To study the genetic diversity of the melon collection
at the National Plant Genetic of Iran, 35 genotypes were planted at Bu
Ali Sina University Hamedan in 2004 and were evaluated with 15 micro satellite
SSR markers. Micro satellite markers in the upper levels showed polymorphisms
and 87% of them are polymorphic and 63 alleles have been identified. The
number of effective alleles in the polymorphic loci varied from 1.25-8.19
and the mean is 2.80. The percentage of genetic loci having polymorphism
is 87.67%. Cluster analysis of genotypes was divided into 5 groups wherein
genotype of foreign origin has smooth skin while different groups of Iran
genotype are netted. Genetic distance between Iranian and foreign is 0.98.
Results obtained from this study showed the significant difference between
Iranian genotypes with other genotypes. These genotypes have high diversity
which could be used in breeding programs.
