摘　　要：野生稻是现代栽培稻的祖先,几万年前古人类就开始将野生稻逐步驯化成现代栽培稻。但在野生稻驯化成栽培稻过程中,约有1/3的等位基因和1/2的基因型丢失了,其中包括抗病、虫、杂草、抗逆境基因和高产优质等大量特异基因。文章综述了近年来在野生稻抗病性(稻瘟病、白叶枯病、细菌性条斑病),抗虫性(稻飞虱、三化螟、稻纵卷叶螟),抗逆境(耐冷性、耐旱性、耐低磷)以及野生稻种质资源在水稻育种上利用的研究进展。The wild rice is the ancestor of modern cultivated rice.Tens of thousands years ago,ancient human domesticated wild rice into cultivated rice.However,in the process of domestication,about 1/3 alleles and 1/2 genotypes from wild rice has been lost including disease-resistance,insect-resistance,weed-resistance,stressresistance and high yield and quality genes.The genes of disease-resistance（rice blast,bacterial blight,bacterial leaf streak）,insect-resistance（rice hopper,yellow rice borer,Cnaphalocrocis medinalis Guenee）,stress-resistance（cold resistance,drought resistance,low phosphorous resistance） from wild rice and the utilization of wild rice on rice breeding were summaried in recent years in the paper.
