摘要
4个陆地棉品种分做3个抗×感杂交组合,采用加性—显性遗传模型对黄萎病抗性进行遗传研究。结果表明,抗黄萎病性状适合加性—显性遗传模型,抗黄萎病基因之间既有累加作用,也有乘积性作用。3个组合基因的加性效应[d]值均明显大于基因的显性效应[h]值;组合间抗黄萎病性状的狭义遗传力差异较大。
The additivedominant model was used for genetic studies on resistance to verticilium willt in three R×S combinations from 4 upland cotton lines The results showed that: The heredity of resistance character to V wilt was consistent with the additivedominant model There were additive and nonadditive effects Additive effects of genes were obviously higher than that of dominance and narrow heritabilities of resistance to V wilt were considerably different among the experimental combinations
