For elite seeds, mother clones were selected; productive genotypes were singled out. Best results were obtained with a big amount of source material (15 - 40 clones) able to embrace most genotypes. When a small number of plants had been selected, we observed significant varietal changes and inbreeding depression. Seed-formation abilities of various pollination types (spontaneous pollination and cross-pollination) were assessed. Best results were obtained in case of cross-pollination - 5.38 seeds per fruit; in case of self-pollination the result was 0.16 seeds per fruit with inbreed depression observed after 2 - 3 generations. Based on the research results, recommendations on cultivation of new synthetic Lotus corniculatus varieties for the fodder purposes are currently being developed with the use of self-incompatibility. Synthetic heterosis Lotus corniculatus populations obtained by hybridization of 15 - 18 high-production clones showing good combinability are undergoing industrial tests.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
