Correlation of elements of seed and vegetative productivity of collective samples of white lupine

Abstract

The aim of the study was to establish the strength and direction of the correlations between the quantitative traits that form vegetative and seed productivity of white lupine. Field, measuring-weight and mathematical-statistical research methods were used. A significant positive correlation of the average strength between seed productivity and such traits as plant height, number of lateral racemes, number of beans from the central and lateral racemes, etc. was established. A strong positive correlation was found with the vegetative development of plants, weak - with the number of seeds in one bean and the weight of 1000 seeds. A significant positive strong correlation of vegetative productivity with such quantitative features as the mass of beans from the central racemes and the mass of leaves and stems was established. A positive correlation of medium strength was found with the number of beans from the central and lateral racemes, the mass of beans from the side racemes, the mass of roots and so on. It was found that the seed productivity of white lupine plants is mainly due to the development of such traits as the number of beans from the lateral racemes, the weight of leaves and roots, the number of seeds and the weight of seeds from the central and lateral racemes. The formation of vegetative productivity primarily depends on the mass of beans from the central racemes and the mass of leaves and stems. The use of established patterns of productivity will help increase the effectiveness of selection of breeding material for the specified parameters.
