Abstract:

The genetic diversity of oriental melon resources was analyzed with RAPD. 11 RAPD random primers produced 78 polymorphic bands, averaged 5.3 bands each primer pair. The average percentage of polymorphic bands was 74.4%. Genetic distance was calculated by the NTSYS-pc software. A dendrogram was constructed by using UPGMA based on genetic distance matrix. 41 accessions were clustered into three groups and eight subgroups based on the RAPD data by the method of clustering analysis, and four groups and twelve subgroups by the method of principal coordinates analysis. The results from these two methods were similar, but the result from the principal coordinate analysis was more informative.
