摘　　要：湛试327-13是从杂交组合93-114×PR107后代中选育出的一个抗寒高产、综合性状优良的橡胶树新品系。经近30a的连续跟踪和比较试验,该品系平均耐寒性比对照GT1轻1.85级,初级系比区产量比对照GT1高97.7%;而生产性系比区干胶产量极显著高于对照品系93-114,增产168%。湛试327-13适宜在华南沿海植胶区推广使用。Zhanshi 327-13 is a new cold-resistant and high-yielding clone of Hevea brasiliensis, with better combined traits, and was selected from a cross 93-114 × PR107 by the South Subtropical Crops Research Institute （SSCRI） . The clone trials and continuous tracking of this clone have been done for nearly 30 years. Zhanshi 327-13 has a cold resistance level 1.85 higher than the control GT1, and its dry rubber yield was 97.7% higher than that of the control in the primary clone trial, and 168% significantly higher than that of the control 93-114 in the commercial clone trial. This suggests that Zhanshi 327-13 be suitable for planting in the rubber tract in the coastal area of South China.
