Breeding companies are favouring the development of hybrids in order to pay for breeding services.
Hybrids provide growers with more vigorous seedlings, comparatively better plant establishment and generally higher yields, however, growers have to purchase new seed of hybrid varieties every year in order to get these potential yield benefits.
Seed for hybrid canola is 10 to 25 times more expensive than the seed of open pollinated canola.
If growers are forced into hybrids they may wish to minimise seed costs by sowing at lower densities.
To investigate the plant density response to yield and oil content of TT and RR hybrid canola in comparison with open-pollinated canola.
