摘　　要：用几率值分析法和浓度(对数)—死亡率几率关系曲线法,研究家蚕对NPV病毒经口感染的抵抗性遗传规律。结果显示:家蚕对NPV病毒经口感染的抵抗性遗传方式受一对主效基因和若干微效基因控制;杂交后代(F1、F2)对于该病毒的抵抗性有偏父遗传现象,杂交一代的抗病性表现出杂种优势。The study on the inheritance of Nuclear Polyhedrosis Virus （NPV） resistance in Bombyx mori that infected by peroral was carried out based on probit analysis method and curve analysis between density of NPV （logarithm） and the death ratio. It can be indicated from the results that the inheritance of NPV- resistance controlled by a major dominant gene together with many minor genes. The F1 and F2 progeny show patrolclinal tendency in NPV- resistance inheritance and F1 shows heterosis.
