| 摘 要： | 我国引种桉树的历史已经超过120 a,收集和保存了大量的桉树种质资源,这是桉树育种工作的基础。育种目标是育种工作者首先要明确的问题,是指培育的品种应具备哪些主要性状,育种目标制定恰当与否是决定育种工作成败的关键。本文回顾了我国桉树种质资源的收集、保存及利用现状,对桉树育种目标体系的建立进行了总结和讨论,旨在为我国桉树育种研究提供理论指导和技术参考。

| Abstract: | Eucalyptus species were introduced into China more than 120 years ago. Since then, a huge range of genetic resources d these species have been established in southern China. These provide an excellent base for genetic improvement of Euca/yptus species in this country. Selection objectives used to date in south- ern China mainly include growth rate and othea- easily measured economic traits. F_~cient selection objectives are crucial to success and genetic progress from Euca/yptus breeding. Collection, conservation and selection of Eucalyptus genetic resorces were reviewed in this report and the development of selection and breeding objectives for Euoalyptus species were summarized and discussed. The discussion provides theoretical rderences and technical guidance for Eucalyptus breeders in China. |
