摘　　要：国外品种的引进和适应性评价在推动我国橡胶树发展上发挥重要作用。本研究以引进印度尼西亚橡胶树品种热试11-107为材料,参照育种技术规程布置品种比较试验,并对其茎围生长量、干胶产量、产排胶特性、天然橡胶质量等进行综合评价。结果表明:热试11-107开割前年均茎围增粗7.6 cm,开割后年均增粗3.0 cm,速生特性明显;开割前5年平均刀次干胶产量为58.41 g,干胶含量为33.37%,均显著优于对照品种RRIM600;热试11-107品种树皮中乳管列数多,排胶初速度快,堵塞指数低,硫醇含量显著高于对照,蔗糖含量与对照相当,具有良好的产排胶特性,产胶潜力大,且寒害适用能力较好。热试11-107天然橡胶分子量大,灰分含量高,塑性初值高,硫化胶的拉伸强度大,撕裂强度大,物理机械性能好。因此,热试11-107综合性状较好,适应我国植胶环境,可在Ⅰ类植胶区扩大试种。The introduction and evaluation of foreign clones play an important role in promoting the development of rubber trees in China.In order to evaluate the adaptability of Indonesian rubber tree clone Reshi 11-107,the stem cir-cumference growth,dry rubber yield,rubber production and discharge characteristics,and natural rubber quality were examined in the clone trail test,which was arranged according to the breeding technical regulations.The average annual stem girth of Reshi 11-107 increased by 7.6 cm before tapping,and increased by 3.0 cm after tapping,and the fast-growing characteristics were obvious.The average yield was 58.41 g and the dry gum content was 33.37%in the first 5 tapping years,which were significantly better than that of the control clone RRIM600.Reshi 11-107 has a large number of laticifers in the bark,the initial flow rate of rubber discharge is fast,the plug index is low,the thiol content is significantly higher than that of the control,and the sucrose content is equivalent to that of the control.It has good characteristics of rubber production and discharge,better potential for rubber production,and good adaptability to cold damage.Reshi 11-107 natural rubber has large molecular weight,high ash content,high initial plasticity value,high tensile strength,high tear strength and good physical and mechanical properties.In conclusion,the comprehensive cha-racters of Reshi 11-107 are better,which could adapt to the planting environment in China,and could be expanded in the type I planting area.
