中文摘要：

利用分子标记可以寻找并且定位目的基因,分子标记辅助育种技术则能够快速、高效地筛选出携带目的基因的优良品种。文章总结了近年来水稻中已被定位的优良性状控制基因及与其连锁的分子标记,其中包括抗病虫害、抗寒、抗旱、不育、育性恢复等194个基因,这些基因中已有14个被克隆测序。在此基础上探讨了这些基因在染色体上的分布趋势。

英文摘要：

Mapping a target gene is useful to isolate the gene or get molecular marker for molecular marker-assisted selection. This paper summarized the recent studies of gene mapping in rice, including 194 genes. These genes are involved in disease resistance, cold tolerance, drought resistance, sterility, and fertility restoration of rice. The molecular markers that link with these genes were also summarized. Among these genes 14 have been cloned and sequenced. According to the results this paper also analyzed genes distribution rule in chromosomes.
