Protecting the Australian chickpea industry through knowledge of the current Ascochyta rabiei fungal population and risk to resistance breeding strategies. Australian chickpea is highly vulnerable to epidemics of Ascochyta blight, which may cause total crop failure.

Australian chickpea is highly vulnerable to epidemics of Ascochyta blight, which may cause total crop failure. This project will help to maintain Australia's position as a major global chickpea producer through maximising the life span of current resistance genes to A. rabiei. and determining the applicability of other potential resistance sources. The knowledge that will be generated regarding the pathogen's potential to overcome host resistance is imperative for developing future disease management strategies, especially since more aggressive isolates exist outside Australia. The project findings will feed directly into the National Australian Chickpea Breeding Program.Read moreRead less
Fast tracking pea weevil resistance into field pea cultivars through interspecific hybridisation. Field pea is a high value export product of Australia and increased adoption will lead to greater sustainability of agriculture, improved farm income and value adding opportunities (eg. food industry) in regional Australia. Novel breeding tools used within this project will accelerate the development of pea weevil resistant field peas that are less dependent on the application of pesticides than cur ....Fast tracking pea weevil resistance into field pea cultivars through interspecific hybridisation. Field pea is a high value export product of Australia and increased adoption will lead to greater sustainability of agriculture, improved farm income and value adding opportunities (eg. food industry) in regional Australia. Novel breeding tools used within this project will accelerate the development of pea weevil resistant field peas that are less dependent on the application of pesticides than current varieties. Their availability will encourage further uptake of field pea into Australian cropping systems, contributing to environmentally sustainable farming systems by improving soil nitrogen levels and reducing the environmental effect of pesticides.Read moreRead less
Genetic variation in narrow leafed lupin (NLL) accessions and breeding programs. The centre of origin of a crop plant is expected to have the greatest extant genetic variation of wild relatives. Development of modern cultivars may be accompanied by a severe genetic bottleneck, whereby subsequent breeding efforts are hampered by lack of significant genetic variation within domesticated breeding material. This proposal will research the extent to which the available genetic variation in wild acces ....Genetic variation in narrow leafed lupin (NLL) accessions and breeding programs. The centre of origin of a crop plant is expected to have the greatest extant genetic variation of wild relatives. Development of modern cultivars may be accompanied by a severe genetic bottleneck, whereby subsequent breeding efforts are hampered by lack of significant genetic variation within domesticated breeding material. This proposal will research the extent to which the available genetic variation in wild accessions of the recently developed crop Lupinus angustifolius has been utilised in breeding programs around the world. Results will be applied to broaden the gene pool and improve adaptation of new cultivars in the National Lupin Improvement Program.Read moreRead less
Characterisation and selection of phytocompound and physical seed quality characters of chickpea (Cicer arietinum). To develop and expand both value and volume of the Australian market share for chickpea. Retention and expansion of existing markets will occur through improved seed physical traits such as size, colour and processing efficiency, whilst creation of new markets will be achieved through enhancing novel traits such as the level of phytocompounds. In collaboration with Victoria's Dep ....Characterisation and selection of phytocompound and physical seed quality characters of chickpea (Cicer arietinum). To develop and expand both value and volume of the Australian market share for chickpea. Retention and expansion of existing markets will occur through improved seed physical traits such as size, colour and processing efficiency, whilst creation of new markets will be achieved through enhancing novel traits such as the level of phytocompounds. In collaboration with Victoria's Department of Primary Industry staff, genes governing chickpea quality traits will be characterised through applying novel combinations of selection and analytical methods. A multidsciplinary team of plant breeders, grains chemists and molecular biologists will advance chickpea breeding in Australia by applying cutting-edge technologies.Read moreRead less
Seed quality and disease resistance trait mapping in lentil (Lens culinaris ssp. culinaris). To protect and increase our world lentil market share, the mission of the Australian lentil breeders is to develop lentil varieties with superior seed qualities. Three highly desirable seed quality traits are; fatter and larger shape, better splitting efficiency and resistance to blemishing by ascochyta blight infection. To speed up the development of varieties with these traits, the genetic loci governi ....Seed quality and disease resistance trait mapping in lentil (Lens culinaris ssp. culinaris). To protect and increase our world lentil market share, the mission of the Australian lentil breeders is to develop lentil varieties with superior seed qualities. Three highly desirable seed quality traits are; fatter and larger shape, better splitting efficiency and resistance to blemishing by ascochyta blight infection. To speed up the development of varieties with these traits, the genetic loci governing them will be characterised and closely associated molecular markers identified. Markers will be validated for their use in marker-assisted breeding programs via back-crossing and field and glass house testing.Read moreRead less
Pyramiding ascochyta blight (A. rabiei) resistance in chickpea. Ascochyta blight (A. rabiei) is the most devastating disease that affects chickpea production in Australia. This project will produce enhanced chickpea breeding germplasm with sustainable resistance to ascochyta blight. This will be achieved through the enrichment of highly informative genome linkage maps and the development of molecular markers closely associated with novel resistance genes. Markers will be used to screen backcross ....Pyramiding ascochyta blight (A. rabiei) resistance in chickpea. Ascochyta blight (A. rabiei) is the most devastating disease that affects chickpea production in Australia. This project will produce enhanced chickpea breeding germplasm with sustainable resistance to ascochyta blight. This will be achieved through the enrichment of highly informative genome linkage maps and the development of molecular markers closely associated with novel resistance genes. Markers will be used to screen backcrossed populations for novel resistance in order to pyramid the genes involved. The most resistant lines, to all of the A. rabiei pathotypes, will be selected for use in future resistance breeding programs.Read moreRead less
