USE
Germplasm conservation Medium term orthodox seed storage at 8°C in Addis Ababa
Most original collection and long term orrthodoxseed storage at -20 °C in Addis Ababa
Field genebank for grasses with short-lived seeds or low seed production in Zwai and Debre Zeit
Safety backup of original collections in Centro Internacional de Agricultura
Tropical in Colombia and Svalbard Global Seed Vault in Norway
Information Global catalogue of forage germplasm available to improve access to and support improved
use and adoption of forages
Fact sheets on key species
Databases, decision support tools and web sites developed for improving conservation,
management and use of forage diversity

Phenotypic characterization Morphological characterization using standard descriptors
Diversity assessment Approaches and molecular methodologies for quantifying variation, developing
core collections, identifying duplicates and confirming taxonomic identity
Agronomic evaluation Diversity in yield, plant components and adaptation
Disease tolerance and drought traits in Napier
SAVE STUDY
Nutritional evaluation Studies in variation in nutritional parameters
Seed production Seeds of 60 best bet forages produced to support technology transfer in sub-Saharan Africa
Selection of forages and action research with farmers
NARS partners trained in forage management and forage seed production
Challenge: How can the forage collection best serve poor smallholder livestock keepers?
Model or representative forage species
selected for research based on:
Importance as forage or food-feed crop
Link to other work in ILRI
Work in partnership and complementary
Large amount of variation
Knowledge gaps
Representation in ILRI collection

Genetic relationship and disease susceptibility between accessions of Napier grass
susceptible
Forage germplasm Forage accessions conserved, documented and
disseminated according to international standards
under the International Treaty on Plant Genetic
Resources for Food and Agriculture
3000 samples per year distributed free of charge
for forage research and development worldwide
Regeneration Seeds regenerated for storage when viability or stocks are low
Disease free seeds of 800 accessions regenerated per year
Monitoring viability during storage Legume seeds monitored at 10 year intervals
Grass seeds monitored at 5 year intervals
Accessions with low viability scheduled for regeneration
Germination regimes identified for breaking dormancy
Monitoring health Legume seedlings tested for virus before planting or during growing season
Napier grass tested for Napier stunt disease after each cut
Infected plants removed from field
Virus elimination using thermotherapy and meristem culture
Disease screening for anthracnose for accessions of Stylosanthes once
during storage
Infected seeds discarded
Capacity NARS capacity in forage conservation, characterization, research and
development strengthened
Training manuals on genebank management
