中国桉树育种研究进展及宏观策略

桉树（Eucalyptus）是我国南方重要的造林树种,具有生长快、材质好、用途广等优点,发展桉树对增加森林资源、维护木材安全具有重要意义。我国现有桉树人工林360多万hm2,开展桉树育种研究和制定育种策略是一项基础性的工作,对于提高桉树人工林的产量和质量,促进其可持续发展,具有战略指导意义。文中从我国桉树种质资源保存、选择育种、杂交育种到高世代育种等方面对桉树育种进行了全面阐述,并提出一套适合中国国情的桉树育种宏观策略。

Research Progress on Eucalyptus Breeding and Its Strategy in China

Eucalyptus is one of the most important plantation tree species in South China,with the advantages of fast growth,good wood and wide usages.It plays an important role in increasing forest resources and safeguarding wood security.There are now more than 3.6 million hm² of Eucalyptus plantation in China.Conducting Eucalyptus breeding research and establishing breeding strategy is a basic work,which is of strategic significance for improving the growth and quality of Eucalyptus plantation as well as promoting its sustainable development.The paper reviewed Eucalyptus breeding in terms of germplasm conversation,selective breeding and hybridization and came up with a set of marco-strategies of Eucalyptus breeding suiting the national condition of China.
