WHEAT National Variety Trial
Key Messages
-
In 2020 the top-yielding released varieties in the Ballidu NVT were Sting, LRPB Havoc, Ninja, Scepter and Catapult (3.57 t/ha average for the top 5 varieties) with 0.15 t/ha difference between the first & the fifth variety.
-
Season 2021 in the region started with rainfall events in February and March which provided some subsoil moisture, well above average rainfall for July has not resulted in waterlogging and the trial is on track for good yields.
​
Aim
The aim of the National Variety Trials (NVT) is to generate independent information for growers and industry about newly released varieties of field crops to the current commercial varieties grown in the area.
​
Background
The NVT program has been designed to identify the highest yielding varieties, free from the constraints of nutrition and disease. As a result, the nutrition and crop protection packages applied to NVT trials are typically higher than may be applied by the average grower. Management is the same for all plots with no differences in timing for crop protection or nutrition
All trials have 3 replicates of each variety and all plots are sown (and subsequently harvested) on the same day. Timing of sowing is dependent upon the season but is typically done within an average district “best practice” window and located on a typical soil type for the area.

Varieties released in 2020
Ballista will be most closely compared with Scepter and newer variety Vixen. Compared with Scepter, Ballista offers consistently higher yields across a broad range of environments and growing conditions while carrying very similar disease resistance attributes.
Denison is a Mace/Corack cross. It is a slow to very slow maturity spring wheat, which is very uncommon, but it fits the sowing window of mid-April in most parts of WA.
Hammer CL Plus is AH quality and has two-gene tolerance to label rates of Intervix herbicide. It is closely related to Mace with similar maturity and adaptability. It is suitable for tight cereal rotations.
Sting is a high-yielding, quicker-maturing variety particularly suited to the low-medium rainfall environments of WA.
Valiant CL Plus is a high-yielding, Clearfield Plus, slow season AH wheat. It has a longer maturity than Cutlass, providing a varietal opportunity to maximise early sowing opportunities. Its best performance has been observed in longer growing seasons. Valiant CL Plus has good grain size, test weight and a moderate plant height, similar to Mace.
Comments
The trial was sown on the 18th of May into moisture and has had excellent germination and seasonal growth so far. Good nutrition levels have set the trial up to yield well.
