The study of genetic potential of pea variety samples of various morphotypes in the Rostov region The result of the breeding work largely depends on proper selection of the initial material: the more diverse and richer it is, the faster it is possible to reach the goals. One of the methods to obtain initial material in plant-breeding is hybridization. The selection of the parental forms for hybridization starts with the study of variety samples of various ecological and geographical origins, their genetic potential. The article presents material on the study of 152 collection peas samples of various eco-geographical origins with leafy of mustachioed and leafy morphotypes. The selection samples have been valued on the following traits: duration of vegetation period, the periods “sprouting-flowering” and “flowering-ripening”, plant height, leaf type, number of nodes per plant, number of beans per plant, number of productive beans per plant, number of seeds per bean, number of seeds per plant, seed weight per plant, 1000-seed weight, seed productivity and protein content in beans. As a result there have been selected 50 variety samples possessing a complex of economic-valuable traits. These variety samples have been suggested for future use in the breeding work as parental forms with positive economic-valuable traits.
