Correlation of seed and vegetative productivity elements in collection samples of white lupine
A. Golodna | T. Baidiuk
The purpose of the study was to establish the strength and general pattern of correlations between quantitative traits that form vegetative and seed productivity in white lupine. Research methods used included field, weighing and measuring, and mathematical and statistical methods. A significant positive correlation was found between the average strength of seed productivity and such traits as plant height, number of lateral shoots, number of beans from central and lateral clusters, etc. A strong positive correlation was detected with the vegetative development of plants, and a weak one with the number of seeds per bean and the weight of 1000 seeds. A significant strong positive correlation of vegetative productivity with such quantitative traits as the weight of beans from the central cluster and the weight of leaves and stems was established. A positive correlation of average strength was found with the number of beans from central and lateral clusters, weight of beans from lateral shoots, root weight, etc. It was found that the seed productivity of white lupine plants is mainly conditioned by the development of such traits as the number of beans from lateral clusters, weight of leaves and roots, number of seeds and weight of seeds from the central and lateral clusters. The formation of vegetative productivity primarily depends on the weight of beans from the central cluster and the weight of leaves and stems. The use of the established regularities of productivity formation will enhance the effectiveness of the selection of selective material according to the specified parameters
