Its realization largely depends on significant indicators of individual productivity: quantity increase of productive nodes, beans in a node, quantity of seeds in a bean, seed size. Based on the criteria of field- and laboratory assessment, the traits indication analysis was given of productivity and plants resistance to adverse environmental conditions of collection samples, selection numbers, soya production varieties in order to select the source material when creating new varieties which are adapted to biotic (pathogen-resistance) and abiotic (cold-resistance) factors. New soya lines were created as the result of purposed pairs selection for crossing and hybridization performance. At lines creation, selection samples were included of various ecologic-geographical origin, which increased the probability of the most favorable combinations. The basic traits by which the sample varieties were selected for crossing – yield capacity, precocity, diseases-resistance, adaptability to mechanized harvesting (lodging-resistance, the lower bean high attachment). In competitive variety test, the selection numbers were extracted, which at vegetation period duration 109-127 days, seed yield capacity level 2,15-2,34 t/hа have exceeded the standard (variety Vasylkivska) by 0,14-0,27 t/hа. The advanced samples had a plant height 77,1-89,5 cm. The lower beans attachment height made 11,2-15,1 cm. The weight of 1000 grains of the best samples investigated was within 149-168 g.
