Use of methods of intervarietal and sortoline hybridization and selection according to the selected list of selection traits to create drought-resistant soybean varieties: early ripening (not more than 100 days), weight of 1000 seeds (more than 130 g), intensive pubescence, drought resistance assessment in sucrose solutions with atmospheric pressure 7 atmospheres with sprouted 61-80% of germinated seeds) and in field experiments (drought resistance not less than 8 points); allowed to create economically valuable forms and new varieties of soybeans resistant to abiotic factors with highly productive properties. The selection process for all nurseries was carried out, the selection value of the best samples was determined. The group with high resistance to drought in terms of sucking power of seedlings includes 4 collection samples of soybeans: Gali, Deni, Ranok, Slavia. Stable identification features for selection description in conditions of critically low humidity were determined: "plant: color of pubescence of the main stem", "leaf: size of lateral leaf", "leaf: intensity of green color", "flower: color", "bean: intensity of brown color" "," Seeds: the main color of the shell ". Varieties and standards of manifestations of the above-listed signs in arid conditions are selected. Two soybean varieties have been created in five years: Kapriz and Duel. Variety Kapriz belongs to the group from very early to early (90-95 days), has a seed yield of 2.0-2.3 t / ha. Weight 1000 pcs. seeds 129-150 g. Protein content - 38-39%, fat - 21-22%. The variety has a high adaptive potential and resistance to arid conditions. Variety Poyedynok belongs to the early group (100 days). According to the results of the experiment, the new variety has a potential yield of 2.0-2.5 t / ha, which exceeds the standard by 0.6 t / ha, with an oil content in the seeds of 21%, p Product Description popup.authors Boyko Konstantin Ya.
