Fig. 5. Significant additive, additive x additive, and additive x additive x additive effects among genetic marker loci (B, P, Hyp, ORS371, ORS188, ORS1068, and ORS484) for seed length, width, and depth in the RHA280 x RHA801 recombinant inbred line mapping population, where a = (y_{RHA801 –} y_RHA280)/2 is the additive effect, y_RHA801 is the least square mean for genotypes homozygous for the RHA801 allele, y_RHA280 is the least square mean for genotypes homozygous for the RHA280 allele, and the significance threshold for Type III F tests was p 0.05.
