龙眼种质资源亲缘关系的研究进展

Advances in the Genetic Relationship of Longan Germplasm Resources

摘要:

龙眼(Dimocarpus longana Lour.)种质资源是龙眼育种研究的基础。种质资源的研究将为探讨龙眼起源、进化、分类、育种和资源保护与利用提供科学依据。从形态学、孢粉学、同工酶和分子生物学等方面综述了龙眼种质资源亲缘关系的研究进展，探讨了龙眼亲缘关系的研究现状、前景及尚待解决的问题，并分析了今后开展龙眼种质资源亲缘关系研究的方向与重点。

Abstract:

Longan germplasm resources are very important for the breeding study. The genetic relationships of germplasm resources are the scientific basis for longan’s origin, evolution, classification, breeding and application. The research advances in genetic relationships of longan germplasm are reviewed in the following aspects:morphology, palynology, biochemistry and genetics. The prospects of longan germplasm resources are also discussed.
