Starfire

Starfire

• A consistently high yielding winter feed wheat
• High yield potential under early sowing and irrigation
• Well suited to Canterbury and Southland regions
• Wide planting window due to low vernalisation requirement

Description

STARFIRE is an established consistently performing feed wheat cultivar bred by Limagrain UK and further developed by PGG Wrightson Grain (PGW Grain). It has a compact efficient plant type with stiff short-medium straw. STARFIRE produces a plump soft endosperm grain with excellent grain quality characteristics.

Yield

STARFIRE has been a consistent performer in FAR CPT trials since 2012 across a range of sites throughout Canterbury and Southland. Although it is no longer topping as many trials as it was four years ago it remains a cultivar that will deliver top yields given appropriate management i.e. good, even plant establishment and disease control with appropriate fungicides. It has also been the overall highest yielding second wheat in FAR trials and again given good establishment and foliar disease management should be the first choice in this situation.

Time of drilling

The full yield potential of STARFIRE is most likely to be achieved from an early drilling window of early to late April. It will also produce good yields from May and June plantings due to its low vernalisation requirement and plant growth characteristics.

STARFIRE is an intermediate maturing cultivar. It is notable for its rapid development and grain fill after ear emergence.

Seed rate and tillering characteristics

STARFIRE has moderate tillering capacity and a tight V-shaped tillering habit. Target plant populations should be at the higher end of the ranges. A good guideline is to increase your sowing rate by 25% above the standard PGW Grain wheat seed rate guidelines.

Soil type, rotation and geography

STARFIRE has shown that it can perform well under a range of different soil types and environments in Canterbury, Southland and the lower North Island. STARFIRE has yielded extremely well under irrigation as well as many rainfed/dryland situations. It has also been the top yielding cultivar in the FAR second-year wheat trials since 2013.

Disease resistance

STARFIRE has good resistance to stripe rust but is moderately susceptible to most other foliar diseases, especially Septoria leaf blotch and one powdery mildew race. Considering this disease profile, a robust fungicide programme is recommended. Please contact your local PGW Representative for site specific recommendations.

Stripe rust 8 Moderately resistant
Leaf rust 5 Moderately susceptible
Septoria leaf blotch 6 Intermediate resistance
Powdery mildew 5 Moderately resistant
Fusarium head blight 5 Moderately resistant

Straw strength and height

STARFIRE is a medium height cultivar with good standing power. It responds well to moderate plant growth regulator (PGR) programmes. Use of PGRs is generally recommended, with the actual programme determined by a combination of sowing date, seed rate, nitrogen use, crop thickness and yield potential. Please contact your local PGW Representative for site specific recommendations.
