Wheat variety guide for Western Australia Supporting your success

Variety snapshots

Before adopting a variety it is important to consider why you want to replace existing varieties, and if the new varieties meet your needs.

The variety snapshots provide details on the strengths and weaknesses, End point Royalty (EPR), maturity and licensee details of the top ten varieties sown in WA in 2014, new varieties released in the last three years and varieties which have regionally specific adaption (Table 1). More detailed information on disease resistance ratings and agronomic traits are provided in Tables 3 and 4.

Yield using production value graphs

By assessing the production value of a variety over time and in locations relevant to your business (Figure 2), you get an indication of:

• 
  How much more a variety is likely to yield tonnes per hectare (t/ha) compared to other varieties in that environment.
  
• 
  The stability of the variety over a number of locations and years within an agzone or region.

NVT’s Yield Tool will display production values (also referred to as B.L.U.P. – best linear unbiased predictor) to compare the performance of varieties relevant to your business and location (visit nvtonline.com.au). More details on production values were presented at the 2015 Crop Updates (visit giwa.org.au/2015-crop-update).

We have continued to provide the average predicted yields for an agzone (2010–14) (Table 2). This information is an average based on the trials in each agzone over the 5 year period.
