PCR amplification of markers linked to BB resistance genes Xa21, xa13, xa5, Xa4 using primers pTA248, Xa-13 prom, RM122, MP-Nbp-131 and submergence tolerance QTL, Sub1 using primers Sub1-A203, Sub1-BC2 Sub1-C173 and RM8300 in BC2F1 derivatives. Lanes on the top of the gel indicate the BC2F1 plant designation; L-Molecular weight marker (50 bp plus ladder).
