摘要: 通过回交及自交,并结合分子标记辅助选择,将广谱抗源H4的一个主效抗稻瘟病基因 Pi46 导入到优良恢复系航恢173中,并在BC2F4群体中选育到一个株叶形态较好的株系,暂命名为航恢1173。分析结果表明,航恢1173比航恢173的抗谱得以明显拓宽,并无显著的农艺性状差异,且所配杂交组合的抗性也得到显著的提高。

关键词: 稻瘟病, 恢复系, 分子标记辅助选择

Abstract: Cultivar Hanghui 173 is the restorer line,a parent for a number of hybrids in our research group.However,cultivar Hanghui 173 is highly susceptible to rice blast.In this study,a rice blast resistance gene Pi46 was introgressed to improve the blast resistance and amylose content of Hanghui 173 and its derived hybrids,by marker-assisted selection (MAS).Our results showed that,the improved Hanghui 1173 conferred a broad spectrum resistance and showed stable panicle blast resistance for five at natural blast nursery.The result of examining agronomic traits showed that the improved Hanghui 1173 and its hybrids were similar to controls.

Key words: Rice blast, Restorer, Marker-assisted selection
