Fig. 3. Genotype class means for CGA and flavones at the marker genotype nearest the qtl2 locus in A: (A619 x Mp708)F₂ and B: (A619 x Mo6)F₂ populations. Genotype A, homozygous A619 alleles; H, heterozygous; and B, homozygous Mp708 or Mo6 alleles depending upon the population. Standard error bars are taken to the second standard deviation.
