Enhancing Grain Yield Potential and Quality of Lupin. Sustainability of wheat production in Western Australia depends on the continued use of legumes, specifically lupins, in farming systems. The low returns to growers for lupins has jeopardised these sustainable systems. This project aims to gather new information to develop novel genetic strategies to increase yield potential and modify seed composition in lupins, enhancing their commercial worth.
Exploiting the Arabidopsis genome sequence as a molecular 'toolbox' for Brassica improvement. Australia's position as a major exporter of canola (Brassica napus) is under threat from genetic improvements in yield and quality being made by our international competitors. We will identify genes from Arabidopsis (the 'tool-box') that will be used to increase the speed of selection of new canola varieties with improved oleic acid content, disease resistance, and agronomic traits such as early flower ....Exploiting the Arabidopsis genome sequence as a molecular 'toolbox' for Brassica improvement. Australia's position as a major exporter of canola (Brassica napus) is under threat from genetic improvements in yield and quality being made by our international competitors. We will identify genes from Arabidopsis (the 'tool-box') that will be used to increase the speed of selection of new canola varieties with improved oleic acid content, disease resistance, and agronomic traits such as early flowering and cold tolerance. Genome similarity between Arabidopsis and canola will be exploited to map specific genes from Arabidopsis directly into canola. Based on this knowledge, we will develop gene-specific molecular markers for rapid selection of Australian-adapted canola varieties.Read moreRead less
Expanding the gene pool of canola (Brassica napus) by introgressing valuable genes from related species. Canola is a high value export crop from Australia, and an important rotational crop which improves sustainability of agriculture through a disease and weed break for cereal crops. While breeders have improved quality, disease resistance and adaptation of canola to Australian conditions over the past 30 years, this has reduced genetic variation to dangerously low levels. Wide crossing with d ....Expanding the gene pool of canola (Brassica napus) by introgressing valuable genes from related species. Canola is a high value export crop from Australia, and an important rotational crop which improves sustainability of agriculture through a disease and weed break for cereal crops. While breeders have improved quality, disease resistance and adaptation of canola to Australian conditions over the past 30 years, this has reduced genetic variation to dangerously low levels. Wide crossing with drought tolerant Brassica carinata (Ethiopean mustard) will help to alleviate this problem. New uses of biotechnology, combined with molecular genetics, will help to overcome species barriers to introduce useful new genes into canola for Australian canola breeders.Read moreRead less
Accelerating the genetic improvement of grain legumes for Australia by developing doubled haploid technology for field pea and chickpea. Doubled haploid technology is used in many broad acre crop species to accelerate cultivar development and create homozygous populations for genetic mapping. Field pea and chickpea have been unresponsive to this technique but a recent breakthrough by UWA researchers has resulted in haploid pro-embryos from in vitro cultured immature pollen. A barrier to further ....Accelerating the genetic improvement of grain legumes for Australia by developing doubled haploid technology for field pea and chickpea. Doubled haploid technology is used in many broad acre crop species to accelerate cultivar development and create homozygous populations for genetic mapping. Field pea and chickpea have been unresponsive to this technique but a recent breakthrough by UWA researchers has resulted in haploid pro-embryos from in vitro cultured immature pollen. A barrier to further embryo maturation has been identified, which we propose to overcome using powerful microscopy tools to elucidate haploid embryology processes. This information will be applied to develop world-first in vitro doubled haploid protocols for these species, which will facilitate the development and accelerated delivery to industry of better adapted, high yielding cultivars.Read moreRead less
