自1984年起,水稻细菌性条斑病(简称水稻细条病)在我省稻区迅速扩展蔓延,发生面积大,为害严重,成为我省晚稻主要病害之一.推广抗病良种是防治水稻细条病的经济有效措施;而水稻细条病菌系研究又是抗原亲本筛选、抗病品种选育和合理布局的重要基础工作。为此,我们开展了这项研究。材料和方法1.鉴别品种1985~1986年,对400多个水稻品种进行抗性测定,从中筛选出具有鉴别能力的水稻品种V_(64)、010、龙广4号作为水稻细条病菌致病力强弱的鉴别品种。
Since 1984, rice bacterial leaf streak (referred to as rice sliver) spread rapidly in the rice area of our province, the occurrence of large area, serious damage, as one of the major diseases in late rice in our province to promote disease-resistant varieties is the prevention and treatment of rice sliver The economic and effective measures of disease; and the research of rice stripe fungi is the screening of antigenic parents, breeding of disease-resistant varieties and an important basis for the rational layout. To this end, we conducted this study. MATERIALS AND METHODS 1. Identification of cultivars From 1985 to 1986, resistance to more than 400 rice cultivars was determined, and the rice varieties V_ (64), 010 and LongGuang 4 with discriminating power were screened for their pathogenicity Strength of the identification of varieties.
