【摘要】 我国开展刺槐遗传育种研究起始于20世纪70年代初,育种历程大致划分为3个阶段。第1阶段是刺槐速生良种选育阶段,时间是从20世纪70年代初至80年代末期;第2阶段是刺槐用材林无性系定向选育阶段,时间是从20世纪80年代末至90年代末期;第3阶段是刺槐观赏、饲用等专用品种引进和选育阶段,时间是从20世纪90年代末至今。作者概括了每个阶段开展刺槐育种研究的单位及取得的成就,列出了每个阶段选育的刺槐良种名录,全国10余个省市区的林业科研、教学单位共选育了100余个优良无性系、14个优良家系和3个优良次生种源。总结了我国刺槐良种推广应用中存在的问题,提出了今后刺槐育种发展策略和创新研究方向。更多还原

【Abstract】 The research on genetics breeding of Robinia pseudoacacia L.which started in the early 1970s has been more than 30 years in China,and its course was divided into three stages,of which the first one was selection and breeding of fast-growing superior varieties that from the early 1970s to the late 1980s.Then the second stage was clones breeding on timber stand,which from the late 1980s to the late1990s.Then the third stage was improved varieties introduced and breeding for ornamental,feed and so on,which from the late 1990s to now.The paper summarized the unites of breeding study and their achievements during every stage,gave lists of improved clones,improved families and improved secondary provenances of Robinia pseudoacacia L.in each stage,and concluded current situation and existing problems of its popularization and application in China.At last,future breeding development tactics and innovative research direction of Robinia pseudoacacia L.were put forward.更多还原
