Objective: develop methods for evaluating soybean starting material using a selection index and middle-grade intensive type adaptive to stressful environmental factors. Research methods: hybridization, selection of plants, field and laboratory research, production testing, statistical analysis. Main research results:to improve methods for assessing the breeding material offered "morphological index", which in the reporting year was positive at 1% accurate correlation with level indication seed weight per plant r = 0,26291 and the number of seeds per plant - r = 0,330477. In the contest was the most productive strain testing a new variety of soybean Constellation, which for the duration of the growing season 121 days, the level of seed yield 3.53 t / ha higher than standard Kiev 98 by 0.71 t / ha and breeding numbers in which the level of seed yield and its gain over the standard respectively were as follows: 677-10 (3.47 and 0.64 t / ha), 612-10 (3.42 and 0.59 t / ha), 521-10 (3.37 and 0.54 t / ha), 435-10 (3.31 and 0.48 t / ha), 604-10 (3.29 and 0.46 t / ha), 825-10 (3.25 and 0 4 t / ha), and 423-10 (3.19 and 0.37 t / ha). strain testing in the preceding distinguished: № 611-10, which for the duration of the growing season 136 days, seed yields of 3.25 t / ha exceeded the standard Kiev 98 to 0.28 t / ha, № 408-10 under 121 days, 3.35 and 0.37 t / ha and № 614-10 - 112 days 3.19 and 0.22 t / ha; were better in the control room: № 739, which for the duration of the growing season of 130 days, the level of seed yield 4.02 t / ha exceeded the standard by 1.52 t / ha and others. Selected significant number of breeding numbers with given parameters in hybrid breeding and nursery.
