| 摘 要： | 为了提高橡胶树的抗灾能力,从1979年起在海南岛中部属偶发性重风微寒区的黎母岭山区,开展了组配抗逆高产的橡胶三合树的研究。经九年验证,选配出的GTI/PR107组合品系1—4割年平均亩产干胶51.6公斤,为对照无性系PR107的129％,开割率达83.2％,保存率达96.2％,已被评定为小规模推广等级;组配的GT1/RRIM600、GT1/RRIM623、GT1/PB/63、大岭485/RRIM600和大丰359/GT1等具有抗逆高产性状,是有希望的组合品系。

| Abstract: | Rubber Plantations on Lima Ridge in Central Hainan Island fall in the sporadic severe wind-lashed but mild cold-ridden region, where typhoons, radiative cold damage and leaf diseases dilapidate the presently-recommended Hevea eultivars. A programme for selection and forming of three-part-tree combinations with desirable yielding capability and stress tolerance was conducted since 1979 to enhance the stress tolerance to natural hazards of Havea clones. The resultant combination GT1/PR107, which is higher in tapability (83.2%),greater survival rate(96.2%) and mean yield over the first four years of tapping reaching 774.0 kg/ha/yr as 129.6% of the control clone PR107, has been recommended for small scale planting; other combinations, eg. GT1/RRIM600, GT1/RRIM623, GT1/PB5/63, Daling485/RRIM600 and Dafeng359/GT1 are very promising combinations with desirable characters such as high yielding and better resistance. |
