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Helicoverpa armigera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0.2476±0.0248,体重遗传力为0.3613 ± 0.1299;抗性与其母体效应无关;抗性与体重之间存在显著的遗传负相关。

Abstract: 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 tolerance, but affected the larval weight. The genetic correlation between larval weight and the tolerance to cyhalothrin was significantly negative(ra=-0.3416±0.1185,P<0.01).
