Fig. 1From: Phenotypic variation and genome-wide association studies of main culm panicle node number, maximum node production rate, and degree-days to heading in riceFrequency distribution and pairwise correlations of main culm panicle node number (MCPNN), maximum node production rate (MNPR), and degree days to heading (DDTH). The diagonal shows the histograms of the three traits. Shown below the diagonal are pairwise scatterplots. Shown above the diagonal are the pairwise Pearson correlation coefficients among MCPNN, MNPR, and DDTH. ***Significant at p = 0.001Back to article page
