提出了一个模型来表征一组固定品种、品种杂交以及从这些品种和品种杂交获得的其他条目的平均值。这些品种可以是纯系品种、具有任何程度的近交的自交系以及开放授粉或合成品种，只要品种处于Hardy-Weinberg平衡即可。假设二倍体遗传，参数被定义为加性、显性和加性上位效应的加性。可以通过对由于高阶上位性（和/或通过加性上位性与加性上位性联系）引起的偏差进行方差分析来进行测试。如果模型足够，则可以预测相关条目的性能。在某些情况下，预测平均值的方差将小于观测平均值的方差。 [该模型应用于玉米双列基因。]。
A model is proposed to characterize the means of a fixed set of varieties, variety crosses and other entries obtained from these varieties and variety crosses. The varieties can be pure-line varieties, inbred lines with any degree of inbreeding as well as open-pollinated or synthetic varieties as long as the varieties are in Hardy-Weinberg equilibrium. Parameters are defined for additive, dominance and additive by additive epistatic effects assuming diploid inheritance. Tests are available from the analysis of variance for deviations due to higher order epistasis (and/or linkage with additive by additive epistasis). If the model is adequate, the performance of related entries can be predicted. In certain instances, the variance of the predicted mean will be less than the variance of an observed mean.
