Using the method of "seeding" hybrid populations of vegetable peas, investigate the effect of selection in later generations F6 and F7 on the variability of the sign "the number of seeds per plant". Methods: general scientific - analysis and generalization of scientific provisions; planning - development of methodology and technology of experiments; field - laying of experiments, phenological observations, morphological description of plants; laboratory - biometric measurements, structural analysis of breeding material, variational statistics - establishment of patterns of variability and reliability of the obtained results. Results. The technique of studying the effect of selection on the basis of the number of seeds per plant has been developed. Selection results from hybrid pea populations of vegetable Pisumsativum L. of later generations F6 and F7, Stop / Trinket combination, are shown. The population level of the F6 population obtained by transplanting was established without selection. The variability parameters of the trait of this population and the level of variability of the parent varieties Stop and Trinket were determined. A comparative analysis of the indicator of the population trait is conducted to the mean of parents and to the best of them. By means of similar comparisons, the influence of selection on the trait of the population F7 obtained from the results of the first selection was proved. A positive result was recorded - the advantage of the studied trait in comparison to the average parents, to the best of them, as well as to the population before the selection. Twofold selection has been proven effective in improving the trait (increasing the number of seeds per plant and reducing variability) in the final population, F9. Conclusions. Thus, the results of double selection on the basis of the number of seeds per plant in the later hybrid populations F6 and F7 achieved a positive result. The final F9population outperformed the average by 33.5%, the best among them by 13.2%. It proved to be the most homogeneous (aligned). The coefficient of variation decreased by 28.9% compared to population before selection (F6), by 19.7% to population F7 (result of first selection), and to each parent by 6.5 and 9.6% , respectively. Therefore, in the selection of this, one of the most variable features of the productivity of vegetable peas, it is advisable to use the method of sowing. To achieve a breeding effect, that is, to obtain a high-yielding and more stable starting material, one or a maximum of two selections in populations of later generations with high homozygosity is sufficient.
