Soil-climatic conditions of the majority of oases of Republic Uzbekistan allow using intensively the irrigated grounds after cleaning wheat on a grain for cultivation of high crops early grain and forage crops for reception of a fodder grain, a silo and green forages prior to the beginning of autumn frosts. One of the major factors of an intensification of irrigated agriculture is deducing and introduction in manufacture of high-yielding hybrids of corn. The corn-valuable grain both fodder culture and attaches great importance to its selection (Tillaev, 2000). On the State sites on test of grades of agricultural crops have been tested the big set of early hybrids (FAO 180-400) selections the USA, Germany, France, Hungary, Slovakia and Moldova. Best of them ripened for 83-97 days at crop after cleaning grain - grains and of a grain 5.0-5.7 t/hа yielded a harvest. However now in industrial crops only are in part used Hungarian and Moldavian hybrids, and crop is carried out by extremely brought in seeds. Seed-growing of these hybrids directly in Republic restrains by virtue of low adaptable parameters of initial parental forms (Massino, 2005).
