本文利用数量遗传学方法分析害虫抗药性遗传学特性，比较了３种研究害虫抗药性遗传力的方法，其中同胞分析和亲子回归方法根据遗传力的定义直接估计抗性遗传力，阈性状分析法是根据药剂的选择作用估算出现实遗传力。
In this paper, quantitative genetic methods were used to analyze the genetic characteristics of pest resistance. Three methods to study the heritability of pest resistance were compared. Among them, sibling analysis and parent-child regression were used to directly estimate the heritability of resistance according to the definition of heritability. Threshold analysis It is based on the role of the choice of pharmaceutical estimates of the actual heritability.
