简介：F9recombinant生来的线(RIL)人口，源于在IR28之间的一个十字(OryzasativaL。spp。indica)并且Daguandao(O。sativaL。spp。装饰用的梨树)，被用来构造一张分子的连接地图并且为23d在14°C包括吸收率，萌芽率，萌芽索引，根长度，射击长度和种子活力的特点识别萌芽能力。印射途径的合成间隔被使用为萌芽能力进行基因分析。在寒冷下面的萌芽能力特点的频率分布在RIL强调人口显示出连续分离，建议他们是几基因控制的量的特点。七QTL的一个总数在染色体上被识别4，6和9，为吸收率包括二(qIR-6，qIR-9)，为萌芽率(qGR-4)的，二为萌芽索引(qGI-4-1，qGI-4-2)并且二为根长度(qRL-4-1，qRL-4-2)。没有控制射击长度和种子活力的检测QTL。单个QTL解释的phenotypic变化从9.1%～37.0%，和二主要QTL，qIR-6和qGI-4-2，占了超过30%phenotypic变化。QTL的表情是精神上发展调整并且生长阶段特定。大多数这里观察的QTL为冷忍耐以前报导了的米饭位于类似于QTL的区域，显示这些QTL是可靠的。然而，qRL-4-2以前没被报导。
