The article presents research results of sweet pepper breed lines selected as a promising material to solve the problem of creating new varieties of sweet pepper under the conditions of the Lower Volga region. It is necessary to study the various sweet pepper genotypes, select those that stand out for several valuable traits, and study their offspring for use as donors when creating new varieties. During 2020-2022, 54 collection samples were tested, and 29 breeding lines proved to be the best in several ways. This study investigated the maturity duration, fruit weight, pericarp thickness, and fruit color of the selected genotypes. The selected sweet pepper lines are of interest for further breeding work and can be used as genetic sources of valuable traits when creating new varieties under the conditions of the Lower Volga region of Russia.

Key words: Vegetables, sweet pepper, breeding lines, phenology, fruit weight, pericarp thickness, fruit color.
