IntroductionGeorgia TrainorThe 2019 Wheat variety sowing guide forWestern Australia provides information to supportgrowers with decisions on variety selectionand management. This publication contains asummary on the yield performance of varietiesin the NVT, disease resistance ratings, a newsection on winter wheat varieties and agronomicinformation. Quick reference fact sheets for 22commonly grown and recently released varietiesare also available at the back of the guide,along with grain marketing information and seeddistributor information.When deciding whether to implement a newvariety into your farming system, it is importantto determine whether the change will provide anadvantage. A new variety should: have better or equal yield, grain quality and/or disease traitsprovide diversity or risk mitigationsuit current market requirements.Reviewing available trial information (NVT orDPIRD trials) is recommended. This bulletinprovides available information on disease,agronomy, yield and quality characteristics toassist you with variety choice and management.What to look out for now – newreleasesGeorgia TrainorThere have been a number of newly released linesin 2018.Devil is a short-mid season, Australian Hard(AH) wheat variety from InterGrain. Devil wasincluded in the national variety trials for the firsttime in 2017. Its yields in 2017 were very similarto Scepter (within 1-3 percent) across all Agzones(Tables 2 to 10). Devil is moderately resistant tostripe rust, moderately resistant to moderatelysusceptible to the older leaf rust pathotype butsusceptible to very susceptible to the latest leafrust pathotype.Illabo is a dual purpose winter wheat for grazingand grain production from AGT. Its maturity is3 days quicker than EGA Wedgetail. Until thisvariety’s quality is classified for WA it will bedelivered as a feed wheat. lllabo is moderatelyresistant to stripe rust, moderately resistant topowdery mildew and resistant to flag smut.Kinsei is a mid-long season variety, released byIntergrain, with the classification of AustralianStandard Noodle (ANW). InterGrain recommendKinsei to noodle growers in the southern areasof the state who are looking for a variety that islonger to mature than Zen and for growers lookingfor a variety of different maturity to spread frostrisk. Kinsei was included in the NVT for the firsttime in 2017, where it yielded slightly less thanNinja (except in Agzone 1), but out-yielded bothZen and Calingiri.Razor CL Plus is an Australian Standard White(ASW) Clearfield variety released by AGT in early2018. This variety provides an imidazolinoneweed control option for growers in problempaddocks that generally produce low proteincrops. Information from the breeder suggests thatRazor CL Plus yields higher than Grenade CL Plus(another AGT Clearfield variety with APW grading).In its first year in the NVT, Razor CL Plus had asimilar yield to Mace and Chief CL Plus.Another two varieties released in 2018 byInterGrain are Sheriff CL Plus and Vixen. Atthe time of publication, Sheriff CL Plus is a feedvariety in WA and seed is not available for the2019 season. Vixen, a high yielding AH variety willbe available to WA growers for the 2020 season ifseed becomes available.For more information on these varieties, contactthe breeder (contact details at the end of thisdocument).4nvtonline.com.au agric.wa.gov.au

Variety classificationSource: Wheat Quality Australia (WQA).The following class changes will apply in 2018: Carnamah: AH to APWHalberd: APW to ASWSpear: APW to ASWTo allow varietal control for maintaining productquality for the premium Japanese Udon noodlemarket, the classification of APWN is now a newsegregation in 2018 for the following AH andAPW varieties: Chief CL Plus, Devil, EGA BonnieRock, Envoy, King Rock, LRPB Scout, Mace,Westonia and Wyalkatchem.What should I grow and when?Dion Nicol and Georgia TrainorSince its release in 2008, Mace has becomedominant in wheat plantings across Australia.The adoption of this variety was at theexpense of older competing varieties such asWyalkatchem, Westonia and Carnamah thatwere replaced due to Mace’s better yields, AHclassification, stronger disease and sproutingtolerance. 2015 saw the introduction of Scepterwhich has similar agronomic characteristics toMace but has an average yield advantage ofaround 8 and 10 per cent. This increase in yieldis far greater than the yield advantage Mace hadover its key rival Wyalkatchem. In the comingyears, Scepter looks set to replace Mace asthe dominant variety and is already the secondmost planted wheat variety in Western Australia(Figure 1).With the superior yield performance of Scepterover three years of NVT, what else shouldbe grown and why? Diversifying into anothervariety should provide a measurable change inrisk or opportunity. It is important to consideryield performance in your environment and ifits maturity matches the targeted sowing time,the variety’s grain quality classification and itsvalue, disease risk profile and sprouting risk (FNI).Another essential annual activity is to reviewvariety’s disease ratings as these may havechanged due to new pathogens.To assist with the comparison of varieties,Tables 1-4 provide a snapshot of yields, diseaseratings, falling number index and relativematurity of varieties across yield groups, qualityclassifications and maturity. Notable varietiesare compared with Scepter and Mace toassist in variety selection. Preferred agronomiccharacteristics and disease traits will vary inpriority based on the pressure in the targetenvironment.Area sown 20162017YearFigure 1 Estimated area sown (% state plantings) of wheat varieties in Western Australia between 2012 and 2017.Source: CBH Groupnvtonline.com.au agric.wa.gov.au5

AH and APW short-mid season varietiesWhile a number of varieties released in the lastfive years can out-yield Mace, they are generallyinferior to Scepter in agronomic package and/or yield (Table 1). The yield advantage of Scepterhas been consistent in many environments anda wide range of yield potentials (Figure 2a). Thenewly released variety Devil is an AH short-midmaturity wheat released by InterGrain. While thereis only one year of data currently available on thisvariety, yield performance in the 2017 NVT wassimilar to Scepter.CL Plus wheatsWheat varieties denoted with ‘CL Plus’ identifiesthem as varieties with two resistance genes forImidazolinone herbicides and are registeredfor spraying with label rates of Intervix . Priorto the release of Chief CL Plus, Clearfield wheat varieties were significantly behind theelite varieties in yield. Chief CL Plus (APW) hascontinued to perform well, remaining competitivewith Mace in the NVT and far out-yields previousCL Plus varieties (Figure 2b). Chief CL Plus alsohas a good overall agronomic package withgood disease ratings (except for stripe rust)and a sound falling number index. Two newreleases, Razor CL Plus and Sheriff CL Plus, haveperformed similarly to Chief CL Plus in NVT yielddata to date. However, Razor CL Plus is ASWand Sheriff CL Plus will be delivered as a feedvariety until further quality information becomesavailable.Mid-long season varietiesMid-long maturity wheats are important for earlysowing or providing frost risk management.This is evident by the stability of the area sownto longer season varieties over the past fiveyears (Figure 1). Although most NVT are sownin May, which suits short-mid and mid maturingwheats, a number of mid-long maturities are stillcompetitive. For example, Cutlass, Magenta,LRPB Trojan are on average yielding similarlyto Mace.
