摘　　要：1986年引进海南大丰农场培育的橡胶树优良品种大丰95,在云南建立生产性适应系比试验区,通过29年的生长量、产量、副性状、抗性观测结果表明:大丰95幼树生长快,可提早开割,产量中等,抗寒能力与对照GT1相当,抗白粉病能力与对照RRIM600相当,干胶含量较对照RRIM600高,死皮发病指数较对照RRIM600低,刺激效应差,但耐刺激,为二类刺激品种。Excellent rubber tree variety Dafeng 95,cultivated by Dafeng Farm,Hainan,was introduced in Yunnan in 1986 to establish a clone trial area of productive adaptability.After persistent observation of growth,yield,side characters and re-sistance identification for 29 years,the results showed that,the saplings of Dafeng 95 grew fast,with earlier tapping and medium yield,which indicated a comparable cold resistance with the control GT1,a comparable powdery mildew resis-tance with RRIM600(control),a higher dry rubber content than RRIM600 and a lower index of TPD(tapping panel dry-ness)than RRIM600.The stimulation effect appeared poor,but resistant to stimulation,which is the second stimulation va-riety.
