The genus Phoenix (Arecaceae) comprises 14 species distributed from Cape Verde Islands to SE Asia. It includes the economically important species Phoenix dactylifera. The paucity of differential morphological and anatomical useful characters, and interspecific hybridization, make identification of Phoenix species difficult. In this context, the development of reliable DNA markers for species an...

The quantitative study of genetic diversity requires tools to describe quantitatively and in parallel the whole phenotypic order produce meaningful comparisons. genus Phoenix offers examples species with very different levels or heterogeneity. Within Phoenix, date palm (Phoenix dactylifera L.) is a major food crop global relevance. concept information entropy was introduced by Claude Shannon; a...
