Fig. 2.

(A) The proportions of landrace and improved rice accessions in the three RM4108 allele groups. Landraces are shown in white and improved rice accessions in gray. Numbers in each circle indicate the number of accessions in each group. (B) Frequency distributions for principal component 1 (PC1), protein content, amylose content, eating quality, maximum viscosity, and stickiness on the grain surface and of the whole grain for the 146 non-glutinous temperate japonica rice accessions. Rice accessions of the RM4108-A, B, and C allele groups are shown in black, gray and white, respectively.
