摘　　要：以自主选育的优良无性系热研87-4-26的初产期林段为研究材料,对其生长情况,开割率,产量,主性状和副性状进行鉴定。结果表明:热研87-4-26年均干胶含量28.42%,极显著高于对照RRIM600;年株产2.03kg/株,显著高于对照;抗寒性较强,2008年寒害级别仅1.11级,略低于对照;蔗糖含量高,胶乳稳定,高产生理基础好,是极具潜力的无性系,值得进一步跟踪观测。Stands of young tapping rubber trees of Clone Reyan 87-4-26 （Hevea brasiliensis） selected by Rubber Research Institute was observed in terms of yield, dry rubber content, coldhardiness and other physiological parameters. This clone had an annual mean dry rubber content of 28.42%, highly significantly higher than that of the control RRIM 600; yielded 2.03kg/tree/year, obviously higher than that of the control; was more coldhardy with the cold injury scale being 1.11, much lower than that of the control, and; had higher sucrose content and stable regeneration of latex, which is a good physiological back ground. Therefore this clone is a promising clone which deserves continuous tracking and observation.
