【Abstract】 Germplasm resources are the basis of fruit tree breeding and germplasm innovation. In order to better protect, develop and utilize Litchi germplasm resources, the current collection, protection and utilization of litchi germplasm resources were analyzed and summarized in Dongguan, and some suggestions for the development of Litchi germplasm resources were put forward. In the face of some excellent litchi germplasm resources gradually reduce, establishing dongguan characteristics of litchi germplasm resources conservation nursery as soon as possible, the diversity of the use of special funds to maintain personnel resources, systematic for investigation, dongguan litchi germplasm collection excellent germplasm resources, grafting in resource conservation nursery, the development of dongguan litchi industry provides powerful resources support, Provide parents for cross breeding and seed selection. At the same time, comprehensive phenotypic and genotypic identification of germplasm resources was carried out, and excellent resources were screened to lay a solid foundation for new variety selection and production and application, so as to accelerate the germplasm innovation and new variety selection process of litchi.更多还原
