Fig. 1From: Phenotypic and molecular characterization of a set of tropical maize inbred lines from a public breeding program in BrazilHeat map of Pearson correlation coefficients between pairs of vectors of genotypic values of the traits measured in this set of tropical maize lines across four environments. The color assigned to a point in the Heat map grid indicates the strength of a correlation between two traits. The level of correlation is indicated by red for positive correlations and blue for negative correlations, as depicted in the color key. * Significant at P = 0.05Back to article page
