| Abstract:
Microsatellite and AFLP markers have been utilized to characterize six apricot cultivars and advanced selections. All of the cultivars tested could be clearly identified by SSR and AFLP markers. A total of twenty primer pairs flanking microsatellite loci were used. All the primers revealed polymorphisms among the cultivars tested. The high degree of polymorphisms of microsatellite markers allows a rapid efficient identification of apricot genotypes. A specific PCR marker developed for S-allele genotyping of sweet cherry as used to reveal possible variation among the tested apricots. Three of the apricots showed different S-alleles. The corresponding bands were sequenced and compared to those of sweet cherry. Apparently there is synteny between the genomes of apricot and sweet cherry. | |
