Fig. 2. Starch (A), protein (B) and oil (C) content per kernel (mg kernel^-1) in relation to kernel weight (KW; mg kernel^-1) for hybrids DK664 and DK752. The gray dotted lines within each graphic show the concentration of the component as reference. Inserts within each figure show the parameters ± the standard error of the fitted linear and bilinear models.
