摘要： 稻属有22个种，包括20个野生稻种和2个栽培稻种，现已命名AA、 BB、 CC、 BBCC、 CCDD、 EE、 FF、 GG和HHJJ 9个基因组。野生稻是一个重要的有利基因库，包含对各种生物胁迫的抗性和非生物胁迫的耐性基因。就野生稻的有利性状、野生稻有利基因转移研究进展作了概述，并对野生稻有利基因分子标记定位研究，野生稻有利基因转移的遗传机制以及野生稻有利基因利用前景进行了讨论。

Abstract: There are two cultivated and twenty wild species of genus Oryza. These wild species of Oryza with 2n=24 or 48 chromosomes representing AA, BB, CC, BBCC, CCDD, EE, FF, GG and HHJJ genomes are an important reservoir of useful genes. Resistance to biotic and abiotic stresses as well as useful traits of wild species are described, and the recent advances on utilization of wild species for transferring elite gene into cultivated rice from wild species are summarized. The molecular mapping of alien genes introgressed from wild species into rice and mechanism of alien introgression as well as the prospects of utilization of wild species are also discussed.

Key words: wild rice, germplasm, alien introgression, molecular mapping
