Abstract
The diversity of 51 representative populations of the 5 Aegilops species from Moroccan collection was analyzed using 22 RAPD primers. We investigated the associations among these 5 Aegilops species (A. geniculata Roth (UUMM), A. triuncialis L. (UUCC), A. ventricosa Tausch (DDNN), A. peregrina (Hackel) Maire et Weiller (UUMM) and A. neglecta Req. ex Bert. subsp. recta (Zhuk.) K. Hammer (UUMMNN)); some diploid species considered as their ancestors; accessions of some neighboring countries and also accessions of Triticums. A total of 650 polymorphic RAPD fragments were amplified. A dendrogram was constructed using the un-weighed pair group method arithmetic average (UPGMA) and Jaccard`s similarity coefficient. The UPGMA clustering showed a regrouping to the level species with high level of the structuration of the diversity at A. geniculata. We confirm as reported by other authors, the proximity of N genome to U genome and C genome to M genome and also the difference between the genomes M and N. Thus, the phylogeny between the species and the different genomes were retracted.
