Fig. 1From: Genetic analysis of three maize husk traits by QTL mapping in a maize-teosinte populationFrequency distributions and correlation coefficients of three husk traits using BLUP values. Plots along diagonal line depict phenotypic distribution of each trait. Values above diagonal line are Pearson’s correlation coefficients between traits. Plots below diagonal line are scatter plots of compared traits. **Significant at P ≤ 0.01Back to article page
