  abstract = {{M}ost male date palms available for pollinating different female cultivars have mainly originated from seed propagation resulting in many different local males that represent a source of genetic diversity. {F}avourable fruit production is related to the quality of pollen and its compatibility with a certain female variety. {T}herefore, the genetic characterisation of the male progenitors should be the first step to establish a selection programme to produce superior males through different procedures. {I}n this study, the genetic diversity and population structure of 72 male date palm accessions were investigated using 15 microsatellite loci. {T}he highest mean number of alleles per locus was obtained for {T}ozeur group. {B}ayesian model-based clustering analysis indicated the presence of two differentiated endemic male date palm genetic clusters, continental and insular, with the presence of introduced accessions originating from the {M}iddle {E}ast. {T}he diversity analysis in the insular region of {T}unisia, which had never been performed before, revealed that this germplasm enclosed valuable endemic resources supporting the hypothesis of the presence of wild material. {T}hese findings are crucial for identifying interesting genotypes that can be integrated into international coordinated actions of {P}hoenix dactylifera {L}. breeding programmes and the protection and conservation of valuable resources.},
