Grain quality
Durack grain quality is excellent. It has an improved hectolitre weight and lower screenings compared to current milling varieties. Screening levels are a major improvement over Kojonup and Williams. Groat percent, and indication of processed yield after milling, is an improvement over Bannister and Williams.
| Variety | Hectolitre weight (kg/hl) | Grain weight (g) | Screenings (%<2mm) | Protein (%) (NIR)* | Oil (%) (NIR) | Groat (%) (NIR) | Beta-glucan ** (%) | Hull lignin |
|---|---|---|---|---|---|---|---|---|
| Bannister | 49.0 | 32.9 | 10.9 | 10.6 | 7.5 | 70.8 | 4.3 | high |
| Carrolup (tall) | 50 | 33.4 | 16.2 | 12.0 | 6.1 | 72.7 | 4.2 | high |
| Durack (tall) | 51.4 | 35.4 | 9.3 | 12.3 | 7.0 | 72.6 | 4.1 | high |
| Kojonup | 47.3 | 33.4 | 12.3 | 12.0 | 6.1 | 74.5 | 4.4 | high |
| Mitika | 49.1 | 35.3 | 9.0 | 12.2 | 6.9 | 72.7 | 4.4 | low |
| Williams (tall) | 48.0 | 31.7 | 15.1 | 10.6 | 7.3 | 69.4 | 5.2 | high |
| Yallara (tall) | 49.5 | 33.3 | 9.2 | 10.7 | 5.2 | 75.2 | 4.2 | high |
*NIR refers to near infra-red spectrometry assessment
** Beta-glucan data was collected from 2012-2014
Disease resistance
Durack is resistant to cereal cyst nematode and to predominant strains of leaf rust in WA. It is susceptible to stem rust.
| Variety | Stem rust | Leaf rust | Yellow dwarf virus | Septoria avenae blotch | Bacterial blight | Cereal cyst nematode |
|---|---|---|---|---|---|---|
| Bannister | MR-S | R | MS | S | MR-S | R |
| Carrolup (tall) | MS | VS | S | S-VS | MS | S |
| Durack (tall) | S | R-S | MS-S | S | MR-S | R |
| Kojonup | S | VS | MS | S | VS | S |
| Mitika | MR-S | R | S | S | MR | S |
| Williams (tall) | MR-S | R | MS | MS | MR | S |
| Yallara (tall) | MR-S | R | MS | S | MR | R |
R = resistant, MR = moderately resistant, MS = moderately susceptible, S = susceptible, VS = very susceptible, MT = moderately tolerant, MI = moderately intolerant and I = intolerant.
Seed availability
Durack seed is available through Heritage Seeds.
Durack has been bred to satisfy milling requirements. It will undergo final commercial milling evaluation after harvest 2016 to confirm its status before sowing in 2017.
The National Oat Breeding Program
The National Oat Breeding Program is a partnership between:
- Department of Agriculture and Food, Western Australia (DAFWA)
- South Australian Research and Development Institute (SARDI)
- Grains Research and Development Corporation (GRDC)
- Rural Industries Research and Development Corporation (RIRDC)
Its mission is to release improved oat varieties for grain or hay production, adapted to Western Australia, South Australia, Victoria and southern New South Wales.
