Résumé partiel
Egypt is famous for its vast desert spaces. About 4/5 the total area is desert. Only about one-fifth of the total area is cultivated land. In the western desert of Egypt there are a series of oases which stretching longitudinally from the north to the far south in a line almost parallel to the Nile valley. This represents natural depressions rich in natural springs and wells which are used in agriculture. One of the advantages of this desert is the presence of wild flora species adapted to a biotic and biotic stresses. Despite the rarity of wild plant cover in such region, this existing flora is a treasure of genetic resources. Most of these flora species are considered as the ancestors of domesticated plants, others have medicinal benefits either on the popular level or on the documented medicinal treatments The Genetic description and phylogeny of some Egyptian Acacia species and subspecies was investigated in present study by calculating the morphological variation among Acacia species, detecting biochemical markers based on peroxidase activity and proline content in Acacia species, estimate the level of polymorphism among Acacia species using RABD-PCR markers and determining the genetic relationships between these species based on the genetic distances. The present research was carried out at the Faculty of Agriculture, Saba Basha, Alexandria University and Faculty of Agriculture, Ain Shames University, Egypt during the seasons of 2011 up to 2013 to study the morphological, biochemical and molecular genetic markers of some selected Acacia genotypes as a tool for genetic description for these genotypes.
