This project aims to develop the next generation of elite industrial hemp cultivars, grown for their seed with high protein and oil contents, that are drought resistant and make minimal THC, teamed with research into their feminisation to provide a safer and better method of producing premium female seed to supply to growers. Project outcomes will include increased fundamental knowledge of drought tolerance, cannabinoid biosynthesis and the feminisation process, converted to practical ways to manipulate these important agronomic traits. This will derisk the industrial hemp industry, encouraging increased cultivation of a nutritionally and economically valuable crop in Australia and create valuable intellectual property applicable globally.Read moreRead less
Influence of high temperature on phenology, metabolism and the fate of axillary buds and inflorescences in grapevine. Subtropical regions in Australia, due to a warm climate, land and water availability, have the potential to produce a variety of agricultural produce, particularly fruit, to meet market demand. However adoption of fruit crops, many of which, including table grape, have temperate origins, requires intensive management.

Subtropical regions in Australia, due to a warm climate, land and water availability, have the potential to produce a variety of agricultural produce, particularly fruit, to meet market demand. However adoption of fruit crops, many of which, including table grape, have temperate origins, requires intensive management. Despite years of agronomic R&D, production remains variable due to a lack of fundamental knowledge on how climate impacts on the development cycle, particularly flowering, required to produce fruit. This proposal will carry out basic research to provide knowledge that will enable consistent production and expansion of table grape and other temperate crop industries.Read moreRead less

This project addresses the single biggest issue affecting the viability of pineapple farming in Australia and internationally: premature flowering leading to supply collapse. We aim to develop CRISPR technology to breed new pineapple varieties using non-GM approaches. Expected outcomes include the production of pineapples with resistance to premature flowering, as well as the technologies to deliver additional improvements in the future. The new varieties will benefit farmers through increased production, maximising supply capability for a rapidly growing internal demand. This will benefit Australian pineapple producers through higher profitability in existing markets, as well as enabling expansion into international and future markets.Read moreRead less
Understanding, controlling and improving the flavour of almond kernels. Almond kernels may be sweet, semi-bitter or bitter, with the first two categories marketed as fresh nuts, while the latter are used in processed products such as marzipan. Semi-bitter kernels have a more interesting flavour than sweet kernels and we require tools to breed for this character. The bitter flavour is imparted by amygdalin via the cyanogenic pathway. This project will characterise the genetic control of sweet, ....Understanding, controlling and improving the flavour of almond kernels. Almond kernels may be sweet, semi-bitter or bitter, with the first two categories marketed as fresh nuts, while the latter are used in processed products such as marzipan. Semi-bitter kernels have a more interesting flavour than sweet kernels and we require tools to breed for this character. The bitter flavour is imparted by amygdalin via the cyanogenic pathway. This project will characterise the genetic control of sweet, semi-bitter and bitter flavour, amygdalin accumulation in developing kernels, and key enzymes in the cyanogenic pathway. Almond populations segregating for these traits will be used and the data will be integrated into the Australian almond meiotic map.Read moreRead less
The role of phytotoxins in ray blight disease of pyrethrum and significance of toxin tolerance to disease resistance. Ray blight disease, caused by Phoma ligulicola, is the greatest threat to the Australian pyrethrum industry causing $2.0M in annual losses. We aim to clarify the pathology of P.ligulicola in pyrethrum, focussing on the role of fungal toxins during infection. Toxin importance in disease will be determined through histology and induction of toxin- pathogen mutants. Toxins will be ....The role of phytotoxins in ray blight disease of pyrethrum and significance of toxin tolerance to disease resistance. Ray blight disease, caused by Phoma ligulicola, is the greatest threat to the Australian pyrethrum industry causing $2.0M in annual losses. We aim to clarify the pathology of P.ligulicola in pyrethrum, focussing on the role of fungal toxins during infection. Toxin importance in disease will be determined through histology and induction of toxin- pathogen mutants. Toxins will be characterised and used in tissue culture to select obtain toxin tolerant pyrethrum clones that will be evaluated for agronomic performance and disease resistance. Successful development of resistant clones will decrease production costs, minimise risk of fungicide resistance development and reduce environmental pollution.Read moreRead less
The impact of vineyard exposure to smoke on vine physiology and the composition of grapes and wine. Taint in grapes and wine as a consequence of vineyard exposure to smoke has resulted in a decline in product quality and significant financial losses for grape and wine producers throughout Australia. Given the close proximity of many Australian wine regions to areas of bush and forest and the predicted continuation of warm, dry climatic conditions, the incidences of vineyard smoke exposure is exp ....The impact of vineyard exposure to smoke on vine physiology and the composition of grapes and wine. Taint in grapes and wine as a consequence of vineyard exposure to smoke has resulted in a decline in product quality and significant financial losses for grape and wine producers throughout Australia. Given the close proximity of many Australian wine regions to areas of bush and forest and the predicted continuation of warm, dry climatic conditions, the incidences of vineyard smoke exposure is expected to increase in the future. The project aims to establish grape and wine production methods which can be employed by industry to counter the effects of smoke on grape and wine composition, and to minimise smoke taint in finished wine; with clear economic benefits for grape-growers and wine producers.

Biological control of grapevine scales. Wine grapes can be grown with a minimum of pesticide and fungicide applications in some regions, but biological control is still required to maintain populations of major pests. This project is concerned with grapevine and frosted scales, which are common pests of grapevines. The distribution and identity of different grapevine scales, and their main parasitoids, in the various grape growing regions of Australia will be determined by initial surveys. Exper ....Biological control of grapevine scales.

The tomato industry is currently shifting towards production in greenhouses, which allows climate control and improved pest management. A lack of pollinators is an obstacle to this move. This project will establish protocols for large-scale use of native blue-banded bees as pollinators in greenhouses, especially for tomatoes. Pollination by native bees increases fruit weight by 15%, comparable to the effects of bumblebees used overseas. Significant economic, environmental and health benefits are expected from this project. The outcome will satisfy an industry need and remove an environmental threat by finding indigenous substitutes for alien bumblebees.Read moreRead less
Cellular and molecular interactions of rhabdoviruses with their plant hosts and insect vectors. Viruses cause significant economic losses in agriculture, but little information is available on how plant-adapted rhabdoviruses multiply in both their plant hosts and insect vectors. This project on the localisation, transport and host defence properties of essential viral proteins will identify novel targets for improved disease control.
