摘　　要：本文论述我国柚木基因资源分布的特点、遗传变异和改良的策略及途径。 我国有悠久的柚木栽培历史,基因资源分布于南方7省46个县(市),其生长情况与原产地相当。从1973年起,我们对柚木进行系统的改良,已取得较好的成果,种源选择和无性系测定的两项效益均超过原改良方案的估计。在此基础上制订了我国柚木长期系统的改良方案,采取与我国柚木基因资源分布特点、具体情况相适应的策略以及改良途径。This paper describes the distribution characteristics of teak germplasm in China and their genetic variation. A strategy and the way for teak improvement are also put forward in this paper.Teak has been cultivated in China for more than 100 years. The genetic resources distributed in 46 counties/cities of 7 southern provinces. The growth appearance is very close to that in the natural distribution areas of India, Burma and other countries. Satisfactory results on teak improvement have been obtained since we started systematic teak breeding and improvement programme in China. The benefits from both the provenance selection and the clones of superior provenances overpassed the estimation of the original improvement plan. A strategy and the way for teak improvement were worked out according to the past improvement experiences, the characteristics of China's teak germplasmic distribution, and other related situations.
