摘要
橡胶树(Hevea brasiliensis)优良品种热研7-33-97具有生长速度快、抗性强、产胶潜力大和干胶理化性能好等优点。为研究热研7-33-97作为杂交亲本选育优良新品种的潜力,分别对热研2-73×热研7-33-97、热研5-11×热研7-33-97、热研7-33-97×海垦1的人工杂交授粉子代进行生长量和产量早期鉴定。结果表明:不同杂交组合子代的茎围生长和产量均有显著差异,热研7-33-97作为父本或者母本均能较好地遗传其速生、高产性状。子代性状的正态分析表明,从热研2-73×热研7-33-97杂交组合子代中选育出胶木兼优品种的可能性较大,从热研5-11×热研7-33-97杂交组合子代中选育出高产品种的可能性较大,从热研7-33-97×海垦1杂交组合子代中有选育出抗风高产品种的可能性。
CATAS 7-33-97 is a rubber tree (Hevea brasiliensis Mull. Arg) clone with characteristics of fast growth, strong resistance, high-yielding potential, good adhesive physical and chemical properties. The girth growth and dry rubber yield of different hybrid of CATAS 7-33-97 was identified in early period. Results showed that there was significant differences in girth growth and dry rubber yield among hybrid; The fast growth and high yield characters of CATAS 7-33-97 can pass to progeny as male and female parent well; The hybrid combination of CATAS 2-73×CATAS 7-33-97 has the potential to select out Latex/Timber clones; The hybrid of CATAS 5- 11×CATAS 7-33-97 has the potential to select out high yield clones; The hybrid of CATAS 7-33-97×Haiken 1 has the potential to select out wind resistance clones.
