Rice variety 9194 black streaked dwarf restricting locus and molecular marking method thereof

The invention relates to a rice variety 9194 black streaked dwarf restricting locus and a molecular marking method thereof. Four rice variety 9194 black streaked dwarf restricting locus are obtained by carrying out genetic linkage analysis on the black streaked dwarf resistance level of the genotype of an F2 single plant obtained from hybridization of the black streaked dwarf restricting rice variety 9194 and susceptible variety suyunuo and the corresponding F2:3 family, wherein qRBSDV3 is positioned between the markers RM282 and RM14898, qRBSDV6 is positioned between the markers RM20069 and RM30, qRBSDV9 is positioned between the markers RM3912 and RM257, and qRBSDV11 is positioned between the markers RM26062 and RM536. The molecular markers of the black streaked dwarf restricting gene are used for detecting whether the resistant variety 9194 and the derived varieties contain the black streaked dwarf restricting locus, so that the resistance level of the black streaked dwarf can be predicated, and the selecting efficiency of the black streaked dwarf restricting rice is greatly improved.
