• The choice of most suitable canola variety for any situation will often follow a consideration of maturity, herbicide tolerance, blackleg resistance and early vigor together with relative yield and oil content.
• The weed species expected may dictate the need for a herbicide tolerant production system (e.g., triazine tolerant or Clearfield). Remember that a triazine tolerant variety will incur a yield and oil penalty when grown in situations where they are not warranted.
• Varietal blackleg resistance and/or fungicide use should be considered, particularly when rotations are close.
• Variety selection should be made inconjuction with the latest version of the blackleg risk assessor (available at www.grdc.com.au).
• Growers should be encouraged to change canola varieties every two or three years to reduce the risk of blackleg.

• Latest information on canola variety yield performance can be found at www.nvtonline.com.au.

Introduction

Due to the high levels of blackleg in many areas in SA, it is very important that canola crops are grown at least 500 metres away from last year’s canola paddock. Also, if you have used the same variety for three years or more there is an increased chance of blackleg that can attack that variety. Therefore it is even more important to keep the same variety at least 500 metres away from stubble of that variety.

Previously all canola trials were sown with bare seed, but NVT trials in 2011 and 2012 have been sown with the same fungicide treatment (Impact-in-furrow®) on all varieties so that the reaction to blackleg will be more difficult to assess from looking at the trials.

Research over the past several years has shown that canola varieties that are grown very intensively in a given region can have their blackleg resistance reduced. This is because a blackleg race can develop that can overcome this varietal resistance. It is recommended that growers should rotate canola varieties or change them after a couple of years to reduce this occurring. We have developed the Blackleg Risk Assessor to help farmers and consultants to understand the factors that assist blackleg to overcome resistance and how to manage it. This publication is available at www.grdc.com.au.

There has been a wide range of new varieties available for 2012 sowings. Many of these varieties are hybrids and the likelihood is that in future many more hybrids will be released. When you make your choice about new varieties you should rely on NVT data from the NVT website and any of your own ideas from observing trials in 2012. The new blackleg ratings will be released in early March and will be available on the Australian Oilseeds Federation website: www.australianoilseeds.com
