Abstract:

Based on a survey about rubber industry development in three major rubber planting provinces Hainan, Yunnan and Guangdong, this paper briefly expounds the role of science and technology in promoting breeding and extension of rubber tree varieties. It also discusses and analyzes issues of rubber tree breeding and variety extension facing rubber industry development, such as too unitary cultivar,  weak ability to resist natural disaster, tardiness in extending new variety, unsatisfactory breeding for native applicable variety, low accuracy of early predicting technology, poor creation and utilization for germplasm resources, lacking of effective genetic transformation system, etc. Before ending, the paper puts forward suggestions for future research.

Key words: brazil rubber tree (Hevea brasiliensis), industry upgrading, key technology, breeding and selection, extension, suggestion

摘要：

通过对我国海南、云南、广东三大植胶区橡胶产业发展情况的调研,简要阐述了科技对橡胶选育种及推广的推动作用。探讨分析了橡胶树品种选育及品种推广选用方面产业发展所面临的问题,包括:栽培品种单一,抵御自然灾害整体抗逆能力不强,自主选育的新品种推广应用缓慢,本地适应性育种及品种选用工作难于满足生产发展,橡胶树早期性状综合预测技术预测准确性不高,种质资源创新利用进展不快,高效遗传转化技术体系仍未建立等,并对今后的工作提出了建议。
