Prolonged storage of rice tends to cause a lot of losses due to deterioration in seed vigor and grain quality. More and more attention is paid to genetic improvement of rice storability through carrying out genetic research on storability. In this study, an advanced backcross population was developed with Xiushui 134 as the background parent and Yangdao 6 as the donor parent. The one-way analysis of variance based on phenotype-molecular genotype was applied to map the QTLs for storability. A total of 16 QTLs associated with storability were detected at threshold value of -log10（P）>2. Among them, three major QTL were detected on the locus of RM5455 （the relative effect is -12.93%）, RM1132 （the relative effect is -13.76%） and RM248 （the relative effect of -14.66%）.
