Abstract
Plant material from aboveground biomass of 53 samples of pea different originated was analyzed during two consecutive years. The ecological-genetic model for the organization of the quantitative traits and the method of orthogonal regression were used. The following characteristics were studied: number of unproductive nodes per plant, number of productive nodes per plant, total number of nodes per plant; number of pods per plant, weight of pods per plant (g), weight of one pod (g), number of grain (green) per plant; weight of grains per plant (g), weight of one grain (g) and number of grains per pod. Mira, Marsi and Lincoln were distinguished by a larger total number of nodes per plant and a larger number of productive nodes per plant. Marsi (69.18 g), Lincoln (54.63 g), Izomrud (53.52 g) and Paldin (52.93 g) formed a larger number of pods in good combination with the weight of one grain per plant. Mira (105.50), Marsi (101.83), Vyatovo (97) and line 1855/3 (78.50) were distinguished by a large number of grains per plant, and Marsi (38.80 g), Izomrud (25.88 g), Mira (24.92 g), Puldin (24.38 g) and line 101i (24.22 g) had the highest weight of grains per plant. Lincoln, Marsi, Vyatovo and Mira were of interest and can be included in future hybridization schemes to obtain forms combining in one genotype a larger number of fertile nodes and a high weight of grains.
