Based on ACAS protocols, this
blackleg resistance rating system is compiled from data supplied
by all canola breeding programs and associated pathologists
throughout Australia. This national system is based on the most
up to date data available and will ensure consistent ratings for
Australia.
Ratings are calculated using the
official CAA methodology, which has strict protocols to ensure
accuracy of the data collected. All results are analysed by an
independent biometrician.
Blackleg resistance is one of
several key selection criteria to be considered in choosing the
most appropriate canola variety for your farm.
Growers should consider:
- Maturity -match variety
maturity class (early or mid) to your expected growing
season length.
- Herbicide tolerance -know
your weed spectrum to determine if you require a triazine
tolerant (TT) or Clearfield™ system canola variety.
- Economic return -check
Dept of Agriculture and private company trial results for
yield and oil content.
- Blackleg resistance
-identify the varieties which fit the above criteria and
then choose the variety with the highest possible blackleg
resistance rating.
