Frequency and expression of Hd1 haplotypes in 123 major rice varieties cultivated in China. (a) Allele frequencies of 19 Hd1 haplotypes among the three time period groups. Darker grey rectangles indicate indica haplotypes, and white rectangles indicate japonica haplotypes. (b) Allele frequencies of five major haplotypes among the three stages. Pink, red, brown, light blue, deep blue and white indicate haplotypes 14, 15, 16, 8, 13, and all other haplotypes, respectively. (c) The expression of five major haplotypes among the three stages.
