title: Genetic  diversity among melon accessions (Cucumis melo) from Turkey based on SSR  markers.
abstract: Melon (Cucumis melo) is an important vegetable  crop in Turkey, where it is grown in many regions; the most widely planted  lines are local winter types belonging to the var. inodorous. We examined  81 melon genotypes collected from different provinces of Turkey, compared with  15 reference melon genotypes obtained from INRA/France, to determine genetic  diversity among Turkish melons. Twenty polymorphic primers were used to  generate the SSR markers. PCR amplification was performed and electrophoresis  was conducted. SSR data were used to generate a binary matrix. For cluster  analysis, UPGMA was employed to construct a clustering dendrogram based on the  genetic distance matrix. The cophenetic correlation was compared with the  similarity matrix using the Mantel matrix correspondence test to evaluate the  representativeness of the dendrogram. A total of 123 alleles were amplified  using the 20 SSR primer sets. The number of alleles detected by a single primer  set ranged from 2 to 12, with an average of 6.15. The similarity ranged from  0.22 to 1.00 in the dendrogram developed from microsatellite analysis. Based on  this molecular data, we concluded that genetic diversity among these Turkish  accessions is relatively high.
