DETERMINATION OF THE GENETIC DIVERSITY AND THE POPULATION STRUCTURE OF LOCAL MELONS COLLECTED FROM LAKES REGION IN TURKEY

In this study 105 landraces melons (Cucumis melo L.), mostly winter melons (inodorous) at S3 level, were studied. Genetic diversity analysis was performed with 11 ISSR markers. According to the results of the analysis, some genotypes formed two different populations as red and green. In addition, other genotypes were determined to consist of a mixture of these two populations. As a result of the data obtained, the total number of alleles was 7.64. Polymorphism was determined as 80.4% (polymorphic allele number 6.09). In the cluster analysis, two different groups were formed. There were 193 and 195 genotypes in the first group and other genotypes in the second group. In the dendrogram, the 193 and 195 genotypes are the furthest. The 21 and 22 genotypes were found to be closest. Although genotypes were taken from the same places, it was determined that they are different from each other. Molecular genetic data are thought to make an important contribution to future breeding studies.
