Distribution of five yield-related traits in rice and Pearson coefficient analysis. The lower left represents the linear regression statistics between each two traits, the diagonal histogram represents the distribution of each trait, and the upper right number represents the correlation coefficient (positive numbers represent positive correlation, negative numbers represent negative correlation); asterisks represent significance (* stands for p-value less than 0.05; *** stands for p-value less than 0.001); yellow circles indicate that the absolute value of the correlation is greater than 0.5, and blue represents less than 0.5
