title: [Inheritance analysis of resistant starch content in kernels of wheat].
abstract: In this study, three wheat (Triticum aestivum L.) cultivars with high and low levels of resistant starch contents each were selected to obtain 15 F1 combinations from a diallel cross without reciprocals to be used to study the inheritance of resistant starch content. The results of this study are useful to select new wheat cultivar with high level of resistant starch content. Annong 90202 and D68-20 were the best among the wheat cultivars tested for general combining ability of resistant starch content, which significantly increased the resistant starch content in its progenies. The specific combining ability of Annong 90202 x 04 Dan 28 and 06-5 x D68-20 were the best among the F1 combinations, and the values of specific combining ability effects were significantly higher than other combinations. The inheritance of resistant starch content fitted the additive-dominance model, and the degree of dominance was super dominance. The alleles for increasing resistant starch content were recessive. The distribution of alleles for increasing and reducing resistant starch contents in the parental lines was not even. The number of recessive alleles for resistant starch content was greater than the dominant alleles. Annong 90202 and 04 Dan 28 had more recessive genes controlling resistant starch content, while Ningchun 18 and Xinchun 5 had more dominant genes. The narrow sense heritability of resistant starch content was 36.49%.
