摘要:
利用以粳稻日本晴为受体、籼稻9311为供体的经全基因组重测序的染色体片段代换系为材料,以水稻耐热指数[(常温结实率-高温结实率)/常温结实率]为评价指标,通过比较江苏扬州2013年大田极端高温和2012年常温条件下水稻耐热性的差异来定位水稻耐热性QTL (数量性状基因座位)。共检测到3个耐热性QTL,分别位于第2、第4和第12号染色体上,LOD(logarithm of odds)值分别为2.56、4.02和2.79,贡献率分别为4.95%、7.99%和544%。其中qHT12.1表现为正向效应,而qHT2.1qHT4.1表现为负效应。相关研究为后续耐热QTL的精细定位、克隆和高温钝感型优异品种的培育提供了依据。
