Retaining hybrid canola locations
Aims

To determine the yield penalty for retaining hybrid canola varieties in different yielding and disease environments (Mallee and Wimmera).

Key messages

Retaining hybrid canola from one season to the next incurred a yield penalty of 0.3t/ha at Quambatook. There was a general penalty of 0.2t/ha for retained seed in the mean yield of all varieties (including OPs) at Horsham. Oil content and test weights of retained seed were lower at Quambatook, but not at Horsham. Retaining hybrid seed compromises plant vigour, disease resistance and herbicide tolerance. The yield advantages (0.2-0.3t/ha) from hybrid varieties, particularly within the Clearfield hybrid varieties, significantly outweigh the initial seed cost of $44/ha at 2kg/ha sowing rate.
