Abstract : Mangoes are economically important for Mozambique because of adequate climatic conditions and international market opportunities. This study compare morphological and AFLP characterisation of 30 mango varieties from the Umbeluzi research station, including some commercial varieties. The total variation was lower using quantitative (89.4% similarity) than qualitative data (60% similarity). The combined quantitative and qualitative dendrogram had a total variation of 63% similarity and clustered varieties in three subgroups based on high fruit weight, high Brix content and low fruit weight. AFLP characterisation used seven primers combinations, generating 207 data points and detecting 74.9% polymorphisms with an average of 30 fragments per primer combination. The total variation was low (72.49% similarity) and the dendrogram showed five subgroups based on low fruit weight, dwarfness and low Brix content, commercial varieties, high fruit weight and roundish fruit shape. The combined morphological and AFLP dendrogram was more accurate in clustering varieties based on geographic origin within the country and from outside.
