摘　　要：2020年春季橡胶树白粉病暴发流行,于白粉病流行末期,在国家橡胶树种质资源圃对Amazon野生种质及Wickham栽培种质进行了抗白粉病调查。结果表明,共调查种质4788份,其中,抗病种质18份,占0.38%,均为Amazon野生种质;中抗种质146份,占3.05%,Amazon野生种质145份,Wickham栽培种质1份;中度感病种质1180份,占24.64%;感病种质2557份,占53.40%;高度感病种质887份,占18.53%。Powdery mildew of rubber tree broke out in the spring of 2020.At the end of the epidemic period,the resistance of Amazon⁃wild germplasm and Wickham cultivated germplasm to powdery mildew was investigated in the national rubber germplasm resource nursery.The results showed that a total of 4788 germplasm were investigated,among which 18 germplasm were disease resistant,ac⁃counting for 0.38%,and all were Amazon wild germplasm.146 medium resistant germplasm(3.05%),145 wild germplasm and 1 Wickham germplasm.1180 moderately susceptible germplasm(24.64%);2557 susceptible germplasm,accounting for 53.40%;There were 887 highly susceptible germplasm(18.53%).
