摘要
利用高产、抗寒力强的亲本进行有性杂交，通过抗寒前哨苗圃抗寒性的选择和初级系比、高级系比，以及生产性试验系统资料的鉴定，云研７７—２和云研７７—４在生长、产量、抗性等方面优于ＧＴ１，特别是云研７７—４抗寒能力强。推荐在云南省西部植胶区的重寒区中规模种植；东部植胶区中寒区试种。
Yunyan 77-2 and Yunyan 77-4 which were selected with sexual hybridization utilizing anticold and high-yield parent were proved that are better than GT1 on growth,yield,resistibility by primary clone trial,high clone trial and commercial planting.Yunyan 77-4 is better on cold resistance.It was recommend that Yunyan 77-2 and Yunyan 77-4 were planted on moderate on heavy cold injury stand in west rubber stand and experimental planted on moderate cold injury stand in east rubber stand of Yunnan.
