The results of studying 145 collection soya samples of different ecological- geographic origin in the Left Bank Forest-Steppe of Ukraine were presented in the article. The polymorphism of collection soya samples as to the duration of vegetation period and inter-stage period of “sprouts-blossoming” was established. The results of distributing the samples into groups show that among the investigated genotypes of soya the samples of early maturing group prevailed. The forms, combining lodging resistance, pod splitting resistance at ripening, and having a high attachment of lower pods, were also found. Several samples characterized by the complex of economically valuable signs, such as productivity, the weight of 1000 seeds, number of pods, and number of seeds in one plant, were singled out. It is expedient to use the given samples for further selection work and attract them to the selection programs of creating highly productive varieties.
