Fig. 3

Principal component analysis of 220 diverse rice accessions used in genome-wide association studies (GWAS) for main culm panicle node number (MCPNN), maximum node production rate (MNPR), and degree days to heading (DDTH), showing (a) PC1 by PC2, and (b) PC2 by PC4. IR64, Nipponbare, and Presidio are labeled as representatives of the indica, temperate japonica (TEJ), and tropical japonica (TRJ) subgroups, respectively.
