Resumo: The knowledge of the genetic and phenotypic variability among different accessions of guava is important for supporting improvement programs of this specie in northern Rio de Janeiro state, which needs new cultivars able to generate income for local farmers. This work aimed to evaluate the genetic divergence among six cultivars and 19 accessions of guava via RAPD molecular markers and morphological characteristics. One hundred and seventeen polymorphic markers were obtained from 28 primers. The results showed a partial agreement between the methods of studied groupings, with the formation of 12 groups. The accessions ‘Vita 3’and ‘6’ were the most divergent, showing genetic distance of 0.663. The comparative analysis of groupings showed that RAPD markers and morphological descriptors were effective in discriminating the accessions and to show potential genetic variability useful in genetic improvement programs.

O objetivo deste trabalho foi avaliar a divergência genética entre seis cultivares e 19 acessos de goiabeiras, por meio de marcadores moleculares RAPD e características morfoagronômicas. Foram obtidas 117 marcas polimórficas, utilizando-se 28 iniciadores. Os resultados mostraram uma concordância parcial entre os métodos de agrupamentos estudados, com a formação de 12 grupos. O acesso Vita 3 e o acesso 6 foram os mais divergentes, apresentando distância genética de 0,663. A análise comparativa dos agrupamentos revelou que os marcadores RAPD e os descritores morfológicos foram eficientes para discriminação dos acessos e que houve variabilidade genética potencial para uso em Programa de Melhoramento Genético.Universidade Estadual de Maringá2010-11-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa de campo e laboratórioapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/472010.4025/actasciagron.v32i4.4720Acta Scientiarum.
