Quantitative trait loci(QTL)for heading date were detected in rice by using an F2population derived from the cross Shennong 265/Lijiangxintuanheigu. Totally,7 QT Ls for heading date were detected on chromosome 2,3,6 and 7,respectively. Comparison among different studies revealed that most QT Lsfor heading date were easy to be redetected in different materials and environments.And a new QT L locus for heading date was detected in this study. These results prO2 vide the basic data for selecting heading date of the Japonica rice breeding.
