Four lines showed good levels of broad spectrum resistance at various growth stages, environments and across all national sites and are important new sources of resistance that can be used by breeders for developing resistant varieties... Lines were assessed in the glasshouse at the seedling stage using four replicates sown as randomised blocks... Lines were assessed under controlled environment in duplicate using a partially replicated design...

The results of the survey indicate that spot-type net blotch occurs throughout barley growing areas of WA. Knowledge of genetic variation for virulence previously recorded for the pathogen has been significantly expanded, with a number of pathotypes not previously identified being now recognised... The work illustrates the existence of pathogenic variation for this disease in WA and has identified several new potential resistance donors... When the lines were evaluated at the Mt Ridley field trial, only a few lines (six - being Birka, Golf, Hannchen, Keel, TR251 and TR250) possessed adequate levels of resistance at the adult plant stage...

The aim of the project was to add value to the Agricultural Production Systems sIMulator (APSIM) tool by improving the underpinning science on which it is based... The ultimate impact of improving APSIM simulation accuracy is greater confidence in the outputs generated by APSIM... Of the eight wheat varieties assessed as part of this project, five of them have been adjusted in response to the phenology trial...

Yield Prophet , using APSIM modelling, simulates soil water, crop water use and N use on a daily basis and provides a risk assessment, through probability, of achieving a target yield.. (i) to compare soil water information provided by soil moisture probes vs. modelled outcomes from APSIM (Yield Prophet ) (ii) to evaluate soil moisture probes vs. modelled outcomes for day to day paddock management decisions.. Soil moisture probes do not provide information on soil/crop N status, and some kind of N budget is still required when deciding on whether the crop needs additional N in relation to how much water the crop has available to it...

In Figure 5, we show soil water measured at various depths using gravimetric methods and EnviroSCAN@" probes at Norwin in Queensland during 2010 - 2012 (Dalgliesh 2013)... The techniques also arise out of the aerospace industries, where the earliest approaches were developed for reducing errors in predictions of missile or spacecraft positions estimated from measurements of speed and direction... The really good news is that methods used in assimilating models and soil moisture probes could be used to improve the quality of the information from the model, and also the quality of information from the probes...
