摘 要 ：对“农业部景洪橡胶树种质资源圃”（云南景洪）保存的290份魏克汉种质资源进行了亲子系谱分析。结果表明，无性系GT1、PR107、PB86、RRIM600、云研277-5、PB5/51、IAN873的后代为210份，占72.41%。从表型看，魏克汉种质资源群体变异丰富，实际上遗传基础很窄。本文以GT1、PR107、PB86、RRIM600、云研277-5、PB5/51、IAN873为主线建立了亲子系谱图，并对部分种质资源的性状进行了分析，获得一些性状的传递遗传规律，供育种工作者参考。

Abstract:The pedigree of 290 accessions of Wickham germplasm resources, preserved in the Germplasm Repository of Rubber Tree (Hevea spp.) JingHong City, Ministry of Agriculture, was analyzed. The results showed that 210 accessions were the offspring of rubber clones GT1, PR107, PB86, RRIM600, Yunyan277-5, PB5/51 and IAN873, which accounted for 72.41% of all 290 germplasm resources. Wickham germplasm resources had abundant population variances on phenotype, but actually had very narrow genetic basis on genotype. In this article, the family trees were set up mainly based on the rubber clones GT1, PR107, PB86, RRIM600, Yunyan277-5, PB5/51 and IAN873, and characteristics of some germplasm resources were analyzed. The Genetic regulation of hevea brasiliensis was sought out and it can provide reference for rubber breeders.
