Introduction: To study the regularities in the inheritance of quantitative and qualitative traits during hybridization is known to be necessary for improving the effectiveness of the selection process. It should be noted that the possibility of the differentiation of individuals with positive transgressive traits, which do not manifest themselves in F₁ hybrids, decreases in F₂ hybrids. According to some authors, extensive phenotypic variations in quantitative traits occur in the hybrid combinations of the second generation (F₂). As a result, depending on the genetic hereditary factors of the components involved in the hybridization, differentiation of the phenotypic dominance rate in the obtained hybrid combinations was observed [1; 2; 3; 6].
