Abstract: A population of 48 individualswas developed from cross‘91-42-51’ בRuiguang 2’, and was used to find molecular markers linked to characters as peach or nectarine, yellow or white flesh, male sterility or male fertility by bulked segregant analysis (BSA). The results showed that SSR marker UDP96-018(300 bp) was found linked to peach gene with a distance of 4.5 cM, and UDP98-407 (680 bp ) linked to white flesh gene with a distance of 2.2 cM. Marker NNJ-I ( 600 bp ) and NNJ-I ( 900 bp ) amplified by primers which were designed according to male sterility sequence of Arabidopsis thaliana were tightly linked to male sterility gene with a distance of 0 cM. Markers linked to these characters obtained in this study would provide effective tools for marker assisted selection in peach breeding.
