A recombinant inbred line (RIL) population and two chromosome segment substitution line (CSSL) population derived from the cross of Asominori (japonica) and IR24 (indica) were used to detect QTL controlling seed dormancy.

• 利用由粳稻品种Asominori与籼稻品种IR2 4的杂交组合衍生的重组自交F1 0 家系 (RecombinantInbredLines,RIL)群体及其衍生的染色体片段置换系 (ChromosomeSegmentSubstitutionLines,CSSL)群体 ,进行了种子休眠性QTL的检测和遗传效应分析。
