Abstract:

SSR technique was used to develop fingerprinting key and study the genetic diversity on sweet cherry. Eighteen pairs of primers cloned from cherry, peach and apricot amplified a total of 83 alleles among the 19 cultivars of sweet cherry ( Prunus avium ) and 2 cultivars of ground cherry ( P. fruticosa). The number of alleles amplified per primer pair ranged from 2 to 8, with a mean of 416. The polymorphic information content values ( PIC) ranged from 0.38 to 0.80, with a mean of 0.64. Seven sweet cherry cultivars showed unique bands or banding patterns. A fingerp rinting key developed by 4 pairs of p rimers: UDP98-414, UDP98-406, UDP96-001 and PMS40 could discriminate 18 sweet cherry cultivars. UPGMA cluster analysis of genetic distance separated the 19 cultivars of sweet cherry into two group s. The phylogeny of sweet cherry cultivars revealed the closed relationships among cultivars tested.

Key words: sweet cherry, SSR, genetic diversity, cultivar identification, fingerprinting key
