Fig. 5. Observed vs. estimated data for (a) oleic acid concentration and (b) linoleic acid concentration for the traditional hybrid DK 3881. Oleic and linoleic acid concentrations were calculated based on the function presented in Fig. 2 and 3a, respectively. Observed values correspond to Exp. GC6 (circles) and FB7 and FP1 (triangles). Dotted lines represent y = x and solid lines show the linear regression between observed and estimated values.
