Canola Overview 2009
Plenty more canola varieties for 2009 season
By Trent Potter,
SARDI, Struan
Sowing for the 2008 season began relatively early at most sites with generally good early growth. However, the very dry spring resulted in much reduced grain yields at several sites.
As well, variety maturity played an important part in grain yield with earlier flowering varieties performing well. In many cases, hybrids with greater early vigour, produced a large amount of growth but could not then fill grain and grain yields were below expectations.
Over the whole state, blackleg was observed at lower levels than in the past five years or more. There was little internal infection noted when plants were cut in the NVT trials (Tables 1 and 2).
However, in a trial conducted in the South East, the amount of yield loss due to blackleg was twice as much as had been measured in a season with a good spring (2001).
Therefore blackleg still reduced grain yields significantly in some circumstances. The blackleg rating system for all canola varieties has been changed from the numerical one to a descriptive scale, conforming to the systems used for other major winter crops.
The new CAA blackleg ratings for 2009 are included in varietal descriptions in this document.
Highest yielding conventional varieties were AV-Garnet and Hyola50. Varieties such as AV-Sapphire are now significantly lower yielding than the above varieties.
At the earlier maturity sites, CB™Tanami, BravoTT, TawrifficTT and ATR-Cobbler produced reasonable yields. At the mid season sites, BravoTT also gave high grain yields, due to being an early-mid maturity variety.
In the mid north and Yorke Peninsula, other high yielding TT varieties were Monola77TT and ATR-Cobbler. In the South East and lower Eyre Peninsula, TornadoTT and ThunderTT also produced high yields. The TT hybrid Ttriumph Jardee was only tested at Bordertown and Yeelanna. At Bordertown it was the highest yielding TT variety but requires further testing in 2009.
Highest yielding Clearfield varieties over most sites were Hyola571CL and 46Y78. 46Y81 also produced good grain yields in the South East.
Varieties released in 2008 but mainly commercial in 2009
CLEARFIELD (imidazolinone tolerant) varieties
44C79. New release (coded NS6082BI). Early maturing, similar to 44C73. Pioneer indicate good vigour, high yield and oil content. Blackleg rating MR-MS (provisional). Targeted to replace 44C73. Limited release in 2008. Only in NVT trials in 2008. Bred and marketed by Pioneer Hi-Bred Australia.
Juncea canola

Limited seed quantities for 2009. Bred by DPI-Victoria and Viterra (Canada). Marketed by Pacific Seeds. An EPR applies.
New varieties for 2009
A number of new varieties will be marketed for 2009 sowings. Information about new varieties has been provided by the seed companies as in most cases, entries have only come into NVT trials in 2008.
Conventional varieties
V3001 (tested as 06H932)
Early to mid maturing specialty hybrid developed by Cargill and Vic. DPI. Good blackleg resistance (R-MR) and yield potential and has performed well in 2007 and 2008 NVT trials. V3001 will be grown under contract production for Cargill and marketed by Pacific Seeds.
V3002 (tested as 06H939 )
Mid maturing specialty hybrid developed by Cargill and Vic. DPI. Good blackleg (R-MR) and yield potential and has performed well in 2008 NVT trials. V3002 will be grown under contract production for Cargill and marketed by Pacific Seeds.
Triazine tolerant (TT) varieties
CB™ Argyle Mid season maturity. CBWA indicate the variety to be high yielding, with high oil and moderate protein content. Blackleg rating MR. Tested in SA NVT in 2007 and 2008. Bred by CBWA; marketed by ABB Seeds in eastern Australia. An End Point Royalty (EPR) applies.
Monola™ 76TT (tested as NL042). Mid maturing Monola™ variety. Nuseed Crop Network indicates high yielding with moderate-high oil content. Medium high with excellent uniformity. Blackleg resistance R-MR. Tested in NVT in 2008. Developed by Nuseed, grown under contract with a premium to Nuseed Crop Network.
Monola™ 77TT (tested as NL045). Mid maturing Monola™ variety. Nuseed Crop Network indicates high yielding with moderate-high oil content. Medium high with excellent uniformity. Blackleg resistance MR. Tested in NVT in 2008. Developed by Nuseed, grown under contract with a premium to Nuseed Crop Network.
TTriumph Jardee
First TT hybrid canola. CBWA indicate moderate to high blackleg resistance (MR) and excellent early vigour. Small amounts of seed may be available in 2009. Tested in NVT trials in 2008 at a few sites only. Bred by CBWA; marketed by ABB Seeds in eastern Australia.
CLEARFIELDŽ (imidazolinone tolerant) varieties
43C80 (coded NS6108BI). Early maturing variety. Pioneer indicate good early vigour, good yield and moderate oil content. Blackleg rating MS (provisional). Suited to low rainfall areas and potentially as a late sowing option in medium-high rainfall areas. Tested in NVT trials in 2008. Limited seed quantities in 2009. Bred and marketed by Pioneer Hi-Bred.
46Y81 (coded NS05N289I). Mid season hybrid, intermediate maturity between 45Y77 and 46Y78. Pioneer indicates exceptional early vigour, with high oil content. Anticipated blackleg resistance R-MR.
Will replace 46C76, and possibly 45Y77 and 46Y78. Tested in NVT trials 2007 and 2008.
Limited seed quantities in 2009. Bred and marketed by Pioneer Hi-Bred.
Hyola 571CL (tested as K9209). Early-mid maturing hybrid that flowered about 4 days earlier than 45Y77. Pacific Seeds indicate excellent early vigour, with good oil and yield potential. Blackleg resistance R (provisional).
Tested in NVT trials in 2008. Bred and marketed by Pacific Seeds.
SaharaCL (tested as J05Z-08960). Early maturing juncea canola, earlier than Oasis CL. Pacific Seeds indicate exceptional vigour. Blackleg resistance R (provisional). An End Point Royalty (EPR) applies. Tested in NVT trials in 2008. Bred by DPI Victoria and Viterra (Canada). Marketed by Pacific Seeds.
