安仁基点水稻新品种抗白叶枯病研究进展

Research Progress on Bacterial Blight Resistance of New Rice Cultivars at Anren Experimental Station

湖南省农科院水稻研究所安仁基点通过对水稻白叶枯病的多年研究,找到了水稻白叶枯病的发生规律,提出了以选用抗病、优质、高产品种为中心,以栽培管理为基础,药剂防治为辅的防治措施;鉴定了白叶枯病材料5万多份,筛选出高抗材料100多份,抗病材料500多份;在此基础上,选育出了一批多抗性品种在生产上应用,产生了很好的社会、经济及生态效益。认为筛选抗源、选育抗多种病、虫的抗性品种仍是今后育种的重要目标。

Many years of research on rice bacteria blight by Rice Research Institute,Hunan Academy of Agricultural Science at Anren experimental station was conducted,and the occurrence regularity of rice bacterial blight was found,and the prevention measures were put forward,which included breeding multi-resistance varieties,medicament applied and cultivation management.In recent years,more then 50 000 materials were identified,and more the 500 resistance varieties and more than 100 high resistance varieties were screened.On this basis, a series of multi-resistance rice varieties were breeded,which produced very good economic,social and ecological benefits.The important targets of paddy rice breeding were screening of resistance resources and breeding of multi-resistance rice varieties to disease and pest.
