Current research is devoted to pre-selection of parental pea plants. Assessment of pea plants was carried out according to the main quantitative options in the frame of the plant productivity. The following indicators were evaluated: “number of beans per plant”, “the number of seeds per plant” and “pure mass of seeds per plant”. Only samples with positive standard deviation from the mean value were selected for further breeding. The research is aimed at selection of parental pea plants by the main quantitative options, based on the established criteria using variation statistics methods. Assessment of parent pea plants from the hybrid population F5 by the main quantitative options made it possible to select samples with the criteria: by the number of beans per plant –145 samples or 59% of the total sample; number of seeds per plant – 56 samples or 23% from the total sample; by weight of seeds per plant – 107 samples or 44% from the total sample. The most efficient samples for breeding were PP-72, PP-15, PP-3, PP-4, PP-173, PP-197 with high values for all quantitative options examined. These pea plants represent transgressive forms and account for 2.5% of the total sample. The selected parent pea plants are recommended to use in further researches for obtaining new lines in pea breeding.
