Strawberry cultivars introduced in Brazil were identified through molecular study. The method of Random Amplified Polymorphic DNA (RAPD) was used. Molecular characters with larger discrimination power were produced by the primers Operon B8, Operon B19 and Operon G5. These were efficient to discriminate the twenty six studied cultivars. Data were analised through dendogram, bandmap, picture and dicotomic key. Six similarity groups were distinguished: Two with cultivars selected in Brazil, one with 'Campinas', 'Agf 80', 'Piedade', 'Jundiaí' and 'Monte Alegre' and the other with 'Obaira' and 'Mantiqueira'; three with introduced cultivars the first of which 'Lassen', 'Reiko', 'Chandler', 'Pajaro', 'Blackmore' and 'Seascape', the second with 'Fern' and 'Oso Grande' and the third with 'Florida Belle' and 'Selva'. The last group united the cultivars 'Dover' and 'Dabreak' with 'Princesa Isabel'.
