Correlation dependence of selective valuable traits of yellow lupine

Abstract

As a result of the conducted study, it was found that the combinations of crosses 16-20, 22-20 and 24-20 with dominance in F1, transgression in F2 on biologically valuable traits in selective respect in F3 confirm their correlation relationship and differ in the type of utilization. The 16-202c hybrids are seed oriented due to high plant survival rate and high number of beans on the main raceme. The material of hybrids 16-204v, 22-202c, 24-202c is universal, characterized by high productivity, which is confirmed by the correlation with the number of seeds and their weight (by grain), with the height of the remaining plants to harvesting, the number of beans on them and lateral branching (by herbage). The analysis of pairing of economically useful traits on seed productivity revealed a positive relationship between the number and weight of seeds from the main inflorescence in combinations 5-202c (r = 0.74 and 0.82), 22-20 (r = 0.89 and 0.92), 24-20 (r = 0.80 and 0.71), 30-20 (r = 0.94 and 0.93) and others. High correlation was found between the grain yield and the number of surviving plants to harvest in hybrids 5-202c (r = 0.92), 30-202c (r = 0.83), 6-202d (r = 0.73), 22-20 (r = 0.79), 24-20 (r = 0.80). Regardless of the combination of crosses, the number and weight of seeds from the main inflorescence with the correlation coefficient from 0.71 to 0.93 have a strong positive effect on the seed productivity of most hybrids. A positive effect was obtained from the number of beans from the main raceme in combinations 17-202c (r = 0.90), 25-202c (r = 0.81), 24-20 (r = 0.77), and 5-202c (r = 0.90). The herbage yield of yellow lupine was influenced by the plant height (r = 0.61–0.93), the number of surviving plants to harvest (r = 0.51–0.95), the presence of lateral shoots with beans (r = 0.54–0.63) in hybrids 5-202c, 16-202c, 22-202c, 24-202c and others.
