黑麦属基因资源研究进展

黑麦（Secale L.)是丰富小麦（triticum aestivum L.)遗传变异、选育小麦优良新品种的重要基因资源。迄今黑麦属在系统分类、细胞遗传学、分子遗传学和小麦育种中的利用等方面的研究均已取得了令人瞩目的进展。本文主要从以上四个层次，概述了黑麦属在分类、分布、核型带型分析、黑麦染色质的鉴定、重复序列研究、遗传图谱构建和利用黑麦改良小麦的育种实践等几个方面的最新进展。同时，对当前如何深入开拓和利用黑麦属基因资源进行了讨论。

Advances of Study on the Genetic Resources of Secale

Secale L. is one of the important resources for wheat breeding. Great advances have achieved in rye systematics, cytogenetics, molecular genetics and utilization in wheat breeding. The progresses of the four subjects are briefly summarized in this paper, concretely including its taxonomy, chorology, karyotype, banding pattern, chromatin detection in wheat genetic background, genomic repeat sequences, genetic linkage mapping and some good examples in successfully transferring rye germplasm into wheat cultivars. Currently, with the development of molecular bio technology, further advances would be acquired in the future.
