Abstract excerpt

The tetraploid species Avena agadiriana that was first described in 1985 is distributed on the Atlantic coastal strip south of Casablanca in Morocco. Five accessions of this species (M55, M59, M60, M71 and M74) were compared by using FISH and RFLP analysis of 18S-5.8S-26S rDNA. The FISH data indicated that three pairs of major hybridization sites of the rDNA were located on satellite chromosomes in accessions...
