The Genetic Diversity Analysis of Tunisian Male Date Palm Cultivars (Phoneix dactylifera L.) Revealed by Phenotypic and Molecular Markers

Tunisian oases reveal an important genetic heritage of date palm cultivars, with various qualities use. Since the beginning century, this has evolved to a selective orientation based on monoculture "Deglet Nour," risks causing loss many cultivars. The male is part and so far remains marginalized. Although they are for production cycle, it in context that lies our work study diversity collection pollinators from southern Tunisia. morphological 20 using 45 IPGRI (International Plant Genetic Resources Institute) descriptors showed significant discrimination, similarity index ranging 0.207 0.457, divided them into five groups. use 7 ISSR (Inter Simple Sequences Repeat) primers resulted 64 reproducible bands, which 57 were 90% polymorphic, statistical analysis more or less distances 0.491 0.873. According Mentel test, non-significant weak correlation (r = 0.015) was noted between molecular data. However, processing data by methods generated very correlations. Indeed, SM (Simple matching) coefficient DICE r 0.748, confirms discriminating power markers studying pollinators.
