本文应用4个有差异的抗病毒品种按不完全双列杂交配制6个组合,对10个性状的遗传进行了分析,结果表明均符合加性——显性模型。遺传阵列方差(Vr)和协方差(Wr)的估算表明,D82—198带有较多控制抗病等级、单株荚数、单株粒重和完全粒重的显性基因;merit含有控制完全粒率、褐斑粒率和百粒重的显性基因较多。并估算了诸性状的广义遗传力、狭义遗传力和平均显性程度等遗传参数,感病等级和褐斑粒率的广义遗传力分别为97.7％和83.1％。 In this paper, six different combinations of antivirals were used to make six combinations according to incomplete diallel cross. The inheritance of ten traits was analyzed. The results showed that they all fit the additive-dominance model. Estimates of genetic array variances (Vr) and covariances (Wr) indicated that D82-198 had more dominant genes controlling disease resistance, pods per plant, grain weight per plant, and full grain weight; merit contained controls Complete grain rate, brown spot rate and 100 grain weight more dominant genes. The general heritability of genetic traits such as general heritability, narrow heritability and average dominance were estimated. The general heritabilities of susceptible grade and brown speckle were 97.7% and 83.1% respectively.
