Abstract:Based on the SSR molecular marker and Jionmap 3.0 analysis a genetic linkage map of pear was constructed with F1 populations from a cross of ‘Housui’ and ‘Dangshansuli’.The map consisted of 18 linkage groups and located 104 SSR markers covered 831.8 cM of pear genomic with an average distance of 8.0 cM per markers.According to the 25 commom SSRs marked on this pear map and the apple ‘Fiesta’ map,the homologous linkage groups were well connected to each other and it showed high level of co linearity between the two maps.SSR markers on the map can be taken as anchor points to be merged with other maps.
