果树种质资源保存研究进展

Progress Research on Conservation of Fruit Germplasm Resources

  • 摘要: 保存多样性的果树种质资源对育种、生产十分重要。我国作为世界果树起源中心之一,果树资源丰富,产业发展迅速,利用现有条件,加强果树种质资源的保存力度,为后期育种打好基础。该研究主要阐述了种质资源作为果树育种的基础和原始材料,可以直接作为栽培品种用于生产或在育种过程中作为亲本使用。同时具体介绍了目前果树种质资源保存的3种主要方式(原生境保存、迁地保存和离体保存),进而分析了我国种质资源保存过程中存在的种质资源流失严重、缺乏系统的保存体系、种质资源库建设不完善等问题,并且提出了相关发展方向和建议。

     

    Abstract: It′s very important to preserve the diversity of fruit germplasm resources for breeding and production.As one of the origin centers of fruit trees in the world, China has abundant fruit resources and rapid development of the industry.The existing conditions should be used to strengthen the conservation of fruit germplasm resources and lay a good foundation for later breeding.In this study, germplasm resources were mainly used as the basis and raw materials of fruit tree breeding, which could be directly used in the production of cultivars or used as parents in the breeding process.At the same time, three main conservation methods of fruit germplasm resources were introduced, in situ conservation, ex situ conservation and in vitro conservation.The problems of serious loss of germplasm resources, lack of systematic preservation system and imperfect construction of germplasm resource bank were analyzed, and the related development direction and suggestions were put forward.
