摘 要:野生稻广泛分布于亚洲、非洲、拉丁美洲和澳洲的77个国家,目前公认有21个野生种,我国有3个野生种。野生稻具有大量栽培稻目前缺乏的的优良特性(基因),成为栽培稻遗传改良的丰富基因源和重要的物质基础。我国是水稻生产大国,但白叶枯病、稻瘟病、纹枯病等各种病害一直严重影响着水稻生产。从我国野生稻挖掘和利用抗病材料(基因),是培育抗病品种的重要途径。本文综述了我国野生稻资源的抗病性鉴定与利用研究进展,提出了存在的问题和加强研究的建议。Wild rice distributes widely in 77 countries of the Asia,Africa,Latin America and Australia. It is generally accepted that there are 21 wild rice species in the world,but only 3 in China. Wild rice has a number of elite characteristics( genes) which have been not found in cultivars so far. Wild rice is considered to be a rich gene pool and important basic material for rice genetic improvement. China is a large rice producer,but some diseases such as bacterial blight,blast,sheath blight,have seriously affected rice production. It is an important way for breeding resistant varieties to discover and utilize disease-resistance genes from Chinese wild rice. This paper reviewed the research progress on identifying and utilizing disease-resistance resources in Chinese wild rice. In addition,the present problems and some suggestions on further research were also discussed.
