    Abstract:

    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 in identifying and utilizing disease-resistance resources in Chinese wild rice. In addition, the present problems and some suggestions on further research were also discussed.
