| 摘 要： | 选用稻瘟病抗源外选35及其衍生系统持久抗性品种三黄占2号、三芦占7号、梅三五2号及其衍生品种矮三芦占、七黄占2号、七袋占分别与野败型不育系博A、优ⅠA、Ⅱ优A、红莲型不育系广A配制共28个组合。以IR36为抗性对照，广陆矮4号为感病对照，对杂交组合及其不育系（保持系）和抗性品种进行了人工接种稻瘟病菌抗谱测定，数量抗性测定和不同病区田间异地同步抗性鉴定。抗性分析和比较结果表明：具持久抗性品种三黄占2号、三芦占7号配制的杂交组合表现了与持久抗性品种相同的表型特征，即表现较高的质量抗性和数量抗性, 较好的田间抗性。初步认为：三黄占2号和三芦占7号的持久抗性能导入三系杂交稻组合中。

| Abstract: | Hybrid rice combinations made by
seven blast resistant cultivars including three durably resistant cultivars and four popular
sterile lines were studied.The qualitative resistances,quantitative resistances and field
resistances in different blast conducive areas were evaluated and compared with the resistant
check IR36 and susceptible check Guanglu'ai 4 respectively.Results indicated that the
combinations with durably resistant donor showed the same durably resistant characteristics
as correspondently durably resistant cultivars. These results suggested that durable resistance
to rice blast could be incorporated into hybrid rice. |
