褐飞虱(Nilaparvata lugens St??l)是水稻的主要害虫之一,培育和应用抗虫品种是防治褐飞虱极为经济有效的措施.70年代以来通过抗源种质鉴定和杂交组合,相继育成许多抗褐飞虱水稻品种,对减少田间用药,防止污染,降低生产成本和控制褐飞虱为害起到了重要作用.本项研究旨对当前推广种植的IR26、IR36和汕优6号等抗褐飞虱品种的苗期和分蘖期的抗性进行测定,供育种和生产部门参考.
Nilaparvata lugens St? L is one of the major pests in rice, and it is extremely economical and effective to control and develop BPH by using the varieties of insect-resistant cultivars. Since 1970s, many resistance to BPH Rice varieties played an important role in reducing field drug use, preventing pollution, reducing production cost and controlling the brown planthopper infestation.This study aimed to investigate the effects of the current poplar planting varieties IR26, IR36 and Shanyou 6 on seedling stage and tillering stage The resistance was measured for breeding and production sector reference.
