| 摘 要： | 豌豆白粉病是由白粉菌（Erysiphe pisi D. C.）引起的豌豆最重要的病害之一,控制豌豆白粉病最经济有效且环保的方法是种植抗病品种。在温室条件下对400份豌豆种质资源进行白粉病抗性鉴定,同时利用7个与已知豌豆抗白粉病基因连锁的分子标记进行基因型鉴定。结果表明,在400份资源中,有8份表现免疫,3份表现抗病,5份表现抗感分离,其余384份均为感病;16份抗性资源中有10份来自于四川省中部不同纬度地区,其余6份为国外引进资源;7个分子标记将400份种质资源分为39个标记基因型,其中16份抗性资源分为7个标记基因型。上述抗性资源及其标记基因型可有效应用于豌豆白粉病抗性育种的研究中。

| Abstract: | Powdery mildew caused by Erysiphe pisi D. C. is one of the most important diseases of pea. The most economical, effective and environmentally friendly way to control powdery mildew of pea is to plant resistant varieties. A total of 400 pea germplasm resources were identified for the resistance to powdery mildew under greenhouse conditions. At the same time, seven molecular markers linked to known powdery mildew resistance genes of pea were used for genotype identification. The results showed that among the 400 identified germplasms, eight accessions showed immunity, three accessions showed resistance, five accessions showed resistance-susceptibility separation, and the remaining 384 accessions were susceptible. Among the 16 resistant accessions, ten accessions were from different latitudes in central of Sichuan and the remaining six accessions were imported from abroad. Seven molecular markers divided the 400 germplasms into 39 marker genotypes and 16 resistant germplasms were divided into seven marker genotypes. The resistant resources and their marker genotypes described above could be effectively used for the breeding of pea resistant to powdery mildew. |
