Litmus

An early maturing, acid tolerant barley

Litmus is an early maturing barley variety which is ideally suited to shorter growing season environments with acid soils in Western Australia. Developed through the Syngenta-InterGrain collaboration, Litmus has good grain plumpness, superior to Buloke and Baudin, and moderate-to-high levels of pre-harvest sprouting tolerance.

STRENGTHS

Ideally suited to the sandy textured, high aluminum, acidic subsoils in the northern and central cereal belt of Western Australia.
Early maturing variety, slightly earlier to flowering than Hindmarsh
Excellent early vigour with a similar growth habit to Mundah
Good grain plumpness, superior to Buloke and Baudin
Good test weights, similar to Buloke
Moderate to high levels of pre-harvest sprouting tolerance
Litmus will be released as a feed barley

Litmus receival

Litmus has been identified as expressing blue aleurone. This trait results in the expression of a blue hue in the aleurone layer, which is located immediately below the husk of the grain. This can affect the brightness of the grain, making it potentially unsuitable for certain overseas markets that have a desired colour or brightness specification on imported grain.

Below is an excerpt from the CBH website, providing commitment to Litmus receival options:

“As a result of expanded interest from growers to continue trialing the Litmus barley variety, CBH will continue to receive Litmus into feed barley segregations for 2016-17 season by actively managing the level of blue kernels in stacks. A tolerance will be applied to the current 1% blue kernel receival standard when testing occurs at the sample shed and some flexibility will be provided on accepting loads above the prescribed 1% limit based on the quality profile of the stack. This flexibility will depend on seasonal and regional conditions and the impact these have on the expression of blue colouring. This option will be provided while the broader industry decides on how to deal with blue aleurone in barley varieties.”
