Eucalypt plantations in Australia have expanded rapidly over the last decade. With increasing market competition from overseas plantations for both pulp and solid wood products, Australia must maintain a competitive edge through efficiencies in production and product quality. Breeding and deployment of genetically superior planting stock is part of the solution. With global climate chance and requirements for re-afforestation in drier zones, there is an increasing requirement to genetically improve drought tolerance. This project will provide genetic information and strategies to back Eucalyptus globulus breeding and deployment programs for traditional as well as drier environments. Read moreRead less

Introgression of chromosome segments from related Brassica species provides an opportunity to develop locally adapted varieties with improved agronomic and quality traits. There is a need to understand Brassica genome organisation and how this information can be used for enhancing the efficiency of cultivar development. Dispersed and tandem repetitive DNA sequences provide valuable information on the organisation and evolution of plant chromosomes. Methods for monitoring chromosome segment transfer across Brassica species will be developed based on detecting and quantifying genome-specific repetitive DNA sequences. Australian Brassica improvement programs could benefit from this research by adopting methods to detect chromosome segment transfer during interspecific hybridisation.Read moreRead less

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

Australian forestry is shifting to high intensity eucalypt plantations and increasingly focussing on development of breeds and clones with superior wood and pulp traits. Many of these traits are under moderate to strong genetic control and DNA markers have helped identify regions on eucalypt chromosomes that influence these traits. This project aims to identify the genes at these chromosomal locations that influence wood fibre development and which have a strong influence on major commercial traits. The project will increase our understanding of wood and fibre development in eucalypts, and facilitate development of genetic markers to track superior genes during breeding.Read moreRead less
