BSA analysis for SSR markers
PF, PS, BF, BS, and F1 represent 93-11, Pei′ai64S, fertile bulk, sterile bulk, and F1 hybrid of a cross of Pei′ai64S/93-11, respectively. The PCR products were separated in non-denatured 0.06 g/ml polyacrylamide gel electrophoresis, and visualized by quick silver-staining. The bands were amplified by two SSR primers (RM21242 and RM432)
