Abstract : Thirty-eight mango cultivars and one wild mango species (Mangifera persiciforma) were examined using random amplified polymorphic DNA (RAPD) markers. PCR [polymerase chain reaction] amplification with 19 primers generated 223 bands, 87.89% of which were polymorphic. The results suggested the presence of high genetic diversity among the cultivars. Based on the UPGMA [unweighted pair-group method with arithmetic averages] dendrogram, the 38 cultivars were classified into 3 groups (similarity coefficient of 75.5%), the classification of which was significantly correlated with embryo type. One marker associated with skin colour, and several markers associated with embryo type in mango were identified. The pedigree of several cultivars, and the inheritance of embryo type and fruit skin colour are described.
