Grain yield responses of durum and hard red spring wheat cultivars to varying sowing densities.

 


Fig. 3.

Biplot (mean vs. CV) of variety and sowing density combinations for data from insect-related variables collected at Coalhurst and Nobleford, AB, Canada, 2006 to 2009. The prefix of the labels indicates the variety selected followed by the planting density (150, 250, 350, or 450 seeds m−2).
