以 Ａｓｏｍｉｎｏｒｉ／ＩＲ２４重组自交系为材料，对控制稻米粗脂肪含量的 ＱＴＬｓ进行了分析，检测到了１个控制粗脂肪含量的ＱＴＬ（Ｆａｉｌ），位于第１０染色体的长臂上，贡献率为１９％，其遗传正效应等位基因来源于粳稻亲本Ａｓｏｍｉｎｏｒｉ，加性效应为０．４１％。
QTLs controlling crude fat content in rice were analyzed using Asominori / IR24 recombinant inbred lines. One QTL (Fail) controlling the crude fat content was detected and located on the long arm of chromosome 10, with a contribution rate of 19 %, And the positive allele of this gene was derived from Asominori, a japonica rice parent, with an additive effect of 0.41%.
