Sorghum foods

Sorghum grain is nutritionally superior to fine cereals like rice

because of its high mineral and fibre content. Because of its

slower digestibility, sorghum is also being recommended for

diabetic and jaundice affected, and obese people. Sorghum

does not have gluten and therefore becomes a very good

gluten-free energy source as many are allergic to gluten.

However, due to the difficulties in processing for different

foods, its usage is limited in urban areas. The feasibility of

using sorghum for the preparation of different traditional and

non-traditional foods replacing rice and wheat is given here

with the prime objective to spread awareness about the

nutritional qualities of sorghum and to popularize the recipes

for sorghum foods that can be easily made among rural and

urban population

Sorghum grains were made in to flour as well as rawa (suji)

of different particle size (coarse rawa, medium rawa and fine

rawa). Sorghum is made in to a fine flour by using a grinding

mill (Nima flour mill, India) with sieves of semi-fine and fine

grades. Sorghum rawas of different particle size were

prepared using coarse and medium sieves. Rawa and flour

are manually separated with fine hand sieves. Different food

products like roti, cake, pakoda, chakkalu and muruku are

prepared from sorghum flour using the other ingredients

required. Sorghum rawa (coarse) was used for the preparation

of upma and halwa (kesari) sweet item. Fine rawa from

sorghum was used in making upma, halwa (kesari) and laddu.

Sankati is prepared using both flour and rawa. The taste and

texture of the products were evaluated through distribution

during official meetings, and gatherings of staff of ICAR at

Hyderabad and elsewhere to spread awareness of various

possibilities with sorghum.

Sorghum can be replaced in many of the breakfast and snack

foods that are prepared from fine cereals such as rice and

wheat. Though preparation of roti from sorghum flour is difficult

due to the lack of gluten, the other foods can be prepared

with ease.

Sorghum for breakfast foods : Sankati, dosa, idly and upma

can be prepared from sorghum rawa and flour. Among them

sankati is traditional and upma, idly and dosa are urban foods.

Sankati Dosa

Upma Idli

Sorghum for lunch: Sorghum annam (“rice”) and roti can

replace rice and wheat dishes for lunch. Annam is made from

Annam Roti

boiling pearled sorghum and rotis made from sorghum atta.

However, making rotis from sorghum atta is a skilled job. Roti

making machine is also available (see below) to make them

on a commercial scale. The composite flour made from

sorghum in combination with pearl millet, wheat, and

soyabean is more ideal with its improved nutritional quality.

Sorghum for snacks food: Sorghum can be used for making

three different snack foods such as pakoda, muruku and

Roti making machine Roti baking

Chakkalu Murukulu Vegetable Noodles

Jowar Samachar, Volume 3, No.1 Page 3 of 8

chakkalu easily replacing the cereal component, which is mostly

rice. Sorghum tends to absorb less oil during these

preparations.

Sweet dishes with sorghum: Sweet dishes that can be

prepared from wheat rawa can be prepared from sorghum

rawa also. The only difficulty is

the availability of sorghum

rawa. NRCS is making efforts

to popularize the sorghum

rawa of different particle size.

The fine rawa is being used for

making rawa Kesari and Laddu.

Kesari Laddu

Kheer

Fine rawa can find a good market as this can be used for

many preparations. The noodles made from sorghum can be

used for the preparation of Kheer.

Sorghum for baked foods: All the popular bakery foods

such as bread, cake, bun and biscuits can be easily prepared

Bread Biscuits

Cake

with fine flour of sorghum

(flour specially made for

bakery foods). Sorghum is

pearled before it is made in

to a fine flour. Cake is made

with 100% sorghum flour

where as bread, buns and

biscuits are prepared adding with maida up to 40%. Shelf life

and cost of production of these items is same as that of baked

items made from wheat flour/maida.

Training and Entrepreneurship Development : NRCS is

deeply involved in training individual and volunteer business

groups to make above products and market. Please contact

Pant Chari 6- New Multicut Forage Sorghum

Variety for Uttarakhand

For the benefit of Farmers and Dairymen of the Uttarakhand,

a high yielding and highly nutritious multicut forage sorghum

variety Pant Chari 6 has been released for commercial

cultivation by the Uttarakhand State Variety Release Committee

in November, 2004. The variety has been notified by the

Central Sub-Committee for Notification in its 43rd meeting

held on May 31, 2006.

Pant Chari 6 showed 5-12 % yield superiority over checks in

the All India Coordinated trials and in State trials conducted at

Pantnagar, Khatima and Chinyalisaurh in Uttarakhand. It has

also shown 40-50% superiority over Local varieties in Front-

Line Demonstrations conducted at farmer’s fields in the districts

of Haridwar, Udham Singh Nagar, Dehradun, Nainital and

Champawat.

With average yield of 700-800 q/ha green fodder in 3-4

cuttings, Pant Chari 6 has highly nutritious fodder. It has

7-8% crude protein, 55-58% digestibility, 7-8% TSS

(sweetness) and very low HCN content (less than 100 ppm). It

has high tillering capacity with fast re-growth after cuttings. It

is resistant to foliar diseases like anthracnose and zonate leaf

spot. Pant Chari 6 has semi-compact large panicles which

produce medium bold, easily threshable, light brown color

seeds. The better seed yield potential (18-20 q/ha) is an added

advantage of Pant Chari 6 for the fast dissemination of this

variety. Large scale breeder seed production of Pant Chari 6

is being taken up at the Seed Production Centre of Pantnagar

University. For popularization of variety the seed of Pant Chari

6 is being given in the form of Minikit to the farmers during

Farmer Fair at Pantnagar besides including it in the Front Line

Sorghum Germplasm Collection from Melghat

region of Maharashtra

Two-day sorghum germplasm collection mission was

undertaken from tribal areas of Melghat region in Maharashtra

during kharif 2006 and 25 accessions were collected. One

Sorghum halepense germplasm was also collected from the

khoga river belt of Satpura hill range in Melghat Tiger Project

region.

The landraces viz., detha, bhad (add type in Marathi), lahya

phodi, ramgi, somgi, and nariyal jola (shape like coconut) are

collected during the mission. In these regions, Korukoo’s (tribe)

grow somgi and desi jonna landraces. They cultivate sorghum

with lablab, chillies, cotton, redgram, and tomato. The shape

of bhad jonna earhead is like mango and the landrace grow

very tall and the stalk sweetness also very good and it may be

utilized in the sweet sorghum programme. The ramgi jonna is

having very big earhead, very bold and flat seed may be

utilized in the dual-purpose sorghum programme.

Café Ethnic -An Exclusive Millet Restaurant

Deccan Development Society situated in the semi-arid

Telengana region of Andhra Pradesh has a millet-based

restaurant “Café Ethnic” operational in Zaheerabad, 100 km

from Hyderabad, since 2004. In this part of the region, jowar

and millets were the mainstay a till a couple of decades ago.

However with the PDS programme of the AP government,

rice took precedence over the traditional crops of the region,

and as a result people in a way developed amnesia over their

food habits and culture. With this backdrop, Café Ethnic initiated

a path-breaking task of reviving the food culture of this region

and is making an unflagging effort to give millets its rightful

place in the food map of the region.

Refreshing and nutritious snacks made of Jonna (Jowar or

Sorghum) Korra, (fox tail millet) Saama (little millet) Taida

(finger millet) Sajja (pearl millet) are the delight of the café.

Being made from millets, these foods are more nutritious.

The society considers it an important step we are taking in

furthering the cause of dryland crops and bringing back

forgotten foods for urban consumers.

Sorghum in Indian Postal Stamps

A special cover depicting the sorghum panicle in the

cancellation stamp was released by Sri. HB Hirevenkangoudar,

Chief Superintendent of Posts, Bijapur, Karnakata, on 13th

November, 2006 during the three-day philately exhibition

“BIJAPURPEX-2006”. Dr. BD Biradar, AICSIP - Bijapur spoke

on the importance of sorghum and appreciated the use of

sorghum in Indian postal stamps in his presidential remarks

BD Biradar, AICSIP, UAS Dharwad, Bijapur, Karnataka

Genetics of brown-midrib trait in sorghum

Sorghum forage quality is influenced by many factors,

including harvest stage, juiciness and sweetness. However,

the development of the brown-midrib (bmr) trait in sorghum

has overshadowed these traits and provided great results for

reduced lignifications, reduced cell-wall concentration,

increased digestibility, and increased voluntary intake of feed

by ruminants. This mutation signifies the single most rapid

and valuable mechanism of genetically modifying nutritional

value of forage sorghum. However, recent experience in the

USA has shown that all brown midrib types don't yield highly

digestible forage.

The brown midrib mutant (bmr) was first isolated in sorghum

by Porter et al., 1978. This mutant was phenotypically identified

by the brown pigmentation of the leaf midrib which is more

pronounced on the abaxial surface, and the brown pigmented

stem pith. A series of the sorghum bmr mutants (bmr6, bmr12,

bmr18, bmr19, bmr26 etc.,) have been identified which are

linked with reduced lignin production and increased forage

digestibility. Studies have indicated that the mutation bmr6 is

associated with reduced cinnamyl alcohol dehydrogenase

(CAD) enzyme activity, the other mutant alleles (bmr12,

bmr18, bmr26) decreases the activity of the enzyme caffeic

acid O-methyltransferase, both of which are involved in the

lignin biosynthetic pathway.

Looking into the importance of brown midrib trait in improving

the stover quality of sorghum, at NRCS a study was conducted

to know the inheritance of brown-midrib trait in sorghum. A

F1 hybrid between E36-1 (white-midrib) x IS21887 (brown-

midrib) genotypes was made during the rabi season of 2005-

06, and the F1 was planted during kharif season of 2006 to

advance to F2:0 seed. F2 progeny was raised during rabi

season of 2006-07 at NRCS. Phenotypic observations on

brown-midrib and white-midrib were recorded at pre-bloom

stage from each of the F2 progeny. The goodness of fit

between the observed and expected segregation pattern for

white-midrib and brown-midrib phenotypes in F2 was tested

using chi-square test.

Brown-midrib (IS21887) White-midrib (E36-1)

The F1 hybrid had white-midrib indicating dominance of white-

midrib over brown-midrib phenotype. The F2 segregation

for this trait revealed the operation of a single gene as

indicated by the good fit of 3:1 ratio. Out of the185 F2 plants

scored, 150 had white-midrib while 35 showed brown-midrib,

thus fitting the overall segregation into a good fit of 3:1 ratio.

Therefore, it is evident that the midrib trait in the parents

studied is under monogenic control, and the brown-midrib is

inherited as a recessive mutant. As a recessive mutation,

brown-midrib trait can be backcrossed readily into elite

sorghum lines to add value to crop and animal systems by

enhancing the digestibility of the sorghum stover.
