The analyses of variance revealed the existence of variability for most evaluated morphoagronomic traits. Clustering by Tocher's optimization method for the morphoagronomic traits of Campos dos Goytacazes formed eight groups and 16 for those of Itaocara. For the RAPD markers, 18 groups of S1 families were formed by Ward's clustering method. It is concluded that there is genetic divergence in the selected families, which allows the inference that there is sufficient variability for the continuity of the recurrent selection process with the formation of new cycles..  apopcorn  arecurrent selection  aMarcador Genético  aMilho Pipoca  aMorfologia Vegetal  aSeleção Recorrente  aVariação Genética  aZea Mays  aDiversidade genética  aGenetic variability  aInteração genótipo por ambiente  aInteraction genotype by environment  aMilho de pipoca  aVariabiidade genética1 aAMARAL JUNIOR, A.
