Morphological characterization and genetic divergence of creole maize populations of the Alto Vale do Jequitinhonha

The objective of this work was to evaluate morphological differences and genetic divergence among the Creole corn so that they can serve for the cultivation of producers in the region of Couto Magalhaes de Minas MG. The experiment was conducted at the Rio Manso Experimental Farm, Federal University of the valleys of Jequitinhonha and Mucuri, during the 2017/18 harvest, being studied six varieties of Creole corn, two improved varieties and two commercial varieties. Thirteen characteristics were evaluated: leaf, stem and flowering. The varieties of Creole corn showed genetic divergence, being generally discriminated by the genetic origin and the morphological characteristic that contributes most to the divergence is the mean height of the spike insertion.
