【摘要】 １９８６～１９９０年，采用病区病圃剪叶接种法，对杂交稻三系资源及组合３０９８份进行了鉴定。筛选出一批抗性较好的资源及组合。其抗性强弱依次表现为恢复系＞杂交稻组合＞保持系＞不育系。对杂交稻抗由叶枯病育种的亲本选择提出了看法。更多还原

【Abstract】 In 1986-1990 the leaf inoculation method was used in a diseased area or nursery to identify 3098 three line materials and rice hybrids. and a series of materials and hybrids with stronger resistance to leaf blight were selected,Their resistance w4s in order of restorer line > rice hybrids > maintainer line>sterile line.How to choose parents for leaf blight resistant hybrid rice breeding is also discussed in the paper.更多还原
