2018).
The breeding of open pollinated varieties has the potential to meet these values, important
for organic consumers. However, the choice of good open pollinated (OP) varieties in terms
of yield and some other traits is often limited as the focus in plant breeding has been on F1
hybrids for the past 40 years (Nuijten and Lammerts van Bueren, 2014). It is suggested that
the same yield is achievable with both F1 hybrids and OP varieties (Kutka 2011). However,
recent research findings show that OP varieties of several vegetable crops often have bet-
ter taste, but F1 hybrid varieties often have better yield (Nuijten and Groenen, 2014).
Nowadays, crop varieties have to meet many criteria. For farmers, next to yield, good field
traits, uniformity and storability are important traits. In organic agriculture, good taste and
good nutritional values are also considered important traits for crop varieties (Lammerts van
Bueren et al., 2011). Successful variety introduction in small markets like the organic sector is
complex but can be successful if it is adjusted to the needs of the market (Nuijten et al.,
2017). In the project ‘Divers and Dichtbij’ (Diverse and Closeby) the retailer Estafette Odin,
together with bio-dynamic farmers and the Louis Bolk Institute, evaluated open pollinated
varieties that combine good yield and storability with good taste and quality (Nuijten and
Lammerts van Bueren, 2016b). The reason to stimulate the use of open pollinated (OP) varie-
ties is to stimulate diversity not only at the plant level, but also at the socio-economic level:
with open pollinated varieties it is expected that more farmers can be involved in seed (pos-
sibility to multiply seeds on-farm in contrast to F1 hybrid varieties) and in selection towards
crop development (Nuijten and Lammerts van Bueren, 2015). Consumers not only value the
aspects of good taste and quality of such varieties, but also that they contribute to a broad
agrobiodiversity and maintaining open source in plant breeding.
Consumers expect organic products to have better quality and taste (Reinders et al., 2009).
Research on nutritional quality (based on mineral content) showed a drastic decrease in mi-
cro nutrient content (up to 60% for various minerals) of various foods such as vegetables, di-
ary and meat (Thomas, 2003; 2007). One explanation is the increased use of synthetic fertilis-
ers in conventional farming (Thomas, 2007). As in organic farming farmers use manure
(maintaining micro nutrients at sufficient levels in the field), one would expect clear differ-
ences between conventional and organic produce. However, there is not yet clear evi-
dence for this expectation (Nordholt et al., 2004). One reason why it is difficult to provide
8 A more holistic approach for breeding: including quality from a value chain perspective
such evidence is that it is based on a comparison of different farming systems with interac-
tions between many factors. Breeding can also be another factor that may contribute to
the decrease in minerals in crop varieties (Thomas, 2003; 2007)
In bio-dynamic farming research a concept has been developed that is called ‘growth and
differentiation’ referring to the balance and often trade-off in processes in plant growth and
hence also in crop production between creating quantity (kilo’s, vegetative process) and
quality (nutritional value, generative process). Generally plants show differentiation in the
leaf development from seedling to flowering plant. Plants that are more into the ripening
stage (closer to the flowering stage) have higher levels of dry matter content (Nordholt et
al., 2004), and are also expected to have higher levels of secondary metabolites (Bloksma
et al., 2002). The balance in growth and differentiation can be influenced through soil qual-
ity and plant breeding. A sandy soil is said to stimulate differentiation and the build-up of
dry matter and production of secondary metabolites , while a clayey soil is to stimulate
growth (Bloksma et al., 2002). Hence, one may expect that crop varieties with higher levels
of dry matter content are more nutritious. Project findings of the project Divers and Dichtbij
also show that there can be a positive relationship between dry matter content and taste
(Nuijten and Lammerts van Bueren, 2016). However, in some cases a negative correlation
between dry matter and taste seems to be related to the period of storage. It may also be
the case that this is variety specific. Such mechanisms are not yet well understood.
Project findings of the project Divers and Dichtbij also suggest that there can be a negative
relation between storability on the one hand and taste and quality on the other hand. Such
negative relationship has also been described by Watkins and Nock (2012). It means that
varieties with good taste are more difficult to store than the commonly used varieties by
farmers. However, storability has become a very important trait for farmers, as they need to
be able to sell their produce over a prolonged period of time.
An important question is what can be done to improve the storage period of vegetables
with high dry matter content (and hence good taste and quality). One option may be to
look for varieties that have a good balance in storability, taste and nutritional value. In oth-
ers words: to look for a balance in economic and quality aspects. Another option may be
to develop a specific marketing approach for such varieties.
In this research project the aim was to understand better several aspects important to the
underlying mechanisms of the growth and differentiation concept. One aspect is the com-
parison of the produce of two contrasting farms: one bio-dynamic farm with clay soil (the
farm GAOS in Swifterbant, the Netherlands) and the other with a sandy soil (the farm De
Beersche Hoeve, Oostelbeers, the Netherlands). Crops on the farm with sandy soil are ex-
pected to be more differentiated and therefore more advanced in ripening than the crops
Introduction 9
on the farm with the clay soil that tend to keep on growing. We expect to see clear differ-
ences in storability and taste. Comparing various OP and F1 varieties with different charac-
teristics will help understand whether a good balance in storability and taste is possible. An-
other aspect was to compare harvest dates: What is the effect of date of harvesting on stor-
ability and taste? The produce was tasted at several periods after harvesting to describe the
changes in taste during the storage period. Another aspect in relation to taste and storage
are plant related traits: do leaf, fruit and root crops have different optimal balances in taste
and storability? To understand this better, three crops will be compared: a cabbage crop
(red cabbage), a root vegetable (carrot) and a fruit vegetable (pumpkin).
The project findings may help understanding the possibilities of optimising cultivation, mar-
keting and storage of varieties with good dry matter content, taste and quality. Eventually,
this will need to be done together with partners in the value chain. In other words, with farm-
ers, traders and consumers.
The aim of this research
The focus of this research is to study various aspects important for successful cultivation of
OP varieties of different vegetable crops with good quality and taste, resulting in increase in
trade and higher consumption. In particular the effect of soil type and harvesting dates on
yield, storability, taste and quality were compared for a set of F1 hybrids and OP varieties.
Hypotheses
The hypotheses that were studied in this project are the following:
1. Storability is negatively related with taste and quality
2. Produce harvested on clayey and sandy soil behave very differently in storability and
taste
3. Cabbage crops and root crops grown on different soil quality behave differently in
storability and taste
4. There are crop varieties within a crop species that have a good balance in dry mat-
ter, taste and storability

2 Material and methods
Trial set up and methods
Based on discussions with the involved farmers (one biodynamic farm on clay soil in Swifter-
bant, one biodynamic farm on sandy soil in Oostelbeers), it was decided to work with the
following crops in this research project: carrot, pumpkin and red cabbage. Also, with the in-
volved farmers it was decided to look at date of harvesting (early harvest and conventional
harvest time) instead of two different storage regimes. The tested varieties are listed in Table
1. The choice of varieties was such to have sets of varieties that differ in taste, storability
and yield. For pumpkin, Bright Summer F1 has replaced Amoro F1 which was included in the
field trial in the first season. Bright Summer F1 is not as high in yield compared to Amoro F1,
and also has a higher dry matter content and mineral content. This replacement has the
benefit that as the extremes in the data set are not that large, the correlations may be more
informative to draw conclusions upon.

In both years the same trial set-up was used on both sites. On both farms a complete ran-
domised block design with three replications was used for each of the three crops. At both
farms, the trials for all three crops were sown and harvested as close together in time as pos-
sible. Due to dry and hot weather during sowing and planting in May 2017, the carrot trial at
the clay location had too low plant density, and with the red cabbage trial on sandy soil,
some plots had too low plant density. In 2018 all trials established well, but the red cab-
bage trial at the clay location suffered from high infestation with cabbage moth in June.
Generally, the summer of 2017 can be characterized as dry from May to August at both lo-
cations, with more significant amounts of rainfall from early September onwards that likely
has influenced the trial results. The summer of 2018 was even drier than the summer of 2017,
with almost no rainfall from May to August.
Material and methods 11
Field measurements
During the growing season, the trials in 2017 and 2018 were evaluated for criteria such as
plant habit, leaf development, plant health (presence of pests and diseases) and plant and
leaf development.
Evaluation of yield
For each of the crops, yield was measured twice, at an early harvest, and the normal har-
vesting time. Yield was measured at harvest and after storage in 2017 and 2018. At harvest
only gross yield was measured and recalculated in dry matter yield based on the dry matter
averages. After storage several additional parameters were measured such as amount of
rot and amount of produce that is unsuitable for sale, in this way being able to calculate a
marketable yield.
At both harvests of each crop representative samples were collected for laboratory anal-
yses. At the second harvest, samples were collected also for the three taste evaluations
over time.
The harvesting times were chosen as closely together in time as possible. In 2017, the har-
vesting time were as follows for respectively the sand and clay location:
Carrot: 1st harvest 5/7 September, 2nd harvest 4 October
Pumpkin: 1st harvest 5/7 September, 2nd harvest 21/22 September
Red cabbage: 1st harvest 21/22 September, 2nd harvest 12 October
In 2018, the harvesting time were as follows for respectively the sand and clay location::
Carrot: 1st harvest 19/20 September, 2nd harvest 4/5 October
Pumpkin: 1st harvest 23/24 August, 2nd harvest 11 September
Red cabbage: 1st harvest 19 September/5 October , 2nd harvest 4/18 October
In 2018, it was jointly decided with the farmers to harvest the pumpkins earlier because of
the warm weather and quicker growth than usual. The first harvest of the carrot in 2018 was
chosen later in time as early September (chosen in 2017) seemed to early. Due to the moth
infestation at the clay location in 2018, the harvesting of the red cabbage was delayed till
the cabbages were formed well.
Storability evaluation
The dates for storability evaluation were chosen such to ensure to see clear differences in
storability between treatments, in particular between varieties. Hence, the time of evalua-
tion was suboptimal for some of the varieties. With the evaluation for storability, also an eval-
uation for marketability was included: produce that was too small or had an irregular shape
(carrot and red cabbage) were not included in the marketable yield.
For carrot, storability evaluation was conducted on 1 March in 2017 and 28 February in
2018. For pumpkin, storability evaluation was conducted on respectively 22 January and 11
12 A more holistic approach for breeding: including quality from a value chain perspective
January in 2017 and 2018. Storability evaluation of red cabbage was conducted on respec-
tively 16 and 21 February in 2017 and 2018. The storability evaluations were chosen differ-
ently for each of the crops because of differences in storability potential. Of the three crops,
pumpkin has the shortest storage potential, and carrot the longest.
Taste evaluations
Taste evaluations were done with the involved farms at three moments in time for each of
the crops. Evaluations were conducted blind and the following traits were evaluated: gen-
eral taste appreciation, intensity of aroma, sweetness for carrot and pumpkin, length of af-
tertaste and structure/mouthfeel. Each trait was evaluated using a score of 1 (low) to 9
(high). For the taste tests, on average 9 people were involved, ranging from 6 to 12.
At the first two taste evaluations, all crops were evaluated on the same day. The third taste
evaluation was combined with the storability evaluation. For both years the first two evalua-
tions were chosen in time as closely as possible. In both years the first evaluation was con-
ducted on 18 October, and the second evaluation was on 8 and 6 December in respec-
tively 2017 and 2018. The third taste evaluations were combined with the storability evalua-
tion.
Laboratory analysis
In addition to analysis of dry matter content, Brix, EC and pH, also a so-called self-decompo-
sition test (SDT) was conducted as indicator for nutritional quality from a holistic perspective
(Bokhorst 1985). For this test the same plant material was used as for the measurements of
dry matter content, Brix EC and pH. For the SDT rasped material was kept in Petri dishes for 7
days at constant temperature and moisture conditions and then evaluated for appearance
and reduction in fresh and dry weight. For the analyses the following parameters were used:
decrease in fresh weight after SDT (in %), decrease in dry matter after SDT (in %) and the ra-
tio in decrease dry/wet weight after SDT. A low value for decrease in dry matter after SDT (in
%) and the ratio in decrease dry/wet weight after SDT are indicators for good nutritional
quality (Bokhorst 1985), and a high value for decrease in fresh weight after SDT (in %) is con-
sidered an indicator for good nutritional quality. Mineral analysis was outsourced, and for
some minerals no data were generated (Sodium and Manganese for pumpkin).
Statistical analysis
The software Genstat was used for statistical analysis, e.g. ANOVA and correlations, compar-
ing crops, varieties, locations, years and harvesting times.
Results 13
3 Results
First the results of the ANOVA will be presented, comparing crops and varieties per crop.
Then an overview on crop performance followed by correlations of storability (percentage
rot after harvest), taste, yield fresh (after harvest) and yield dry matter (after harvest) with
other traits will be presented per crop. Last, dynamics in development of taste are be de-
scribed per crop.
3.1 ANOVA
A comparison with all data of all three crops in one ANOVA shows many interactions for the
different types of traits: yield, storability, quality, taste and mineral content (Table 2). A com-
parison of all crops for only the season of 2017 shows no interaction terms for aroma, after-
taste, Brix and dry matter percentage. However, for 2018 also interaction terms (mostly crop
x location) were found for these traits. The results of the ANOVA per crop, combining both
seasons also show interactions for all traits that were measured both harvest dates. There
seem not be consistent differences or patterns between categories of traits and between
crops. The main effects (Variety, Location, Year, Harvest date) differ for these traits for each
of the crops.
Carrot
The ANOVA for 2017 and 2018 separately show no significant interactions for the traits de-
crease in fresh weight after SDT, aftertaste and pH (Tables 3a-1 and 3a-2). The F-values for
the main effects (Varity, Location and Harvest moment) differ for both years. For the other
traits, the results suggest that location and harvest date interacted in different ways in the
two seasons.
Pumpkin
The ANOVA for 2017 and 2018 separately show no significant interactions for the traits de-
crease in fresh weight after SDT and pH (Tables 3b-1 and 3b-2). For all other traits interactions
were observed in both years or in one of the two years. In 2017, fewer interaction were ob-
served than in 2018.
Red cabbage
The ANOVA for 2017 and 2018 separately show no significant interactions for the traits after-
taste, pH and EC (Tables 3c-1 and 3c-2). In 2018, fewer interaction were observed than in
2017. In 2018, no significant interactions were observed for the term Variety x Harvest date.
Crop performance
Some general trends are that whereas total yields (fresh matter) can differ widely among
varieties of the same crop, the differences in dry matter yields are smaller (Tables 4a, b, c;
for all averages: Annex 1). Another trend was that storability on clay soil tends to be better
14 A more holistic approach for breeding: including quality from a value chain perspective
for all crops. For pumpkin and red cabbage taste tended to be better on sandy soil com-
pared to clay soil. For carrot taste on clay soil tended to be better in 2018, but in 2017 taste
for carrot was similar on both locations.
Carrot
Some general trends that were observed are that storability, quality and taste were better
on the clay soil location than on the sandy soil location (Table 4a). However, taking into ac-
count year-effects, a complex picture emerges. Marketable yield after storage was the
same for both years at the clay location, but differed a lot on the sandy location. Taste was
similar for both years at the sand location, but differed for the clay location.
Results suggest that harvest moment 1 resulted in better quality and mineral content, but
that harvest moment 2 results in better taste, yield, storability and marketable yield. Particu-
larly on clay soil, in both years, the crop may have accelerated growth between the two
harvest dates because of increase in rainfall.
Pumpkin
For pumpkin, fresh yields varied for clay between 2017 and 2018, whereas the dry matter
yields were similar (Table 4b). On sand the fresh yields were very similar between the two
years, but the dry matter yields differed much. In both years storability on clay was better,
whereas taste was much better on sandy soil.
Despite lower yields of harvest moment 1 compared to harvest moment 2, marketable yield
of harvest moment 1 was better. Also storability and taste were better for harvest moment 1
compared to harvest moment 2.
The results of the SDT suggest that the quality of the second harvest in 2018 was better than
the first harvest, but dry matter content, Brix and EC were better for the first harvest. Results
of the SDT test for 2017 suggest similar quality for both harvesting moments. Dry matter con-
tent in 2017 was higher with the first harvest, but EC was higher with the second harvest. In
2018 the development stage of the plants was larger compared to 2017.
Red Cabbage
For red cabbage the general trends are that storability was clearly better on clay than on
sand, but that taste was better on sandy soil (Table 4c. Yield data were limited because part
of the trial on the sand locat
ion could not be used for yield measurement in 2017 due to heat stress after planting, and
the trial on clay was considered not representative for yield in 2018 due to a severe moth in-
festation in June.
Harvest moments 1 and 2 seem not to differ clearly for storability, quality and taste. In re-
spect to yield, it seems harvest moment 2 is better in general.
The biggest differences in storability, quality and taste can be observed between varieties.
An observation in the field was that the varieties that were slow in head formation, Roxy F1
and Travero F1, (and to a lesser extent Marner Lagerrot) had better storability and higher dry
Results 15
matter content. The SDT data suggests that with the first harvest the variety Rodynda had
best quality, and with the second harvest the variety Marner Lagerrot.
3.2 Correlations
Correlations for the traits storability, taste, yield fresh and yield dry matter differed for each of
the crops in different ways (Tables 5a-1 to table 5c-4). The strength of the correlation varied
much based on the data set used per crop: all data, Location (clay / sand), Year
(2017/2018), Harvest moment (1 / 2) and variety (five per crop). Also the direction of the
correlation (positive / negative) varied for most traits between the crops.
Correlations on storability
In regards to storability, fewest correlations higher than 0.6 or lower than -0.6 were observed
for carrot, and more for pumpkin and red cabbage (Tables 5a1, 5b1, 5c1). In general corre-
lation values were mostly low. Brix showed the most consistent pattern (mostly positive) for all
three crops. Of the other traits decrease in fresh weight after SDT showed the clearest pat-
tern, with mostly positive correlations for pumpkin and red cabbage but negative correla-
tions for carrot.
For pumpkin, storability (percentage rot) showed a consistent pattern in negative correla-
tions with EC ,a positive pattern with dry matter yield and a large number of high positive
correlations with taste. For red cabbage, about 50% of the higher correlations were ob-
served with the varieties Granat and Rodynda, suggesting a strong variety component.
These two varieties also grow faster than the other three red cabbage varieties.
Correlations on taste
For taste, more correlations higher than 0.6 or lower than 0.6 were found with pumpkin than
with carrot and red cabbage (Tables 5a2, 5b2, 5c2). Particularly for taste the correlations
could differ much between the two locations, the two seasons and also the two harvest mo-
ment.
For pumpkin, next to the correlations with storability and dry matter yield, many high correla-
tions were observed for Brix/EC and many negative correlations with EC. For 2017 and har-
vest moment one stronger correlations were found than for 2018 and harvest moment two
respectively. For carrot and red cabbage, strongest correlations were found for the taste
related traits aroma and aftertaste. For carrot, also harvest moment 1 had stronger correla-
tions than harvest moment 2. For red cabbage, most correlations were related to the varie-
ties Marner Laggerrot and Roxy F1.
Correlations on fresh yield
No strong correlations were observed between yield and taste and storability for all three
crops (Tables 5a3, 5b3, 5c3). Most correlations were found with carrot. Average dry matter
and Brix content predominantly showed negative correlations with yield, with the strongest
16 A more holistic approach for breeding: including quality from a value chain perspective
correlations for pumpkin. Carrot also showed strong negative correlations between dry mat-
ter content and yield. In addition carrot also showed negative correlations between yield
and EC and decrease in fresh weight after the SDT, and showed positive correlations be-
tween yield and the ratio of decrease in dry and wet weight after the SDT.
For pumpkin and red cabbage these traits showed much lower correlations. It is noteworthy
that for all three crops yield and EC showed strong negative correlations for 2017, but not for
2018.
For red cabbage, yield showed many strong correlations for harvest moment two.
Correlations on dry matter yield
Like for fresh yield, no strong correlations were found between dry matter yield and taste
and storability (Tables 5a4, 5b4, 5c4). Most correlations were found with pumpkin and carrot.
None of the traits showed a similar pattern of correlations for all three crops. For carrot and
pumpkin, the year 2017 showed stronger correlations than the year 2018.
The high number of strong correlations with pumpkin seems related to EC which was nega-
tively related to dry matter yield. Also ECxBrix was strongly negatively related with dry matter
yield. The ratio Brix/EC was positively related to dry matter yield. For carrot, next to EC and
pH, the SDT related traits showed strongest correlations with dry matter yield, but not as
strong as EC in the case of pumpkin. In the case of red cabbage, most correlations with dry
matter yield were found for harvest moment 2.
3.3 Taste evaluations over time
For each of the crops different patterns in taste were observed. These patterns were differ-
ent between varieties of the same crop, but also different for the same variety between the
two locations and the two seasons. Both location and season can influence the develop-
ment of taste of a single variety. This also means that taste depends much on time of evalu-
ation. This was particularly the case for pumpkin, and perhaps less so for red cabbage (Ta-
bles 6 and 7).
For carrot, three varieties (Crofton F1, Nerac F1 and Robila) showed a similar pattern in 2017:
decrease in taste on clay soil and improvement in taste on sandy soil. Solvita from clay soil
had better taste than from sandy soil on all three taste evaluations. The variety Rodelika de-
scribed a somewhat irregular pattern in taste, with the best taste evaluation in December.
However, in 2018 each carrot variety showed a different pattern in taste development com-
pared to 2017.
For pumpkin, patterns in taste development were even more complex in 2018 compared to
the already different taste developments of the various varieties in 2017 with often decreas-
ing taste on clay soil and improving taste on sandy soil. This was particularly the case for the
varieties Red Kuri and Uchiki Kuri. The only variety for which the taste patterns in 2017 and
2018 were similar was the variety Fictor. The variety Fictor also showed consistent patterns in
taste for clay and sandy soil, e.g. large differences, at all three evaluations in both years.
Results 17
The most constant variety seemed to be Orange Summer F1, although it also had some
changes in taste in the season of 2018.
For red cabbage, also differences in patterns of taste development were observed. Loca-
tion and season effects seem to be different for each of the varieties. Perhaps the only vari-
ety that seems to have a stable pattern in taste development in both seasons for both loca-
tions is the variety Travero F1. Also the variety Marner Lagerrot seems quite stable over time
on the sandy location, but less so for the clay location. In particular the taste developments
of the varieties Granat and Roxy F1 seem different for the two locations in the two years.
18 A more holistic approach for breeding: including quality from a value chain perspective
4 Discussion
The focus of this research was to study the relationships of various aspects (soil type, season
and harvest moment) important for successful cultivation of OP varieties of different vegeta-
ble crops with good quality and taste, resulting in increased cultivation trade and higher
consumption. An important question was whether a balance in yield, storability, taste and
quality is possible. Three different crop types (cabbage, root vegetable and fruit vegetable)
were used in order to understand which general conclusions can be drawn. The analyses
show that there are many interactions between varieties, soil type, season and harvest mo-
ment. And that these interactions can be different for the three crops. One general conclu-
sion is that whereas yields can differ a lot between varieties when calculated in fresh matter,
yields are much more similar when calculated in dry matter. Correlations also suggest nega-
tive relationships between yield fresh matter) and quality (in particular dry matter content).
These relationships seem clearest for carrot. It suggests that breeding for higher (fresh mat-
ter) yields results in lower quality. In other words, the nutritional quality becomes diluted. This
information may not only change the perspective on variety choice, but even on breeding.
Whether this insight can be integrated into daily practice depends on the choices made in
the value chain.
Another general conclusion is that soil quality has a big effect on storability and taste (hy-
pothesis 2). This is in agreement with the growth and differentiation concept (Bloksma et al.
2002). In this research the storability on clay soil tended to better than on sandy soil. For
pumpkin and red cabbage taste was also better on sandy soil than on clay soil, which is also
in agreement with the growth and differentiation concept. However, carrot from clay soil
tended to taste better than from the sandy soil in this research. This is not in line with earlier
ideas on taste and soil type (Bokhorst, 1985). However, the weather of 2017 and 2018 was
quite a-typical for Dutch standards. Hence, in another year with more ‘normal’ weather
findings may be more in line with earlier ideas. The data on dry matter content for carrot
were quite different from those measured in 2014 on the same farm on the clay location
(Nuijten and Lammerts van Bueren, 2016).
From the growth and differentiation perspective improved storability can be achieved by
harvesting the crop when the plants are more in the growth stage than in the differentiation
stage (Bloksma et al. 2007). However, the differentiation stage is important for quality and
taste. From this logically follows that improved storability is negatively related with taste and
quality (hypothesis one). The results on pumpkin are well in line with this hypothesis. How-
ever, the results on carrot and red cabbage cannot confirm this hypothesis. The results on
carrot suggest a negative relation between improved storability and quality but none with
taste. Data on red cabbage seem not to suggest clear relationships between storability
and taste and quality. A complicating factor here is that there are several parameters used
Discussion 19
as an indicator for quality: dry matter content, Brix, EC, and the SDT parameters. How ex-
actly these parameters can be used as indicator for what sort of nutritional quality needs to
be better studied. The ANOVA’s suggest that SDT parameter ‘decrease in wet weight after
the SDT’ seems to be the more stable parameter of the SDT parameters and hence may be
more suitable as indicator for quality. Of the other quality related parameters EC seemed
most stable for red cabbage. Another parameter that did not show any interactions in the
ANOVA of each of the three crops was pH. Whether this is because pH needs to be rela-
tively stable anyhow, or that it can be used as indicator for quality in combination with other
quality parameters needs to be further studied.
Time of harvesting seems to have a large effect on the outcomes of the correlations of taste
with many other parameters, for all three crops. When starting up the research, the effect of
harvest moment was an important element of discussion. The results suggests different pat-
terns in the effect on storability, taste quality for each of the crops (hypothesis 3). In general
an earlier harvest moment can have positive effects on storability, taste and dry matter con-
tent in the case of pumpkin. However, correlations with taste and storability are very differ-
ent for the first and second harvest moments, suggesting that a later harvest moment has
better nutritional quality (based on the SDT parameters), although lower dry matter and min-
eral content. For carrot, an earlier moment may have positive effects on mineral content
and perhaps even nutritional quality (contrary to the growth and differentiation theory), but
negative effects on taste, yield and storability. For red cabbage, the moment of harvesting
seems to have little effect on storability and taste. A complicating factor in both seasons
was that shortly before or in between the harvest moments rainfall started again, causing
the crops to start, or accelerate, growth again. This was particularly the case for carrot in
both years and also for pumpkin in the second year. Hence, at the second harvest moment
some varieties may have been still in a growth phase.
The assumption was that a good comparison of three crops is improved by using several va-
rieties in the comparisons. One the hand using several varieties per crop is important to un-
derstand which general lessons can be drawn. On the other hand, the set of varieties has
different qualities for each of the crops. Hence, it is difficult to draw more solid conclusions.
This seems particularly the case for red cabbage of which each variety seems to have very
different qualities, such as taste, storability and nutritional quality. For example, the SDT pa-
rameters suggest that the variety Marner Lagerrot has good nutritional quality but it scored
relatively low in taste because of its typical cabbage taste which nowadays is being less ap-
preciated. Also, the correlations with taste were positive in the case of some red cabbage
varieties but negative for other varieties for the same traits.
As a general conclusion it may be argued that it should be possible to breed for crop varie-
ties with a good balance in yield (fresh), dry matter yield, taste and storability (hypothesis 4).
20 A more holistic approach for breeding: including quality from a value chain perspective
How this balance should look like exactly for each of the crops is a point of discussion with
farmers, traders and consumers. Presentations of the first results to farmers and consumers at
several occasions in 2018 underline the importance of finding a better balance in variety
qualities. The research shows clearly that in the context of bio-dynamic farming, OP varieties
can have as high yields as F1-hybrids. Looking at yield from the perspective of dry matter,
differences between varieties become very small. Choice of varieties can then be made
much more on the basis of taste and quality, in addition to storability. The research also
shows that many factors (soil, season, harvest moment) interact and influence variety per-
formance. Which varieties are best to be used is not only depending on preferences in the
value chain, but also depends on the local agro-ecological context.
