The aboveground morphogenesis is an important basis of plant morphological construction and visualization for winter wheat before overwintering. For quantitatively analyzing the relationship between the aboveground architectural parameters and organ biomass of winter wheat before overwintering, field experiments with different varieties (Jimai 22, Tainong 18, and Luyuan 502) and nitrogen levels were carried out in 2013–2014 and 2014–2015 wheat growth seasons. Simulation models for aboveground architectural of winter wheat before overwintering were built with the 2013–2014 dataset of aboveground architectural parameters before overwintering and organ biomass and validated by the2014–2015dataset, showing the models exhibited satisfactory predictions for leaf blade length, leaf maximum blade width, leaf blade tangent angle, and leaf blade bowstring angle, except for leaf sheath length and leaf bowstring length. The models built in this study are suitable to simulate the aboveground architecture of winter wheat varieties before overwinteringunder different nitrogen levels.
