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。本研究以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。
290 pedigree germplasm resources of Weikehan germplasm conserved in Jinghong rubber tree germplasm resource garden (Jinghong, Yunnan) were analyzed by pedigree genealogy. The results showed that the progenies of clones GT1, PR107, PB86, RRIM600, Yunyan 277-5, PB5 / 51 and IAN873 were 210, accounting for 72.41%. From the phenotype, Weikehan germplasm resources vary widely, in fact, the genetic basis is very narrow. In this study, we established a pedigree pedigree with GT1, PR107, PB86, RRIM600, Yunyan 277-5, PB5 / 51 and IAN873 as the main line, analyzed the traits of some germplasm resources, For breeding workers for reference.
