Trait analysis of the RDP1 diversity panel. a Correlation analysis of four grain size traits at two locations, Shanghai and Hainan, China. The correlation coefficients are illustrated both by the circle size and color gradient ranging from 1 to −1. Red and blue colors denote positive and negative correlations, respectively, and darker colors and larger circles correspond to greater correlations between traits. b-e Grain trait measurements between indica and japonica subspecies at two locations. *, ** and **** indicate significance at P < 0.05, P < 0.01 and P < 0.001 by Student’s t test, respectively
