With rich Pyrus. germplasm resources in China, the molecular genetic linkage map construction andagronomic traits or gene lacation have an important significance on the molecular marker assisted breedingof pea. In this study, the ‘Shinseiki’originated from western Japan was used as female parent, the‘Chonghuadali’ originated from Sichuan province in China was used as the male parent, and210strains ofF1hybrid of them were used as mapping group. JoinMap4.0was ued to construct a pear genetic linkagemap based o...
