| Abstract:
Phenetic relationships among seventeen pomegranate (Punica granatum L.) cultivars maintained at ISA Chott-Mariem collection were surveyed using morphological and amplified fragment length polymorphism (AFLP) markers. Twenty-four quantitative and five qualitative parameters related with leaves, flowers and fruits were studied. The derived UPGMA dendrogram was compared to the one based on AFLPs. Results proved that a large phenotypic variability and high level of molecular polymorphism in the local pomegranate germplasm. In addition, correlation between distance matrices was assessed using the Mantel test. Therefore, AFLP and morphometric data are significantly correlated (r = 0.454, p-value<0.05) suggesting that the studied cultivars constitute an important source of genetic diversity useful in future breeding programs. The present study portrays opportunities for the use of AFLP-markers together with morphological traits to characterize pomegranate cultivars and to manage the conservation of pomegranate genetic resources. | |
