The objective of the present work was to analyze the genetic diversity between 20 guava access (UENF 1830 - UENF 1849) Universidade Estadual do Norte Fluminense - UENF. The genetic dissimilarity was studied using RAPD molecular markers. Twenty eight primers were used, generating a total of 157 bands. The RAPD molecular markers were capable to accurately reveal the existence of diversity among the 20 guava accesses. For data interpretation, the Nei Li. index was used. Based on cluster analysis UPGMA and Tocher, the dissimilarity could be observed by the presence of similar and dissimilar access.
