Abstract
Iran is a part of the secondary center of origin of melons, and therefore, there is a wealth of genetic variation of these species in this country. In this work, 14 morphological traits were studied in order to select the most discriminating traits. Significant difference among accessions was revealed for almost quantitative traits. KMO coefficient obtained was 0.723 that is explaining of appropriation of this test. The results of the principal component analysis (PCA) for the morphological traits indicated that the first three PCs explained 53.46% of the total variation. Principal component analysis results (PCA) for morphometric data indicated that samples of Semnan and Khorasan showed high degree of variation and were highly different from Sistan and this approved by cluster analysis. Cluster analysis grouped the 36 accessions into three clusters confirming the diversity of the collection that can be useful for selection and source of desired genes.

Escribano and Lázaro [5], morphological study was designed to characterize some of the analyses is the main requirement in the initial fruit and morphological traits of 36 selected assessment of genetic variation for melon accessions from the eastern warm and classification and identification of genotypes dry regions of Iran
These descriptive data will and cultivars, morphological characterization be useful for identifying melon accessions in has been done by several studies for local this collection of germplasm, determining germplasms and indicate different genetic melon accessions which have the best sources[2]
