Abstract: Seed dormancy is one of the most important traits related to rice quality and seeds application, because it is associated with pre-harvest sprouting, resulting in a downgrading of quality and severe limitations in end-use application. Recent development of DNA markers and linkage maps of rice has made possible mapping of individual genes associated with complex seed dormancy traits, analyzing the genetics effects of individual genes and genotype-by-environment interactions. Up to now, numerous QTLs associated with seed dormancy in rice have been identified and mapped in the molecular genetic map by different populations. In this review, the genetics bases of seed dormancy in rice are analyzed, the quantitative trait loci (QTL) controlling seed dormancy reported up to now are compared, the expression and stability of QTLs controlling seed dormancy are studied, and the difficulties and new pathways in further research of seed dormancy are discussed.
