摘要
应用水稻稻瘟病抗性基因Pi-1紧密连锁的3个微卫星标记RM144、RM224和MRG4766对黑龙江省49主栽水稻品种(系)进行抗瘟基因Pi-1检测分析。结果表明,用3个与抗瘟基因Pi-1紧密连锁的SSR标记同时对抗瘟基因Pi-1有检测是非常有效的途径,检测到富士光等14个水稻品种(系)含有Pi-1抗瘟基因,明确了该基因在黑龙江省水稻品种(系)中的分布情况,为分子育种、合理搭配种植品种等提供了理论依据。
The microsatellite （SSR） markers RM144,RM224 and MRG4766,which are tightly linked to the blast resistance gene Pi-1 in rice, provides means to identify the blast resistance gene Pi-1 in 49 rice varieties commercially grown in Heilongjiang province. The results showed the identified means was very effective; cultivars Fushiguang et al. were identified having the Pi-1 gene; knowing distribution of the Pi-1 gene in rice varieties; provided theoretical evidence for molecular breeding,reasonable plant and against rice blast.
