Este trabalho teve por objetivo utilizar marcadores moleculares de DNA (RAPD), para analisar a diversidade genética entre 16 linhagens elite de milho e estimar a correlação entre a distância e o desempenho de híbridos. Vinte e dois primers aleatórios resultaram na amplificação de 265 fragmentos, dos quais 237 (84,44%) foram polimórficos. A partir dos marcadores RAPD, uma matriz de similaridade genética foi gerada, tendo-se usado o coeficiente de Jaccard, e um dendrograma foi construído. Para a avaliação dos híbridos resultantes dos dialelos, utilizaram-se blocos ao acaso e o método IV de Griffing. As associações genéticas obtidas mostraram cinco padrões heteróticos distintos. As correlações entre as divergências genéticas, detectadas por RA...
