On the basis of the studies in Eastern Siberia the cultivars and lines suitable for use as donors and acceptors of such important agronomic traits as the absence of the parchment layer and tiered heterophily. In the first generation hybrids in the study of donor tier of heterophily in most cases, heterosis revealed by key indicators of productivity – the number of fertile nodes, pods and seeds. According to the indicator - the number of nodes before the first pod in most cases, depression is detected. When analyzing hybrids on the basis of a parchment-free character in the first generation with the Svetozar variety, characterized by tendril leaf type and smooth seeds, heterosis is revealed. Sample B-478, characterized by leaflet type of leaf and smooth seeds in this case, most of the signs observed depression. In the second generation by the analyzed features the standard splitting in the ratio 3/4:1/4 is confirmed, typical for self-pollinated crops, indicating the independent nature of inheritance of the studied traits. As donors of tiered heterophily it is recommended to use samples TM 06-462, TM 06-257 (Research Institute of Agriculture Northern Zauralye), KT-6455 (Tatar Research Institute of agriculture), Spartak (VNIIZBK). As a donor of the sign of parchment-free of beans, it is recommended to use a sample ТМ 06-462 (Research Institute of Agriculture Northern Zauralye).
