To compare the performance of certified (F1) vs retained (F2) generations of an open-pollinated and hybrid canola variety at different plant densities.
The hybrid canola 44Y84 (both certified and retained generations) yielded better than the open-pollinated variety 43C80, by an average of 0.3t/ha (20%). The hybrid established better than the OP variety. On average, 40% of seeds established as plants and plant densities above 20 plants/m2 maximised grain yield. The use of certified seed for both open-pollinated and hybrid canola did not increase yields compared with retained seed for both hybrid and open-pollinated. However, view results with caution as the variability within the trial was high.
