淹涝胁迫对水稻生产造成了严重影响, 发掘可应用于耐淹涝辅助选择的分子标记(MAS), 将有助于水稻耐淹涝性状的遗传改良.应用耐淹涝材料FR13A和淹涝敏感材料IR39595-503-2-1-2为亲本做正反交获得F_1和F_2代群体.对正反交的F_1群体的耐淹涝性状进行遗传分析, 发现正反交的F1代群体在耐淹涝性状上没有显著差异, 说明耐淹涝性状是核基因控制.从两次淹涝处理中F_2代群体的分离情况来看, 来源于FR13A的耐淹特性表现出数量-质量性状遗传的特点.当淹涝胁迫压力比较轻时表现为数量性状遗传, 具有微效多基因的作用.当淹涝胁迫压力增大时, 表现为主效基因控制的质量性状.在SSR分析中, 187对SSR引物中有73对...

Submergence stress has severe harm to rice (Oryza sativa L.) production. It is important to identify molecular markers associated with tolerance to submergence for marker-assisted selection (MAS). F1 and F2 populations ware obtained from reciprocal crosses between submergence tolerant parent FR13A and submergence sensitive parent IR39595-503-2-1-2. No difference in reciprocal crosses in F1 population was detected for tolerance to submergence. This indicates that the submergence character is controlled by nucleic factor(s). Tolerance to submergence derived from FR13A appeared to be a quantitati...
