(a) Cereals: They belong to family Gramineae. There yield grain or single seeded fruit called caryopsis.
(i) Rice (Oryza sativa):
It is a Tropical crop now grown in almost all parts of India. In North India it is grown as Kharif crop but in other parts 2-3 crops are raised. It is a staple food of 60% of world population and more than 50% Indians. 90% production in Asia. Grain husk is called paddy. Rice is deficient in protein. Rice bran yields oil. Basmati is flavoured rice cultivated in parts of D.P. and Haryana. It contains 90% starch & 8-10% protein.
(ii) Wheat (Triticum aestivum):
Temperate crop grown in North India. Staple food in majority of the
countries. Its Tonnage output is more than Rice and Maize. Two types of it include:
(1) Durum Wheat (Triticum durum) which is ‘tetraploid and grows in drier parts, used in macroni and noodles.
(2) Bread Wheat (Triticum aestivum = T. vulllgare) is hexaploid and employed in making bread, cakes, chapaties etc.
Wheat contain 60-70% starch’and 10-17% protein.
(iii) Maize (corn = Zea mays):
It is the tallest cereal from New World. It cannot tolerate ground frost. Maize grains yield popcorn (Zea mays var, everta), flour corn oil, corn starch and protein Zein (for artificial fibre and foamming agent in fire extinguisher).
(2) Minor Cereals and Millets:
Rye (Secale cereale), Oat (Avena sativa), Barley (Hordeurn vulgare) and millet are called minor cereals. Millets
(i) Jowar, Great Millet (Sorghum vulgare or S. bicolor). It is raw material for malting industry. It is food for poor and also cattle i.e., it is also fodder.
(ii) Bajra (Pearl/Bulrush Millet or Pennisetum typhoides – P. americanurn): It is food for poor and is small sized grain.

(Family Leguminosae, Sub-family Papilionodeae). These are legume seeds. Green pods are also used as vegetables. Pulses are rich in proteins. However, some of them lack amino-acids lysine, tryptophan and methionine. Soyabean is the richest plant food (36.5% protein) which is given to diabetic patients. Higher protein content is due to symbiotic root nodule bacterium of genus Rhizobium.

(iv) Green Gram (Mung) Vigna radiatus = Phaseolus aureus.
(v) Pea (Mattar) Pisum sativum. It contains 7.2% protein, 15.8% carbohydrate and also some vitamins. It is eaten green or canned or as vegetable.
(vi) Soyabean (Bhat) Glycine max. It is is eaten roasted or as milk which is a refreshing drink. It also yields oil.
(vii) Mat Bean (Moth) Vigna aconitifolia = Phaseolus aconitifolius.
(viii) Lentil (Masur) Lens esculentua = L culinaris.
(ix) Red kidney bean (Rajmah) Phaseolus vulgaris.
(x) Lablab Lablab purpureas = Dolichos lablab.
(xi) Guar/Claster Bean. Cyamopsis tetragonolobas.
(xii) Moongphali (groundnut) Archis hypogea. It is rich in protein. Eaten roasted or as vegetable ghee.
(xiii) Cow Pea Lohia Vigna unguiculata (V. sinensis) – Phaseolus lunetus: Lathyrism, a crippling dissability marked by muscular weakness, tremors and paraplegia is caused by eating seeds of Lathyrus sativus (Grass Pea, Chickling vetch, vern, Khesari Dal). The seeds contain osteotoxin B-amino Propionitrile (BAPN) and water soluble neurotoxin B-N-oxalyl amino alanine (BOAA). Red Kidney Bean and French bean possess lectins which are destroyed only on boiling for some time. Low temperature cooking or eating raw soaked beans can be dangerous.
