COMPARATIVE EVALUATION OF THE SAMPLES OF NARROWLEAVED LUPINE WITH REDUCED BRANCHING AND MAIN CHARACTERISTICS OF THE NEW VARIETY YARYK

Abstract

The paper presents the results of the research on the samples of narrow-leaved lupine with reduced branching. The main indices of productivity, seed quality are described as well as morphological traits.
The basic characteristics of the new narrow-leaved lupine variety Yaryk with reduced branching are presented. The potential yield of the variety is 65.8 dt/ha, the content of protein in grain is 33.0-35.0%, the content of alkaloids – 0.023-0.034%. In the state variety testing, the maximum seed yield - 42.6 dt/ha was obtained in 2019 at the Goretskaya variety testing station, on average the seed yield of the Yaryk variety was 27.0 dt/ha at all variety testing stations for three years.
The distinctive feature of the new variety is the duration of its vegetation period: it is more late-ripening than the check variety. On average, over the years of the study, the vegetation period was 89-109 days, which was 14 days later than the check variety from the group of reduced lupine varieties Talant and 2 days shorter than the check variety from the group of varieties Mirtan with ordinary branching.
