Genetic analysis in barley suggests that the Rrs1 gene locus is a region that either hosts a suite of different scald resistance genes or numerous alleles of this gene exist in barley germplasm... Modern tools to identify desirable breeding traits are molecular markers that indicate the presence or absence of a gene that is responsible for the trait... Aligning the disease scores from each progeny line with its genetic fingerprint information revealed those fingerprint signals (molecular markers) that predict the resistance of a progeny plant most accurately...

Aerating grain in storage creates cool, uniform moisture conditions throughout the grain bulk... A simple device called an 'A-Flow' has been developed to measure the air-flow rate of an aeration system to check its performance... A simple calculation can then determine the volume of air (cubic metres or litres per second) the aeration fan is pushing into the grain storage...

Aeration uses fans and ducting to blow outside (ambient) air through grain... Running fans at the wrong time of the day or during unsuitable weather conditions can rapidly reheat or slowly rewet grain... During aeration drying, fans are designed to force much larger volumes of air through the grain bulk for much longer periods of time to ensure drying fronts are pushed quickly through...

GRDC Grains Research Update Coonabarabran, February 2014 most sites achieved those returns within 2 crop seasons after deep P application may at least partly reflect the string of wetter seasonal conditions in recent years, although the results from Jandowae, Capella and Gindie all included dry seasons in at least one of the crops followed... Overall, the performance of the barley grain only varieties showed they are capable of producing around 6 t/ha of dry matter and still yielding between 2.7 and 3.4 t/ha of grain... Overall, the most prevalent virus was BWYV and in some locations more than 90% of symptomatic plants were infected with BWYV (Table 1)...
