Abstract: A linkage map of peach was const ructed with AFL P , SSR and RAPD markers in 109 F2population derived f rom the cross of ‘Okubo’and‘Xingjin’nectarine. The selected primers including 36 AFLP , 3SSR and 2RAPD with rich polymorphism and steady bands were tested in progeny. 136 markers
were scored , of which 27 markers were skewed segregation by X2 test . Mapmaker were used to assigned the expected segregation markers to 11 linkage groups , the number of loci mapped in the 11 linkage group
was 3 - 21 and there was 8.73 (average value) loci per group. Whole length of linkage map was 1061.8 cM , The average length of 11 groups was 96.5 cM , and average interval between markers was 11.0 cM.
RAPD markers linked to G/ g , Y/ y and AFL P markers linked to D/ d gene were located in group 3 、group
7 and group 9 respectively.
