  • The distribution of mutant vs. wild-type Wx alleles is significant in a chi-square test (χ2 = 33.721, d.f. = 4, P < 8.5 × 10−7) for the three major variety groups (indica, tropical japonica, temperate japonica); aus and aromatic varieties were excluded from the statistical test because of small sample size.
