aref2 The research objective was to define the efficacy of use of a local adaptive gene pool of winter wheat with high potential of productivity and with a complex of economic valuable signs to obtain breeding material, which is more resistance to lodging. In spent top-crossings the maternal form was the semidwarf line L-982/08 (AgapikPamyati Fedina), and paternal ones were 10 varieties of winter wheat of breeding of Moscow Research and Development Institute of Agriculture Nemchinovka (Zarya, Inna, Pamyati Fedina, Moskovskaya 39, Galina, Nemchinovskaya 24, Moskovskaya 56, Nemchinovskaya 57, Moskovskaya 40, Nemchinovskaya 17). The line 982/08 is notable for high productive density (561 stalk/square m), short height of plants (0.68 m), low weight of grain from an ear and thousand-kernel weight. The height of plants in combinations in F1 varied from 0.78 m to 0.92 m. It was showed the domination in height of father's higher form, incomplete one C in 7 combinations, intermediate one C in two combinations, and overdominance in one combination. In F2 height of plants in all combinations was intermediate between parents. The heritability factor (I2) in 9 combinations varied from 0.16 to 0.62, that testified the strong influence of external factors, and only in hybrid L-982 Zarya with factor 0.78 there was visible effect of the genetic factor. In the majority of hybrids F1 the weight of grain from an ear with overdominance was higher, than in the paternal form. On thousand-kernel weight the influence of large grain fathers had an affect with incomplete dominance (0 hp 1) and overdominance (hp 1). Heritability of grain quantity in an ear and its weight in F2 had low values at I20.7. Hybrids possessed the lowered height and raised number of grains and their weight in an ear compared to parental form. In generation F3 the best lines in combinations with Nemchinovskaya 17, Pamyati Fedina, Nemchinovskaya 57, Moskovskaya 40 and Galina reliably exceeded parental forms with the maximum value of productivity in the range from 0.630 to 0.475 kg/mE2. As a result semidwarf line L-982/08 (Agapik Pamyati Fedina) was recognized as the donor of short-stalkedness. The character of inheritance of plant height and elements of ear productivity, number of grains, weight of grain and thousand-kernel weight, is established in F1 and F2. Highly productive lines in combinations with variety Nemchinovskaya 17, Pamyati Fedina, Nemchinovskaya 57, Moskovskaya 40 were selected with height of plants 0.6-0.68 m. The valuable breeding material is created.
