DNA variation and polymorphism in Tunisian plum species (Prunus spp): contribution of flow cytometry and molecular markers
Plums (Prunus spp) are among the most important stone fruit crops in the world. European (Prunus domestica) and Japanese (Prunus salicina) plums are characterized by different levels of ploidy. Because genetic variability is the prerequisite for any plant-breeding program, we aimed to establish the taxonomic status of Tunisian plums and study their genetic variability. The nuclear DNA content of 45 wild and cultivated Tunisian plums was determined by flow cytometry.
