This research was mainly to assess the genetic similarity and genetic distance ofthree indigenous Sudanese cattle breeds (Erashy, Butana and Kenana). Six arbitrary primers were used to detect DNA polymorphisms. Two hundred and twenty nine fragments were amplified. A high level of genetic variation was observed among and within population studied. Genetic distances between populations ranged from 0.59 to 0.64. Results of phylogenetic analysis indicated that Erashy cattle breed is genetically closer to Butana cattle breed than to Kenana cattle breed. The study also concluded that such high level of genetic differentiation within Sudanese cattle populations leads to the speculation that they might belong to different breeds despite their having the same name and similar morphological traits. This study recommended that genetic characterization of these populations needs to be clarified in the future by more specific molecular techniques.
