Thirty-three coffee SSR primers from enriched genomic library with (GT)15 and (AGG)10 repeats were analyzedin 24 coffee tree accessions. Twenty-two primers were polymorphic among accessions; the number of alleles ranged from 2 to13, with the mean number of 5.1 alleles per primer. PIC values ranged from 0.08 to 0.79. The highest mean PIC values werefound for C. canephora (0.46), and the lowest values for C. arabica (0.22) and triploids (0.22) accessions. The polymorphicSSR markers used in this study were useful for genetic fingerprinting in the coffee tree, especially in the C. canephora and theleaf rust resistant arabica cultivars.
