Wheat On Wheat Varieties

Wheat responds positively to a well-planned rotation with other crop species. Rotation is by far the best management tool farmers have to manage disease, pests, weeds and nutrition.

In most rotations, growers get to an unavoidable point where they have to follow a cereal with cereal. Wheat sown into wheat stubble significantly increases disease risk, with yellow leaf spot (YLS) being one of the more damaging of these diseases.

YLS is a fungus that is transferred from wheat stubble, where active spores infect the wheat plant and can result in significant yield losses. YLS is hard to control effectively with fungicides, so choosing varieties with a reasonable level of resistance is the most effective tool currently available to growers.

Here are a few options growers have when it comes to varieties most suited to a wheat on wheat scenario, with a minimum MR – MS resistance to YLS.

NEW! Catapult

  • A high yielding choice for April sowing (as an alternative to longer season spring types eg. Trojan & Cutlass.)
  • This variety combines favourable maturity with CCN resistance and yellow spot resistance
  • Provides a flexible sowing window and is a safer option for sowing dry when germination date in unknown
  • Mid to late maturing variety with a wide adaptation and a good physical grain package
  • AH classification in Southern and South Eastern Zones
  • Available for the 2020 growing season

  • AH classification in Southern Zone and Feed classification in South Eastern Zone
  • Outstanding shorter canopy for crop and stubble management
  • Good Stripe Rust (MR), Leaf Rust (RMR WA) and Yellow Spot (MRMS) resistance
  • Improved Powdery Mildew resistance (MS) over Mace to reduce disease build up in lower canopies

Arrow

  • AH in VIC/SA, High yield and stable yield performance similar to mace
  • Outstanding high production canopy with short, erect growth habit and good standing ability
  • Sound test weight, large grain size and low screenings
  • High and stable yield performance with similar yields to Mace

Cobra

  • AH, High yielding med season variety
  • Good standability with exceptional yield on irrigation
  • Cobra has a base level of APR and this may provide some protection in the warmer spring months
