Albus or white lupin (Lupinus albus L.) is an annual legume traditionally cultivated around the Mediterranean and along the Nile valley where it is used for human consumption, green manuring and as forage. The composition of the grain and especially the high protein content makes white lupin highly suitable for ruminant diets as a protein-rich product in intensive farming systems including Australia. White lupins are susceptible to various fungal diseases including Pleiochaeta setosa which causes root rot and is a major threat to lupin crops in Australia. Two disease resistant varieties “Luxor” and “Rosetta” have been developed by the Department of Primary Industries (DPI), Wagga Wagga, NSW, Australia and are commercially available. Development of molecular biology techniques offers new prospects in white lupin breeding. Markers are already developed for anthracnose resistance in Albus and low alkaloid content. However, to date no work has been undertaken to understand the genetic basis of resistance to Pleiochaeta setosa in Albus lupins.
The main focus of this PhD is to develop molecular markers for Pleiochaeta setosa resistance genes to enable marker assisted selection in the breeding program.
