1 Wheat variety sowing guide 2013 By Rob Wheeler, Senior Scientist, New Variety Agronomy Group, SARDI This sowing guide provides data and guidance on hard, soft and durum wheat varieties for sowing in South Australia in Since publication of the 2012 sowing guide, six varieties, namely Wallup, Grenade CL Plus, Longreach Cobra, Longreach Phantom, Shield and Emu Rock have been commercialised and may have some application in SA. In previous years these may not have been listed, pending evaluation over many seasons, but since they have disease resistances, yield and quality combinations important for the sustainability of SA wheat production, it has been decided they should be listed with comments to assist decision making. As with all new varieties, extensive state-wide evaluation within SARDI and National Variety Trials (NVT) over many seasons will provide more confidence in their suitability and any specific adaptational requirements. Further yield evaluation is needed for Grenade CL Plus, Cobra, and Shield, as each have currently only been evaluated for one year (2011) within NVT and no yield data is included within this guide. Meanwhile further data from 2011 NVT has been gathered to support the imidazolinone tolerant varieties Kord CL Plus and Justica CL Plus as suitable to be grown in SA, and hence yield and other data for them is now included within this sowing guide. The older varieties, Clearfield JNZ and Frame, have been removed from the 2013 sowing guide owing to low production and outclassed agronomic characteristics when compared with more recently released varieties. Growers should note that a number of newer varieties listed in this guide are below acceptable industry standards for rust resistance but offer other important or useful attributes. If grown, these varieties should be accompanied by suitable rust preventative strategies. Where varieties do not meet minimum disease resistance standards for rust, as set by industry, they are listed with a cautioning note. Varieties have been listed according to maximum market receival quality classification and are listed in alphabetical order and not in order of preference or recommendation. (See table on the next page). Selection criteria Information on the most important selection criteria, grain yield, quality, maturity and disease resistance for each variety can be found in tables 1 and 2. While the varieties listed below are considered likely to provide the best return within each quality grade, farmers need to consider their individual farm and paddock situation and make their selection based on all available information. Where possible, the growing of a single variety only should be avoided. Climatic, disease and price risks should be spread by growing at least two or more varieties with varying maturity, disease resistance and/or quality classification. Average protein content for current wheat varieties is very similar and rarely varies by more than one percent when grown under identical conditions. Perceived differences in protein achieving capability between varieties should be given only minor emphasis and protein should be managed through good crop nutrition. Notes on newer varieties Rob Wheeler AGT Katana A. Katana (RAC1423) is an early flowering, premium quality variety released for specific export markets. Derived from Kukri, Katana has good physical grain quality, similar to Yitpi, and yields similar to Wyalkatchem on average. Katana has modest rust resistance and is moderately susceptible to CCN but rated MR/MS to yellow leaf spot and powdery mildew. CBH Grain may contract Katana for export with possible premiums above AH1 passed to growers. Seed is available through AGT (Seed Sharing between farmers is allowed with Axe A. Axe (RAC1192) is a vigorous growing, very early flowering, AH quality variety. With large grain and low screenings losses, it has shown high yield potential in SA under very dry and sharp finishing conditions albeit with more moderate yields under favourable spring conditions and is susceptible to sprouting. Axe has good resistance to all rusts but is susceptible to CCN and yellow leaf spot and S-VS to septoria tritici blotch. Seed is available through AGT (Seed sharing between farmers is allowed with Bolac A. Bolac (VQ2621) is a long season, milling wheat, eligible for AH and released by AGT. It is suitable for mildly acidic to alkaline soils and could be an alternative to feed wheats and later varieties such as Chara, in the SE of South Australia. Bolac has good rust resistance, and is later flowering than Chara, but earlier than Kellalac. Seed is available through Viterra. Corack A. Corack (VW2316) is an early maturing APW (2013 harvest) quality wheat derived from Wyalkatchem. It has CCN resistance and good yellow leaf spot resistance but is moderately susceptible to leaf and stripe rust and very susceptible to powdery mildew. Trials, in SA NVT during 2010 and 2011 indicates a high yield potential, particularly in low to medium rainfall situations. Corack has only recently been released in Western Australia, with seed available through AGT (Seed sharing between farmers is allowed with Correll A.

The domestic flour millers purchase a small proportion of South Australian wheat either from marketers or directly from growers. The domestic flour millers can have different quality requirements to export markets due to different end products and processes employed. Table 3 lists the flour millers variety quality ratings, which provide growers with an indication of the most highly sought varieties. For further information, contact Laucke Flour Mills ( ).
