ABB Grain Presents Fleet a High Yield Grain in Collaboration with University of Adelaide and GRDC

Supplier News

Fleet Performance: ABB Grain Presents a new feed barley developed for Southern Australia by the University of Adelaide in partnership with the Grains Research and Development Corporation.

Fleet is a new feed barley developed as a replacement for Barque and Mundah. Fleet combines the plant architecture and phenology of Barque, the disease resistance and yield potential of Keel, and the adaptation to deep sandy soils of Mundah. Fleet exhibits an outstanding disease resistance profile, excellent physical grain quality, and a 5% yield advantage over the current dominant feed variety Barque.

Grain Yield

Fleet has maintained a consistent 5% yield advantage over Barque and a 13% advantage over Schooner in four years of field evaluation. The relative yield advantage over current varieties is evident across the spectrum of regions and soil types.

Significantly, Fleet exhibits excellent grain yield on sandy soils. Sandy soils are typically associated with dune/swale environments and characterised by poor fertility, rapid drainage of soil water, water repellency, leaching loss of nutrients, erosion, and a high incidence of root borne diseases. Barley occupies a key role in cereal production on these soil types, and Mundah has typically been the variety of choice due to its specific adaptation to sandy soils despite serious disease deficiencies. Fleet offers improved yield potential and yield stability on this challenging soil type in addition to broad adaptation.

Agronomic Profile

Fleet combines the plant architecture and phenology of Barque, the disease resistance and yield potential of Keel, and the adaptation to deep sandy soils of Mundah. Early vigour and weed competitiveness, flowering time and plant height of Fleet are similar to Barque, however it has an erect early growth habit similar to Mundah. WI3804 exhibits moderate to short basic vegetative phase and is photoperiod sensitive, responding positively to later sowing dates.

The physical grain quality of Fleet is characterised by very high grain weight, while screenings and test weight are similar to Barque and Keel.

Disease Resistance Profile

Fleet has a spectrum of disease resistance essentially equivalent to Keel, with the additional benefit of a significantly lower disease reaction to leaf rust. The breakdown of the scald and net form net blotch resistance in Barque are significant issues, and are likely to limit the longevity of this successful variety.
