Abstract:

Lychee was originated in China. To develop, innovate and utilize the ancient tree resources for lychee breeding is an important task. Through an investigation of the ancient tree resources of Litchi chinensis var. fulvosus, the situation of the resources was systematically grasped, the specific resources were collected and preserved, and a basis for the follow-up lychee breeding research was provided. In addition, the research progress of the investigation on Chinese lychee ancient tree resources, the selection and breeding of germplasm resources and the functional components of L. chinensis var. fulvosus were summarized. The distribution of L. chinensis var. fulvosus resources in Yunnan with the longitude from 101.70° to 103.88° E, the latitude from 22.57° to 25.03° N and the height from 93 m to 1441 m, the growth condition, ripening period, leaf and fruit characters and quality were analyzed. Finally, the problem of the near-death of the ancient L. chinensis var. fulvosus tree resources and suggestions on protection were pointed out.
