RAPD molecular markers were used to analyze genetic diversity between 16 corn lines. Twenty-two primers were used resulting in the amplification of 265 fragments, of which 237 (84.44%) were polymorphic. Using the UPGMA method the genetic associations obtained showed 5 distinct heterotic groups. A principal coordinates analysis also showed an association of lines in 5 groups, in agreement with the results observed in the dendrogram. A bootstrap procedure was applied to verify whether the amountdoi:10.12702/1984-7033.v07n02a09 fatcat:ntp376rn7fgqjojue4t3lshk24
