Supplementary Figure 3: The semidominant qGW7 allele from TFA was correlated with the formation of more slender grains.

(a) Segregation of the BC1F2 population derived from TFA and HJX74 (recurrent parent). (b–d) Comparisons of grain width (b), grain length (c) and ratio of grain length to width (d) among homozygotes for the TFA qGW7 allele, heterozygotes for the TFA qGW7 allele and the HJX74 qgw7 allele, and homozygotes for the HJX74 qgw7 allele. Data are shown as means ± s.e.m. (n = 120). The same lowercase letter denotes a non-significant difference between the means (P > 0.05).
