Abstract

Abstract: Genetic linkage maps for two apricot cultivars have been constructed using simple sequence repeat（SSR）and sequence-related amplified polymorphism（SRAP）markers in 94 F1 individuals from the cross Chuanzhihong × Golden-sun. A total of 37 SSR and 32 SRAP markers were placed into 14 linkage groups on the Chuanzhihong map，defining 1 086.6 cM of the total map-length，and the average length of group was 77.6 cM. The average distance between adjacent markers was 19.7 cM. The male parent map of Golden-sun consisted of 26 SSR and 14 SRAP markers could be assigned to 7 linkage groups，defining 756.7 cM of the total map-distance. The average distance of group was 108.1 cM，with an average interval of 22.9 cM between adjacent markers. Segregation type of heterozygous loci in F1 was discussed in constructing map of apricot.

Key words: apricot, heterozygous loci, molecular markers, segregation type, linkage map
