我县杂交中稻易遭受白叶枯病危害,杂交晚稻易遭受白叶枯病及褐飞虱危害,严重威胁着水稻稳产高产,而选育抗病抗虫品种则是最为经济、安全、有效的防治措施。为了加速选育优势强、熟期早、适应我县栽培、抗病抗虫的优良组合,1977年我们进行了杂交水稻品种对白叶枯病及褐飞虱的抗性鉴定试验。 Rice hybrid rice susceptible to bacterial blight in our county, late blight susceptible to bacterial blight and brown planthopper in late hybrid rice, a serious threat to the rice yield and stability, and breeding of resistant varieties is the most economical, safe and effective control measures . In order to speed up the breeding of strong advantages, early maturity, adapted to the county’s cultivation, disease resistance and insect resistance of the excellent combination, in 1977 we conducted hybrid rice varieties of resistance to bacterial blight and brown planthopper resistance test.
