摘　　要：花生网斑病严重影响花生的产量和品质。为探究花生网斑病抗性遗传机制,本研究利用植物数量性状主基因+多基因混合遗传模型对感病品种豫花22和抗病品种冀农99杂交得到的F2:3群体进行了网斑病抗性遗传分析。对病斑面积比和病情指数的分析结果表明,花生网斑病抗性主要由1对主基因加性-显性效应控制,主基因遗传率分别为76.72%和65.45%,一对主基因加性效应值(da)分别为8.11和21.95。本研究可为花生网斑病抗性育种提供一定的理论基础。Web blotch is one of the most important diseases in peanut,which seriously affected the yield and quality of peanut.To explore the genetic mechanism of peanut web blotch resistance and to facilitate breeding resis-tant peanut cultivars,the major gene plus polygene mixed inheritance model was applied to analyse the genetic mod-el of peanut web blotch resistance in the F2:3 populations derived from the cross between Yuhua 22 and Jinong 99.Results indicated that the resistance to peanut web blotch followed the one major gene of additive-dominant model.Under this model,the heritability of lesion proportion and disease index were 76.72%and 65.45%respectively,and the additive effect values(da)of the major gene was 8.11 and 21.95 respectively.The study provides a theoretical ba-sis for breeding resistance peanut variety to web blotch.
