After analyzing glutinous rice waxy gene sequence reported by previous studies, two pairs of dominant and codominant STS molecular markers based PCR were designed for distinguishing glutinous rice, according to the distinctions between glutinous rice wx gene and nonglutinous rice Wx gene. Moreover, the whole sequences of the two Wx genes of nonglutinous rice reported by others were also aligned, and another two pairs of dominant STS molecular markers were designed to discriminate Wxa from Wxb based on the special site between the two genotypes. Then, corresponding rice genotypes were identified by the established new markers.
