Abstract: | Thirty pomegranate (Punica granatum L.) accessions were studied to determine the overall degree of polymorphism and to detect similarities among genotypes. PCA and cluster analysis showed a considerable phenotypic and genetic diversity in the local pomegranate germplasm. Some polyclonal varieties were identified and cases of homonymy were detected. The geographic origin was not a determinant criterion for cultivars clustering. Parameters with high discriminating values were those related to fruit size and color and juice characteristics. Factors affecting pomegranate germplasm diversity are discussed. |
