  粒长(grain length,GL)、粒宽(grain width,GW)和长宽比(length-width ratio,LWR)是衡量稻米外观品质的重要指标,也是影响水稻产量的重要因素之一。弄清粒形性状的遗传基础对有效改良稻米外观品质具有重要意义。本研究所用群体为3套籼籼交重组自交系(RIL)群体,分别为协青早B/密阳46 (XM)、珍汕97B/密阳46 (ZM)和特青/IRBB品系(TI),其中,TI群体抽穗期变异很小,而另2套群体抽穗期变异较大。

RFT1和Ghd7是水稻在长日照条件下控制抽穗期的关键基因,其功能标记的开发将有助于2个基因在水稻分子育种中的应用。我们首先对RFT1的珍汕97 (ZS)和密留46(MY)等位基因进行了测序。序列比较表明,和MY等位基因相比,ZS等位基因在第1外显子上有17个单核苷酸多态(SNP)和1个22bp的插入,在第4外显子上有9个SNP,最终预测蛋白序列存在6个氨基酸置换。根据22 bp的插入/缺失变异,
