Abstract: Wheat is on* of tao most laportaat e*reals and staple food crop of the world, occupying the fourth plaoa in cultivation of the toed crops. DeCaadolle (1883) la his classical monograph en the origin of cultivated crops, suggested Mesopoteala as the possible centre of origin of the cultivated wheats and thought its cultivation spread oil over the world through the invasion of shepherds and through too nediom of Hebrew Scriptures. Vavilov(19a6, 1930, 1049) determined the existence of priaary and secondary centres of origin of wheats in Asia-Minor, Mediterranean basin, Abysinia and Afghanistan. It It sow widely cultivated throughout the world* According to Pal (i960) the total acreage under wheat la the world is about 428,000,toot^aores with aa aanual production 1T4,900,000 tonnes. As a producer of wheat, India occupies the fifth position la the world aa regards acreage and seventh la respect of yield. Wheat cultivation la India dates back to the unrecorded ancient periods,prior to, 3,000 B.C. At present, the area under this crop la India, has been estiaated to be S3 allllon acrea aad production of grain at about 16 willion toaaoa (Sangave, 1965). fritlea* aeativna. too bread wheat and T. durujs. hard wboat are the two speoies wost cooaonly cultivated la the major wheat growing areas of Xadia like Punjab, Cttar Pradesh, Northern Hejasthan, Bihar, Maharashtra, Madhya Iradash and - a * Peninsular India, fas two species are grown Is soae parte of Mysore (Nllgirls ) and Andhra Pradesh, Wheat oeouples IS# of the total acreage of all food grain* grown in India (Murthy, 1»E8). II is MI iajportant eoroal orop of Maharashtra and according to Sangave (19«8) it occupies an araa of about 8,4 Billion acraa i,a. S$ #f the total araa under variola crop*. the average yield of wheat par acre is Maharashtra is very low, i,e, ISO kf/acra as oeapared to 499 kg/aero la Punjab* It la cultivated la all districts of Maharashtra except Koakan aoatly as a dry orop^ T» 4araa Doing coaaea* wheat grata is very nutritious being rloher la proteins than siost other o a real grains; it la used la preparing a variety of foods, especially, Chapatlca.
