Assessment of white lupine collection using integrated evaluation indices on the manifestation of signs of productivity, seed quality, and green mass

Abstract

Goal. To assess genetic diversity and to select collection specimens — sources of valuable traits of white lupine based on the use of indices of distance from the adaptive norm. Methods. Field, laboratory, measuring-weighing, mathematical and statistical. The integrated assessment was performed based on the application of indices of distance from the adaptive norm, which showed the distance from the average collection phenotypic value for different valuable features of each sample. Results. According to the development of the vegetative sphere, 10 non-alkaloid and 10 alkaloid collection samples with a high value of integrated assessment indices (>1.06) were the best, while according to the development of the generative sphere (>1.04) — 11 non-alkaloid and 10 alkaloid samples were the best. Samples with a high integrated rate differed in the level of manifestation of individual traits. Samples of fodder use compared to sidereal differed more in plant height, increased number and weight of beans from the lateral tufts, and were inferior in value to the indices by weight of leaves, stems, and yield of green mass. According to the development of the generative sphere, fodder and green manure samples had similar values of integrated assessment indices. Non-alkaloid samples were inferior to sidereal in number and weight of seeds from the central brush, but significantly exceeded the content of protein and oil in the seeds. Conclusions. According to the high value of the indices of integrated assessment of the development of the vegetative sphere, the best fodder samples were: 825/10, 7793, 7760, Makarivskyi and Chabanskyi (1.11–1.18); and the best green samples were: UD0800554, Population, UD0800791, Ell Harrach 4 and Don (1,15–1.30). According to the results of the assessment of the development of the reproductive sphere, the highest values of integrated indices had feed samples 1641, August, Degas (1.07–1.12), and green samples UD0800895, UD0800791, Don, Ell Harrach 4 (1.10–1.16).
