Features of the formation of the structure of vegetative mass in white lupine of different directions of use

Abstract

Aim. Determination of features and regularities of the formation of vegetative productivity in collection samples of white lupine for fodder and sidereal uses. Methods. Field, measuring and weighting and mathematical and statistical methods of assessments and analyses. Structural analysis by elements of vegetative productivity was carried out in the phase of shiny beans according to methodical recommendations. Results. 94 samples of white lupine for fodder and sideral uses were analyzed. According to the results of 4-year studies, it was established that sidereal collection samples of white lupine slightly exceeded fodder ones in terms of vegetative mass productivity indicators of 113.2 and 107.7, respectively. The most valuable samples combining increased indicators of the share of beans and leaves in the structure of the vegetative mass with high plant productivity are highlighted. These are fodder collection samples 7011, Makarivsky and 1664, the productivity of plants in which was 123.1; 118.3 and 117.0 g, respectively, and the share of beans and leaves - 68.5 and 67.0% and alkaloids Don, UD0800791, Ell Harrach 4, UD0800906, 6-003 with the share of beans and leaves 67.1-67 .6% and plant productivity – 126.0-144.0 g. Separated sources are recommended for the creation of new varieties of white lupine, green-cut and sidereal directions of use. Conclusions. The selected sources of lupine of white green-cut and sideral uses will serve to expand genetic diversity in the creation of new competitive varieties.
