DAN00023 - Viruses and vectors in the Northern Region: support for resistance breeding and information for integrated control
This project addressed virus diseases in broadleaf winter crops, mainly in northern New South Wales (NSW). Crops of concern were chickpeas, faba beans, field peas, albus lupins, and canola, and potentially forage legumes and alternative crops such as mustard.
Bean leafroll virus (BLRV) is a serious disease on of pulses. Improving resistance is the most economic and environmentally sustainable way to control this disease. This project aimed at identifying resistant pea germplasm and using this as parents in the breeding program.
DAQ00038 was designed to transition the Northern Barley Improvement Program (NBIP) away from malting barley and towards developing high yielding, disease-resistant feed varieties. Strategic changes occurred in order to accomplish this leading to major improvements in disease screening, quality assessment, and field trials.
The principal aim of this project was for the Northern Barley Improvement Program (NBIP) to develop the capability to efficiently use molecular marker technologies. During the two-year time frame of this project, the routine implementation of marker technology has increased significantly from eight populations targeted for two traits in 2003, resulting in approximately 60% of lines (150 lines) assayed being positively selected, to 19 populations targeted for seven traits in addition to marker-assisted recurrent parent recovery (MARPR) in 2004, resulting in approximately 55% of lines (1,551 lines) assayed being positively selected on the basis of the marker data.
The Weed Seed Wizard is a computer simulation tool that can predict weed emergence and crop losses across Australian grain growing regions using local paddock management information and weather data. This project developed a fast, user-friendly tool that can be easily used to simulate how various farm decisions can affect weed numbers and help with suitable weed management choice.
