Fig. 6. Observed vs. estimated data for oleic acid and linoleic acid concentrations for the traditional hybrids (a and b) ACA 885, (c and d) DK 3915, and (e and f) VDH 488. Estimated values for a, c, and e were calculated based on the function presented in Fig. 2 and for b, d, and f based on functions shown in Fig. 3a. Dotted lines represent y = x and solid lines show the linear regression between observed and estimated values.
