This article deals with the evaluation of new pea breeding lines. Current research is relevant because of less plant protein production. Peas, with a high protein content and an optimal amino acid balance, could help to solve that problem. The research is devoted to a comprehensive assessment of new pea lines productivity to identify the best varieties for further breeding. As a result, after evaluating the new lines across two generations, 19 lines were identified based on the number of beans per plant, forming from 8 to 9 beans; 18 lines – based on the number of seeds per plant, forming from 41 to 50 seeds; 15 lines – based on the number of seeds per plant, yielding between 6.5 and 8.5 g. The PP-104, PP-156, and PP-167 lines were observed as most valuable for breeding with high productivity. Selected most pea productive lines are intended to use in testing nurseries to develop new high-yielding pea varieties.
Keywords: pea breeding, productivity, beans, seeds, selection, lines.
