The genetic diversity of 14 watermelon [Citrullus lanatus (Thunb.)] accessions collected from Palestine were morphologically characterized using 37 descriptors. Data were analyzed considering the genotypes, years and year*genotype interactions for the two years 2014 and 2015. The statistical uncertainty of resulting hierarchical cluster groups was determined by calculating approximately unbiased p-values using Genstat program. Cluster analysis indicated that 14 accessions divided into three major clusters. A maximum genetic similarity was observed between accession numbers 9 from Arabeh and 17 from Meithalon, which revealed a high degree of similarity to the extent of 95% existing between them. Whereas, a minimum genetic similarity was observed between accession number 7 and 15 from Meithalun, which showed 60% similarity. The results also showed that, based on agronomic measurements significant variation (P > 0.05) among accession were found for fruit yield, number of seeds per fruit. Accession number 3 was the highest for fruit yield and accession number 20 have the highest number of seeds per fruit. This information on variation and relationships among the morphological traits will be helpful for selection strategies in local and international breeding programs.
