Fig. 4. Genotype class means for CGA and flavones of markers nearest to p1 and qtl2 from A: (A619 x Mp708)F₂ and B: (A619 x Mo6)F₂ populations. Genotypes of p1 are represented by the bottom row of letters, and subdivided into qtl2 genotypes where A, homozygous A619 alleles; H, heterozygous alleles; and B, homozygous Mp708 or Mo6 alleles dependent upon the population. Standard error bars are taken to the second standard deviation.
