摘要
利用数量遗传学方法和半同胞交配设计 ,测定了棉铃虫Helicoverpaarmigera对三氟氯氰菊酯抗性和体重的狭义遗传力 ,并分析了棉铃虫抗药性与其体重之间的相关性。结果表明 ,棉铃虫对三氟氯氰菊酯的抗性狭义遗传力为 0 2 4 76± 0 0 2 4 8,体重遗传力为 0 3613± 0 12 99;抗性与其母体效应无关 ;
The narrow sense heritabilities of larval tolerance to cyhalothrin and larval weight, and the genetic correlation between larval weight and tolerance to cyhalothrin in \%Helicoverpa armigera\% were evaluated using a half\|sibling design of quantitative genetics methods. The results showed that narrow sense heritabilities were 0 2476±0 0248 for tolerance to cyhalothrin and 0 3613±0 1299 for larval weight in the cyhalothrin\|resistant strain. The maternal factors did not associate with the resistance tole...
