Analysis of the results of selection of yellow lupine of universal use type showed that in F1 plants were obtained the degree of phenotypic dominance of which over the average value of parental forms was noted by height in 3 combinations (1.0–4.3 times), by the number of beans on the main peduncle in 6 — by 1.0–4.4 times and total beans in 15 by 1.0–10.5 times. Dominance by three main elements of the structure was revealed in combinations 17-20 and 22-20. In F2 hybrids the effect of stable increase in plant height was observed in seven hybrids with transgression of 7.1–23.6% and its frequency of 3.2–18.2%, by the number of beans on the main brush in 11 samples and the total number on the plant in 12 with transgression fluctuations from 9.5 to 37.8% and from 8.6 to 60.0% and the frequency of occurrence of such plants of 2.0–10.8% and 3.0–16.2%. In terms of grain yield (363–400 g/m2) and green mass (5.55–5.75 kg/m2) on average over two years of research (2023 and 2024), the universal hybrids 11-20-522c, 22-20-204d and 17-20-164v stood out, exceeding the best parental forms by 60–150 g/m2 and 0.40–0.60 kg/m2, respectively. Hybrids 16-20-174v and 24-20-1552c are more productive in terms of green mass: 5.95 and 5.85 kg/m2, and 3-20-382a in terms of grain yield: 375 g/m2.
