对金沙江干热区麻疯树生物特性、开花特性、结实特性进行观测,并开展不同地理种源麻疯树杂交育种试验。结果表明,麻疯树在本区域生长发育较好,可持续开花结果至1月初,雌雄花比例可达1∶10左右。通过麻疯树杂交育种试验,研究了麻疯树雌雄花分辨、雌花可授粉时间、套袋材料及去袋时间等特性。通过对金沙江干热区麻疯树主要特性和杂交育种技术试验研究,有利于提高育种效果,加速育种进程,提高育种工作的预见性。
The biological characteristics, flowering characteristics and seed-setting characteristics of Jatropha curcas in hot and dry area of Jinsha River were observed, and the experiment of Jatropha curcas hybrid breeding with different geographical provenances was carried out. The results showed that Jatropha curcas growth and development in the region better, sustainable flowering results to early January, the ratio of male and female flowers up to 1:10 or so. By Jatropha curcas hybrid breeding test, Jatropha curcas male and female flower resolution, female pollination time, bagging materials and bagging time and other characteristics. Through the experimental study on the main characteristics of Jatropha curcas in the dry hot area of Jinsha River and hybrid breeding technology, it is beneficial to improve the breeding effect, accelerate the breeding process and improve the predictability of breeding work.
