Abstract Disease is a serious threat for the production and quality of rice. Research progress of the occurrence regularity, damage degree and prevention techniques of main rice diseases in China were reviewed, such as rice blast, bacterial blight, sheath blight and false smut disease. Meanwhile we looked forward to the development of disease prevention in rice. It was pointed out that the control of rice disease mainly lied in the rapid breeding of disease resistant varieties. We should strengthen gene technology and molecular marker assisted breeding in the future breeding process. Thereby, we would accelerate the polymerization breeding of many disease resistant genes in rice.

水稻是我国主要的粮食作物之一,每年稻谷产量1.87亿t,为世界第一[1-2]。随着人口的急剧增加、耕地面积的逐渐缩小,对水稻的需求量逐渐增加,加上人们生活水平和生活质量的提高,对水稻品质也有了更高的要求。病害不仅是限制水稻产量增加的一个主要因素,它还严重影响水稻品质[2]。与其他作物一样,水稻在种植生长发育期间,不可避免地会受到一系列病原菌的侵害,其中水稻稻瘟病、白叶枯病和纹枯病是分布最广泛、危害最严重的3种病害,严...
