| Résumé: | Genetic variation among 43 date palm (Phoenix dactylifera L.) accessions, including 37 accessions from Morocco
and 6 cultivars from Iraq and Tunisia, was studied using Random Amplified Polymorphic DNA (RAPD) markers.
The pre-screening of 123 primers on four genotypes allowed selection of 19 primers which revealed polymorphism
and gave reproducible results. All 43 analysed genotypes were distinguishable by their band patterns. RAPD technology
therefore appears very effective for identifying accessions of date palm. RAPD-based genetic distance was
used to determine the relationships between the accessions. The grouping-association identified by cluster analysis
was rather weak. However, morphologically similar varieties clustered together. A relatively low polymorphism
and a lack of evident organisation are observed among the date palm varieties grown in Morocco. This could
be related to the mode of introduction and maintenance of the Moroccan date palm germplasm involving limited
foundation germplasm, exchange of cultivars between plantations, and periodic development of new recombinant
cultivars following sexual reproduction. |
