Minimising the impact of major barley foliar pathogens on yield and profit: Development of international pathogen / host diversity sets (2021 - 2023)$37,000
Description
This is a nationally collaborated project. UTAS will be responsible for screening the selected diversity sets for scald and SFNB resistance. UTAS trial will be at Mt Pleasant Lab, Launceston, Tasmania. The trial will be sown in both Autumn and winter to ensure the success from at least one trial. Stubbles (with scald) from the previous years screening trials will be used to inoculate the trial.

Minimising the impact of major barley foliar pathogens on yield and profit: Screening of elite breeder material transitioning to a fee for service model (2020 - 2022)$37,000
Description
This is a nationally collaborated project. UTAS will screen a minimum of 200 barley breeding lines from Australian breeding companies for scald and SFNB at Mt Pleasant Lab, Launceston, Tasmania. This site is specifically set up for different stress tolerance, including BYDV, scad, SBNF and powdery mildew. Autumn sowing trials in this site showed very severe scald and SFNB while spring sowing is better for BYDV and powdery mildew. For this project, we will sow trials in both autumn and winter to ensure the success from at least one trial. Stubbles (with scald) from the previous years screening trials will be used to inoculate the trial.

Introgressing waterlogging tolerance gene to commercial barley varieties (2019 - 2023)$1,172,501
Description
Waterlogging has become one of the major abiotic stresses that limit the production of barley crop in high rainfall areas of Australia, in particular, Tasmania. The development of waterlogging tolerant varieties is an effective and economical approach to improve crop production under waterlogging conditions. However, the progress of developing waterlogging tolerant barley varieties is slow due to the complexity of waterlogging conditions resulting from different water depth, soil type, duration of waterlogging, nutrient ions and temperature. Waterlogging tolerance is also a complex trait, controlled by many genes including some with small effects. Molecular markers have provided plant breeders with a method to improve selection accuracy and accelerate breeding programs.In our previous studies, we have identified a new gene controlling one of the major tolerance mechanisms, i.e. aerenchyma formation in roots under waterlogging conditions. The new gene from a wild barley accession not only produces a greater proportion of aerenchyma but makes a greater contribution to the overall waterlogging tolerance. We have already fine mapped the gene and some co-segregating markers have been identified. These markers are now ready to be used in selection programs. A new system has also been established to develop a new variety in a very short time (3 years). After the workshop organised with farmers and GRDC representatives, farmers and GRDC showed great interests in supporting this work in TIA. I would like to apply for funding to support a postdoc to conduct the backcrossing and selection program. The end product, new variety, will provide direct benefits to grain industry.

Understanding the amelioration processes of the subsoil application of amendments in the Southern Region (2017 - 2021)$4,950,000
Description
Subsoil manuring is an exciting new technology that could revolutionise grain yields in the HRZ of Australia and bring them more into line with the high yields obtained in most of Europe and NZ. Without this technology (coupled with drainage In some areas) it is unlikely that yields of crops on duplex soils will come close to consistently meeting dry land and irrigated target yield potential.This project is a collaboration with Victoria (DEDJTR, LaTrobe, UM), SA (SARDI, PIRSA, UnlSA), NSW (DPI) and a number of grower groups, in particular SFS. It aims to develop the knowledge and agronomic practices required to achieve reliable and significant crop responses and to reduce the large financial risk and other logistical constraints currently limiting the potential uptake of subsoil amendments by grain growers in South Australia, Victoria, southern NSW and Tasmania. This project ultimately tarsets the development of effective pathways to widespread adoption of subsoil improvlns technoloay among grain growers and will be dependent on the delivery of several key outputs.

Sense-T Stage 2: Sensor-smart irrigation (2015 - 2016)$509,799
Description
This project will consist of collating existing; spatial data, sensor technology, and irrigation software (developed by NCEA) to deliver a working irrigation management tool. A simple to use mobile App using real-time sensory data to assist growers to decide when and how much to irrigate different soils or crops, tailored to their irrigation control system and site characteristics. Part of the project will undertake a review and evaluation of the use of sensors; what functionality is needed; and how decision making occurs with end users. The growers have indicated there is a need for a review to inform them of the sensors to use in their individual businesses. They are also need information on the best location of sensors and the optimal number of sensors required to provide reliable information and management zones within an irrigation area. One of the key objectives of the spatial data component of the project will be to determine the appropriate scale of mapping to match management zones.

Increasing pulse plant pathology capacity via a project to clarify the interaction of waterlogging and ascochyta in lentils and faba beans (2014 - 2015)$11,088
Description
This research project examines waterlogging and acid tolerance in lentils and faba beans, which requires plant pathology capacity to tease apart the association of disease as a response to waterlogging. The project will be a pot-trial in Mt Pleasant and involve stress-screening and pathogen Identification. The aims are to: 1) clarify the role of disease in screening for waterlogging and acid tolerance; 2) increase capacity in pulse pathology in Tasmania.

Effective control of barley yellow dwarf virus (BYDV) in wheat (2014 - 2019)$1,537,323
Description
For two consecutive years (2011 and 2012) YDV (BYDV) has been one of the major production issues in high rainfall areas of the southern region including Tasmania, Victoria and Western Australia. BYDV-PAV, vectored mainly by the aphid Rhopalosiphum padi, is the most prevalent YDV species in wheat and grasslands across all states, except Queensland. The virus is not seed-borne and persists from one growing season to the next in over-summering grasses. Early application of aphicides as a seed treatment has been recommended and used but has given inconsistent protection, so resistance/tolerance is seen as the best solution.
