The guide provides characteristics, disease ratings and agronomic information for oat varieties that offer the best opportunity to meet market requirements (Tables 1–14 and Figures 1–11) .  \nMany oat grain varieties are available for delivery into the CBH Group system. Grain Industry of Western Australia (GIWA) oat delivery grades available at selected CBH receival bins are OAT1 and OAT2, while OWAN is an exclusive segregation for Wandering oats. All milling oat varieties, except Wandering, can be delivered as OAT1, provided they meet the required quality specifications. Each variety has its strengths and weaknesses across different growing regions. Most successful oat growers choose to grow more than one variety because no single oat variety is likely to provide optimum agronomic traits, disease resistance, yield and quality in any one year. Some milling oat varieties are suitable for baling as export hay, but hay-only varieties may provide a better option for dedicated export hay growers. This guide summarises the suitability of oat varieties for grain and hay (Table 1) . It also outlines the characteristics of 3 new oat varieties relative to 4 established oat varieties (Table 2) . The variety ‘snapshots’ at the end of this section summarise the strengths and weaknesses of all grain and hay varieties documented in this bulletin.  \nThe decision on whether to grow an OAT1, OAT2 or OWAN grain oat depends on 5 main factors:  \n1. The premium paid for different varieties based on their receival grade.  \n2. Relative grain yield of oat varieties.  \n3. Differences in input costs due to their agronomic and disease characteristics.  \n4. Likelihood of meeting oat receival specifications.  \n5. Location of receival segregations for OAT1 and OAT2 varieties.  \nOats  \n2026 Western Australian Crop Sowing Guide 151  \nOats  \nGrain oat variety choices in 2026 – what should I grow?  \nResponsibility for oat classification in WA has transitioned from GIWA (a regional classification) to Grains Australia (a national classification) . Following consultation with Grains Australia, CBH, and domestic oat processors, it has been confirmed that the existing segregation terminology—OAT1, OAT2, and OWAN—will remain in place. From the 2024–25 harvest, all varieties classified by Grains Australia as milling oats are eligible for delivery into the highest GIWA segregation, OAT1, provided they meet the required quality specifications. The newly accredited milling varieties Goldie (tested as 13008-18), Koala (09143-35), and Minnie (15010-09) are eligible for delivery as OAT1 . A further review of the WA classification systems has led to the acceptance of Durack into OAT1 stacks starting from the 2025–26 harvest. However, no changes were made for Wandering, which remains eligible only for OAT2 and OWAN delivery.  \n2024  \n\n| BANNISTER 60% | CARROLUP\u003Cbr>16% |  |  |  |  |\n| --- | --- | --- | --- | --- | --- |\n|  | YALLARA 9% |  |  | WILLIAMS 7% |  |\n|  | WANDERING\u003Cbr>2% | PALLINUP\u003Cbr>2% | OTHER\u003Cbr>1% |  | DURACK 1% |\n|  |  |  | BILBY\u003Cbr>1% |  | MITIKA\u003Cbr>1% |\n|  |  |  |  |  | KOWARI 0.3% |\n\nFigure 1: Relative popularity (percentage of oat area) of the top 10 oat varieties plus the combined area sown to the remaining 7 varieties delivered in WA in 2024 and 2025.
