Genetic System Analysis of Stem/Leaf Characteristics in Tumorous Stem Mustard
摘要
Abstract
Three inbred lines with different ratio of stem and leaf were used as parents and devel-oped 2 hybrids. Their genetic systems in stem/leaf ratio of P1,P2,F1 and F2 were analyzed by method of joint segregation analysis of major gene plus polygenes mixed inheritance model.The results showed that the genetic systems in stem/leaf ratio of these 2 hybridized combinations were constructed by one pair of additive-dominant major genes plus additive-dominant-epistatic polygenes (D-O).Heritability of the major genes and polygenes in F2 generations were 60.17%-68.74% and 6.83%-10.23%,respec-tively.The additive effects of the major genes were more important than their dominant effects,and dominant effects showed negative in various degrees in 2 hybridized combinations.关键词
