SARDI has released the following one page summaries (Western Australia and Eastern States) of the features and benefits of the AEXCO Oat Hay Varieties.

The following variety notes on AEXCO oat hay varieties have been extracted from the SARDI 2020 Crop Sowing Guide.


A new early-midseason hay oat with improved septoria resistance.

Koorabup (tested as 05096-32) is a new high yielding hay oat variety developed for WA with a similar height and similar or slightly later hay cutting time than Carrolup. Koorabup has the best septoria resistance of any current hay variety. Hay and grain yields are similar to Carrolup. Hay colour is excellent with improved digestibility compared to Carrolup. Koorabup has improved foliar disease resistance and grain quality compared to other current hay varieties and combines improved septoria resistance with good rust and bacterial blight resistances. Koorabup has better grain quality than Carrolup, low screenings and bright grain. Koorabup has better lodging and shattering resistance than Wintaroo and Brusher and is similar to Mulgara.

Forester (evaluated as SV97200-3) is a new variety that was released in 2012. Forester is a very late hay variety adapted to high rainfall and irrigated cropping regions. It is seven to 10 days later than Glider, three days later than Riel, two days later than Targa, and three weeks later than Wintaroo. Forester has excellent early vigour and is an improvement compared to Glider. It has excellent lodging and shattering resistance. Forester has an excellent foliar disease resistance spectrum. It is moderately susceptible to CCN. It has good hay colour, but like all late hay varieties may not resist hot dry winds as well as earlier varieties. Forester has excellent hay quality and is an improvement compared to Glider, Tammar, Targa, and Vasse, but similar to Riel. Seed of Forester will be available from the authorized AEXCO Seed Distributor AGF Seeds (phone Tim Brown 03 53456262) in 2013.


Tammar is a new late tall hay oat variety that will be available in reasonable seed quantities in 2013. It is four to seven days later than Tungoo to cut.

Tammar also has an excellent disease resistance profile. It is moderately resistant to stem and leaf rust, septoria, BYDV, and bacterial blight. Tammar is the first late variety available with resistance to CCN, tolerance to CCN, and moderate tolerance to SN. Tammar has improved hay quality compared to Kangaroo. It has high crude protein and hay digestibility with lower WSC than Mulgara and Brusher, but higher than Kangaroo.


Tungoo was released in 2012. It is a medium tall mid to late season hay variety similar in heading date to Kangaroo. Tungoo has excellent disease resistance. It combines resistance and moderate tolerance to CCN and SN. It is also resistant to leaf rust and is the only variety with resistance to red leather leaf disease. Tungoo is moderately resistant to BYDV, septoria, and bacterial blight and moderately susceptible to stem rust. Hay yield is similar but hay quality is slightly better than Kangaroo. it has grain quality similar to Kangaroo but grain size is smaller resulting in higher screenings. Tungoo has low hull lignin which improves feed grain quality.


Brusher is an early-mid season tall oat developed by SARDI and commercialized by AEXCO Pty Ltd in 2003. It is two to four days earlier to head than Wintaroo and this suits it well to low rainfall areas. Although Brusher has inferior hay yield when compared to Wintaroo it is recommended to replace this variety where improved resistance to stem and leaf rust or improved hay quality is desired. Grain yield and grain quality is similar to Wintaroo, Wallaroo and Kangaroo with higher grain protein. Brusher is moderately susceptible to stem rust, BYDV, septoria, red leather leaf and bacterial blight. It is resistant to leaf rust, resistant but moderately intolerant of cereal cyst nematode and intolerant of stem nematode. When there is a high CCN population in a paddock with favourable seasonal conditions, Brusher will have significantly lower hay yield than tolerant varieties. Brusher is moderately low in grain lignin. compared to Glider, Riel and Vasse.


Mulgara was released in 2009 and is a tall mid season hay oat similar in heading time and height to Wintaroo. Mulgara is an improvement compared to Wintaroo for resistance to stem rust and bacterial blight. It is also an improvement compared to Wintaroo for lodging, shattering resistance and early vigour. Hay yield is an improved compared to Brusher but slightly lower than Wintaroo. Hay quality is better than Wintaroo. Mulgara has excellent hay colour and resists brown leaf tipping. Grain yield is similar to Wintaroo, but Mulgara has slightly better grain quality with the exception of high hull lignin.


Wintaroo was released in 2003. It remains a very popular mid season hay variety continuing to deliver excellent hay yield and quality across the major hay producing regions of Australia.
