Epistasis plot of effects for Rht-1B and Rht-1D linked markers on PH in 158 RIL lines derived from NY91017-8080 $\times$ Caledonia. The filled circles indicate the intercept (i.e., reference point) for each model parameterization while open circles indicate genotype class means. The solid lines indicate the marker effect estimates including the interaction term, while the dotted line indicates the expectation based on the additive model. (A) $\left\{0,1\right\}$marker coding with positive marker effect orientation. (B) $\left\{0,1\right\}$marker coding with negative marker effect orientation. (C) $\left\{-1,1\right\}$marker coding with positive marker effect orientation, (D) $\left\{-1,1\right\}$ marker coding with negative marker effect orientation.
