摘　　要：RRIM600是20世纪在中国轻寒区大规模推广种植的国外优良橡胶树高产品种,由该品种衍生的热研7-33-97和文昌11已在海南、广东等植胶区大规模推广种植,成为更新胶园的主推品种,热研88-13成为培育高产无性系的重要亲本。为探讨RRIM600作为亲本在中国橡胶树育种上的利用价值,本文分析了该品种在中国推广种植的适应性、农艺性状表现、刺激割胶生理效应、主要衍生品种的品种特性等。结果表明:RRIM600开割前后茎围生长均较快,单位面积产量高,刺激割胶可提高产量,但应注意刺激浓度和频率。以RRIM600为亲本,通过不同育种方法,育种工作者先后育成了热研7-33-97、热研8-79、热研88-13、文昌11等试种级以上品种54个,这些品种都保持了RRIM600的高产特性。因此,RRIM600是一个高产的橡胶树优良亲本,对中国选育高产橡胶树新品种有重要的利用价值。RRIM600 is a rubber clone with high yield, recommended for large scale commercial planting in mild-cold areas and introduced from aboard. The Reyan 7-33-97 and Wenchang 11 derived from RRIM600 were large scale commercial planting as main recommended clones for renewal rubber plantations in Hainan and Guangdong. Reyan 88-13 derived from RRIM600 has important value for developing the new rubber clones with high-yielding. In order to explore the value of RRIM600 as a crossing parent in rubber breeding program, the adaptability, economical character, stimulated tapping system and physiological status of RRIM600 were analyzed, meanwhile the main features of its several derivatives were also described. The results showed that RRIM600 faster grow and high yield, stimulated tapping can improving yield but must take care the systems. As a parent, the 54 clones such as Reyan7-33-97, Reyan 8-79, Reyan 88-13, Wenchang 11 and others were developed by various breeding methods,and all these derivatives maintained its excellent traits such as high and stable yield. Therefore, it was concluded that RRIM600 was an elite parent with high yield, and it had important value for developing the new rubber clones with high-yielding.
