The genetic variability among the 14 Citrus accessions was estimated using forty decamer RAPD primers. The total number of amplicons detected was 531, including 349 polymorphic amplicons. This represents a level of polymorphism of 65.7% and an average number of 8.7 polymorphic bands per primer. RAPD markers detected genetic similarity ranging from 10.8% to 87.7% between TC and each of WM, A WM and BSO and between MSG and RRG, respectively. The similarity matrices were employed in the cluster analysis to generate a dendrogram using the UPGMA method. The dendrogram separated Troyer citrange from the other Citrus genotypes. Moreover, accessions belonging to the same species always clustered together UR - http://nile.enal.sci.eg/EALE/2004/AJB/704/1/23.pdf ER -
