Oat
Season
Mild temperatures and good rainfall at the start of the season allowed oats to grow well for the first half of the season producing good quantities of biomass. Many growers took advantage of the high biomass to cut for hay rather than take a chance on grain production.
As observed with other crops, oats performed better in the east and to a certain extent the South West. Yields in the west compromised by dry conditions and some frost damage.
Disease
Dry conditions meant the incidence of rust and red leather leaf were low in 2014. Barley yellow dwarf virus was common in the high rainfall zone.
New varieties
Williams, a new milling variety with early maturity was released last season in WA and is available in the eastern states for the 2015 season. Williams and Bannister now set the benchmark for grain yield.
Disease
It is important that growers understand the resistance/susceptibility of their varieties to the diseases of importance in their region and plan management strategies accordingly. Managing the green bridge will be important after summer rain events.
Quality
Variety selection should be based upon agronomic traits, potential grain quality and marketing or end use options.
Oats are grown for human consumption or animal feed as a grain or hay. Grain quality traits for the milling industry include high groat percent, high β-glucan, low screenings, and high hectolitre weight. Grain quality traits for improved animal feed include low hull lignin, high groat percentage, and high oil content, resulting in high grain digestibility.
Important hay quality traits are high digestibility, high water soluble carbohydrates, low fibre and high protein.
The option of oats for hay is increasing in popularity where growers have identified it as profitable, as a tool to manage herbicide resistance and to spread risk. Variety performance for hay yield and quality is available in the Oat
Newsletter at www.sardi.sa.gov.au/crops/publications/newsletters.
Royalties
Where applicable, growers selling oat seed or export hay will pay an End Point Royalty (EPR). Growers producing domestic hay from PBR varieties will pay a seed royalty of
$2/tonne, but will not pay an EPR. The AEXCO oat EPR for export hay is $2/tonne (ex GST).

Milling Oat – WILLIAMS
A medium to tall milling oat suited to medium to high rainfall zones. It is 15cm taller than Mitika, 5cm taller than
Bannister and 15cm shorter than Yallara. A higher yielding variety, similar to Bannister but with slightly inferior grain quality. Produces high screenings when grown in low rainfall areas. S to stem rust, but R to leaf rust and S & I to
CCN. MRMS to septoria. Bred by the National Oat
Breeding Program (WA2332). Released in WA in 2013, it is available for eastern Australia for 2015. Marketed by
Heritage Seeds. EPR $2.30.
Milling Oat – WOMBAT
A dwarf mid season variety that flowers about six days later than Mitika. It is the first dwarf milling variety with CCN resistance and tolerance. Intended to replace Mitika and
Possum where CCN and stem nematode are limiting yield, but may have higher screenings. Bred by SARDI
(SV97181-12), released 2011 and marketed by Seednet.
EPR $2.
Milling oat
– YALLARA
Medium to tall similar to Euro, which it is intended to replace. S to stem rust and MS to leaf rust and septoria.
Resistant but intolerant to CCN. Suited to drier areas. Bred by SARDI, released in 2009 and marketed by Seednet.
EPR $2.

Mitika for milling quality. Moderately tolerant to stem nematode but susceptible to rusts and CCN.
Released 1984 by SARDI.
Feed oat – POTOROO
A widely adapted early feed grain semi-dwarf variety.
Suited to low rainfall areas where CCN is a problem.
