VARIETY TECHNICAL GUIDE | DEVILA

VARIETY TECHNICAL GUIDE | DEVILA O1

DEVILA OVERVIEW DEVILA is a high yielding, quick-mid spring wheat with a similar maturity to MACEA and is distinctly earlier than SCEPTERA. The variety is broadly adapted and has performed exceptionally well within InterGrain trials over the last four seasons and NVT over the last three (2017 – 2019).

DEVILA offers an opportunity to spread risk across the wheat program.

DEVILA has an AH and AH(N) classification. DEVILA’s AH(N) classification offers an advantage in situations where pricing premiums and segregations are available. If AH is not achieved, growers can potentially deliver APWN and may receive a small potential premium compared to APW1.

DEVILA has an effective disease resistance package in Western Australia, in particular strong yellow spot resistance (MRMS) and very good stripe rust resistance (MR). The variety also has very good physical grain characteristics, with a good grain size, reducing screenings.

DEVILA’S GENETIC RELATIONSHIP The genetic relationship between commonly grown wheat varieties is represented below (Figure 2). DEVILA is most closely related to VIXENA, a high yielding AH variety, with an earlier maturity than DEVILA. DEVILA has a novel source of diversity packaged into a WYALKATCHEMA/MACEA


Figure 2. Common Australian wheat variety genetic relationships.

background. When interpreting the relationship dendrogram focus on the height at which any two varieties are joined together and if they are next to each other. For example, we can see that DEVILA and VIXENA are most similar as the height of the link joining them together is the smallest. ROCKSTARA and DEVILA are the next two most similar varieties. ROCKSTARA is a mid-slow spring AH variety also with a WYALKATCHEMA background.


DEVILA DISEASE INFORMATION

Commentary on DEVILA and its disease profile has been provided by research scientists in plant pathology at the Department of Primary Industries and Regional Development (DPIRD). The colour scale marked indicates the risk of occurrence in a typical WA season and the possible crop effects. These comments and ratings are a guide only. Growers, please speak with your agronomist or consultant for management decisions and options.

Powdery mildew

Risk rating (High): Powdery mildew epidemics develop rapidly, particularly in susceptible varieties, the fungus has a rapid lifecycle and produces masses of windborne spores on infected plants. It will require pro-active management in most environments when disease pressure is high and epidemics occur. Spores survive between seasons on volunteers, stubble and plant residue and disease risk is greatest in years with autumn green bridge. Research from DPIRD has shown that when powdery mildew is not controlled, yield loss can be > 20%.

Powdery Mildew - SVS


Yellow spot Risk rating (Low-moderate): A stubble borne disease which occurs commonly throughout wheat production areas causing necrotic leaf lesions and premature leaf death. Yield loss is less likely in MRMS varieties particularly in rotation with break crops. Fungus infection is much greater where moist conditions and leaf wetness extend over longer periods and are more frequent during the growing season; usually less severe impacts in drier regions. The risk of infection becomes greater if the crop is planted into wheat stubble, is a susceptible variety or if it is a higher rainfall season.

Yellow Spot – MRMS

Nodorum blotch Risk rating (Moderate): A common stubble borne disease where primary inoculum is from infected stubble. Can cause leaf necrosis and glume blotch. The risk of occurrence is greater in high rainfall zones as secondary infections can occur from splash dispersed spores during rainfall events. Greatest risk is associated with susceptible varieties and higher spring rainfall, less likely to be an issue in the low rainfall environments.

Nodorum Blotch - MS

Leaf rust Risk (High): Like all rusts, leaf rust is supported by an autumn green bridge. It has a rapid life cycle and produces masses of wind-borne spores that can spread rapidly over long distances. The disease can develop quickly and cause significant yield losses. Susceptible varieties require proactive management in leaf rust outbreaks. Epidemics are driven by a green bridge, mild weather and susceptible varieties.

DevilA will require proactive management for leaf rust.

Leaf Rust - SVS


Stem rust Risk (Low-moderate): The impact of this disease can be very severe, however recent outbreaks have been sporadic. Fungicide management is critical when stem rust is present as significant losses can occur in MS or lower rated varieties. Stem rust is favoured by warmer conditions, epidemics are usually later in the season and driven by a green bridge, spring rainfall and susceptible varieties.

Stem Rust - MS

Stripe rust Risk (Low): Stripe rust outbreaks are rare in WA, however when present, greatest response to fungicide management is seen in VS-MS varieties. Variety resistance is the most effective control measure and varieties that are rated MR and higher are less likely to require fungicide management. Stripe Rust - MR

The ideal emergence window for DEVILA is mid-end of May. The maturity difference between SCEPTERA and DEVILA will diminish when sown in June. DEVILA is earlier to flowering than SCEPTERA, providing an opportunity to spread risk during spring stress periods. The data in Figure 4 has been provided by the DPIRD Wheat Agronomy Project.


DEVILA’S TIME TO FLOWERING DEVILA is a quick-mid spring variety. DEVILA is generally earlier to flower than SCEPTERA and slightly earlier than MACEA. Thermal time accumulation is DEVILA’s strongest developmental driver. This is clearly shown by April sowing times in the graphs below, particularly in warmer environments. Planting before early May is therefore not recommended.

GRAIN QUALITY


Figure 5. Hectolitre weight and screenings percentage of DevilA, LRPB HavocA, MaceA and ScepterA.

DEVILA has good physical grain characteristics. It has a similar hectolitre weight to MACEA based on its performance in NVT trials over the past three years. Similarly, it has a large grain size, with a higher 1000 grain weight than MACEA, assisting in reduced screenings levels.
