It points toward the potential role played either by environmental conditions or local selection practice. Heatmaps of genetic versus morphological and agronomical characters in date palm cultivars differed from each other showing the cultivars morphological changes is not merely related to their genetic content. Test of assignment revealed that some of the cultivars have 33-66% misassignment, probably due to genetic admixture. New genetic differentiation parameters estimated also produced significant difference among date palm cultivars (G’st (Nei) = 0.673, P = 0.001 G’st (Hed) = 0.738, P = 0.001). AMOVA produced significant genetic difference among date palm cultivars (PhiPT = 0.70, P = 0.001). This was supported by delta K = 2 of the STRUCTURE analysis.
K-Means clustering grouped date palm cultivars either in two broad clusters, or in 16 smaller genetic groups. The most of SSR loci obtained have a high Gst value (0.70), and therefore have a good discrimination power for date palm cultivar differentiation task. We used nine SSRs and EST-SSR loci for our genetic investigation. Therefore, the present study was performed with the following aims: 1- To provide data on genetic diversity and genetic structure of 36 date palm cultivars, 2- To provide data on the association between fruit characteristics and the genetic features of the cultivars. For future breeding program, knowledge on genetic structure of cultivars is necessary.
