Phenotypic characteristics for discrimination between advanced genotypes of Brachiaria ruziziensis

Genetics and Molecular Research, 2016
The aim of this study was to use multivariate methods and Pearson and partial correlations to disregard phenotypic characteristics that contribute little to differentiation between Brachiaria ruziziensis genotypes. Eighty-one genotypes of B. ruziziensis were assessed in completely randomized blocks with three replications.
