Purpose of work: assessment of breeding material for the duration of the growing season and productivity of using a selection index. Methods of researches: hybridization, selection, field and laboratory researches, production test, statistical analysis. Basic results of researches: іn F1 hybrids of soybeans for the duration of the growing season often observed dominance of fast- form ( 5 cases ), followed by an intermediate type of inheritance (4), at least - the dominance of late forms ( 2) and heterosis - in only one case, the mass of the plant and seed traits that lead to plant productivity (number of seeds per plant , number of pods per plant and the number of productive units per plant ) in most cases manifested heterosis , by weight of 100 seeds small heterosis observed only in three hybrids ( Angelica / № 427, Angelica / Maheva, Ustya / Vision ), in other cases, the domination of hybrids manifested greater or lesser weight of 100 seeds , intermediate or her inheritance. In 2011, the state quality testing continued study of ultra- ripening varieties of soybean Siverka, in the competitive strain testing was the best number 375-06, which for the duration of the growing season 98 days, seed yields 3.5 t / ha higher than standard Ug -30 0.85 t / ha and № 182-09, respectively 96 days, 3.06 t / ha and 0.41 t / ha , № 415-06 - 104 days 2.98 t / ha and 0.33 t / ha and № 445 - 96 days, 2.97 t / ha and 0.32 t / ha.
