摘　　要：采用主-微效基因混合遗传模式,分析了花生抗黄曲霉侵染的遗传规律。结果表明花生对黄曲霉侵染的抗性是由一对主基因和一对微效基因控制。主效基因和微效基因均以加性效应为主,无显性效应。主基因、微效基因加性效应值分别为0.38和0.12。The inheritance of resistance to infection by Aspergillus flavus in peanut was studied in the genetic model of a pair of major genes and minor genes. Genetic analysis showed that the resistance to infection was controlled by a pair of major genes with additive value of 0.38 and a pair of minor genes with additive value of 0.12, and the additive action was important for resistance to infection. 
