[Evaluation of the combined ability of triticale and secalotriticum by signs of androgenesis in vitro].
The combining ability of cultivars and strains of triticale and secalotriticum with respect to the characteristics of androgenesis in anther culture has been analyzed (the 6 x 3 polytester design and parental forms). Nonadditive effects of gene interaction have been found to be prevalent in the genetic control of the characters analyzed in plants with the given genotypes. However, the characteristics of androgenesis were the highest in those hybrid combinations in which genotypes with high values of general combining ability (GCA) and positive effects of specific combining ability (SCA) participated. A program of the analysis of combining ability in triticale and secalotriticum is proposed. The program is aimed at detecting hybrid combinations with the best androgenetic capacities and takes into account both additive and nonadditive effects.
