Modular organization of quantitative signs in vetch (Vicia villosa Roth) genotypes

Viliana Vasileva and Valentin Kosev

The above-ground plant material and root mass of eight winter vetch genotypes (Vicia villosa Roth) varieties were studied. As a method of study and evaluation, the ecological and genetic models for the organization of the quantitative trait and the method of orthogonal regressions were applied. The study was conducted in 2014-2016 in the experimental field of the Institute of Forage Crops, Pleven, Bulgaria. The highest and most stable seed yield was obtained at BGE001847 (87.69 kg /da), followed by BGE000643 (77.51 kg/da) and BGE004222 (72.42 kg/da). BGE000639 and Asko 1 were characterized by high variability and low seed yield (28.30 kg/da, 54.28 kg/da). The highest yielding and most stable in relation to green mass were varieties BGE000643 (3736.32 kg/da) and BGE001847 (3206.33 kg/da). Strong genes of physiological systems attraction and adaptability by fresh aboveground and root mass weight have been identified as BGE000637, and varieties BGE000639, BGE000643, BGE001383, Asko 1 and BGE004222 had good adaptation by seeds weight per plant and root mass weight. Due to the high productive capacity of seed and green mass, as well as the high root mass weight, these patterns represent a particular interest for the needs of combinatorial breeding
