Creation and evaluation of breeding material of grass pea in the conditions of the northern part of the Central Black Earth region

46 collection samples of grass pea (Lathyrus sativus L.) from 6 ecological-geographical groups by a complex of economically valuable traits in the conditions of the northern part of the Central Black Earth region were studied. Variety samples were characterized by a wide variation of the studied traits. It is established that according to the increasing degree of variability the main elements of the structure of the seed productivity of grass pea are arranged in the following order: number of seeds in the bean; weight of 1000 seeds; harvest index; number of productive nodes; number of beans per plant; weight of beans per plant; number of seeds per plant; seed weight per plant. The variety samples that showed the highest yields during the years of study have been identified - from 5,0 to 5,8 t/ha: Central European group - k-1702 (France), k-1200 (Bashkiria), k-1707 (France), k-1211 (Tataria), k-1209 (Tataria), k-615706 (Ukraine); Anatolian group - k-1229, k-1215, k-1228 (Azerbaijan). A new variety of grass pea the Slavyanka, characterized by high yields, has been created and submitted to the State Register.
