Diversity analysis of Aegilops species from Morocco using RAPD markers

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.
