摘　　要：对我国1991～1993年全国橡胶树优良品种推荐书推荐品系的表现,并结合马来西亚现推荐的橡胶树优良品种资料,进行比较分析,结果我国目前推广橡胶品种的产量比较高,热研88—13、海垦2、大丰95和云研277—5等4个中推级无性系的产量显著高于 RRIM600。同时,由于主要选用抗风或抗寒杂交亲本,现推广品种的抗风或抗寒能力,都明显增强。但鉴于我国主要植胶区台风较频繁,风害较重,使用的橡胶抗寒品种较单纯,今后还必须挖掘新杂交亲本的潜力,使我国抗风高产和抗寒高产的橡胶品种的培育步上新台阶。A comparative analysis was made of the recommended clones'performances using the data of China Planting Recommendation 1991—1993 as well as RRIM Planting Recommendation 1990—1991.The results show that Hevea clones recommended for current planting give a fairly high yield,especially SCATC88—13,HK2,DF95 and YN277—5 yielding remarkably higher than RRIM600,and possess better wtndfast- ness or cold hardiness due to their parental choice.The potential of new parents selected for crossing should,however,be tapped to speed up development of windfirm and cold hardy high-yielding clones in view of the simplicity of the clones employed for planting in China major rubber tracts which are frequently windslashed causing serious damages.
