摘要
本文从我国桉属树种遗传改良工作存在问题着手,根据桉属的生物学特性,论述了育种策略、育种计划、杂种利用、种子生产基地、无性系林业等当前亟需解决的几个问题。强调遗传改良工作的成败取决于正确的育种策略和一个完整的育种计划。加强对基因资源的管理并进一步补充完善育种群体是育种工作者的主要工作领域。从整体出发,在不断扩大育种群体、提高遗传品质的同时,为生产提供更多、更好的种和苗。
Beginning with an statement of existing problems in eucalyptus tree improvement in South China, this paper discusses some issues relating breeding strategies, breeding plans, hybrid utilization, seed production bases and clonal forestry in accordance with their biological characteristics. It is also pointed out that the success of genetic improvement program depends on the correct breeding strategies and a complete breeding plan. The major tasks of the tree breeders, therefore, are to enhance the management of genetic resources and to further complete and replenish the breeding population. Starting from the overall interests of the whole society, while expending the breeding population and improving the genetic character, the tree breeders must pay attention to supplying mass plantation with high quality planting stocks.
