Breeding value of white lupin varieties

Abstract

The breeding value of white lupin specimens was studied and the effect of the environment and genotype on some characteristics has been demonstrated. The role of the genotype was found the strongest for the nodulating ability of the plants. The genetic variance was within the range of 0.001 (the specific nodulating ability) to 29.16 (the number of leaves per plant), and the phenotypic variance of 0.001 (the specific nodulating ability) to 43.15 (number of leaves per plant). High genetic advance in combination with high inheritability was obtained for the number of leaves per plant (3.56, 67.58%), stem fresh weight (2.81, 68.24%) and aboveground fresh weight (1.25, 88.05%). High inheritability with low genetic advance was established for the specific nodulating ability (80.81%, 0.09) and the stem dry weight (62.60%, 0.31), indicating the involvement of no-additive gene action. The aboveground fresh weight is positively correlated with: the leaf fresh weight (r = 0.897), the leaf dry weight (r = 0.881), the plant height (r = 0.587) and the dry weight of the roots (r = 0.569). The established genetic diversity in the studied varieties allows for a targeted selection of parental forms and their inclusion in crosses on the different breeding directions.
