lodging resistance

Catalogue: GRDC Updates
Take home message Lodging creates a major challenge for plant breeders because of the trade off between lodging resistance and grain yield potential... The stay-green trait can have a significant effect in reducing the occurrence of lodging... The importance of pathogens on lodging and any build-up that may occur under continuous sorghum cultivation is unclear and needs more research...

While irrigated production was the focus of the work, the results are relevant to dryland growers in high yielding environments, who have experienced lodging in the last 2-3 years... It is important to note that we used various commercial fungicides to control rust at each location: good disease control is imperative in achieving high yields in susceptible varieties... The soil test just prior to sowing showed 200 units of N to 90cm depth, and another test suggested that a further 200 units of N was available as deep N below 90cm, but it was difficult to know how variable this was across the four different sections...

Irrigated wheat with dramatically reduced lodging potential could soon become a reality for growers with new germplasm likely to be delivered to seed breeding companies within three years from the Better Irrigated Wheat Germplasm research project funded by the Grains Research and Development Corporation (GRDC)... CSIRO Research Director and Better Irrigated Wheat Germplasm project leader Dr Lynne McIntyre said the current research aimed to identify lodging resistant lines and transfer the lodging resistance into regionally-adapted elite germplasm... "Basically the project aims to deliver to Australian breeding companies traits and regionally-adapted germplasm with stable high harvestable yields of above 7t/ha and reduced lodging where less than 80% of the crop is at a greater than 70 degree angle from the horizontal," she said...

Although sorghum ergot outbreaks can occur at any time of the growing season, levels in the warmer months are usually low, and manageable.. Claviceps africana , the fungal pathogen which causes sorghum ergot, is now endemic in Australia... Pollen plays a vital role in the biology of sorghum ergot - sorghum flowers which have been pollinated are resistant to infection by the spores, so factors which reduce the availability (eg., rainfall which moves pollen from the air) or viability (eg., night temperatures <15 C before flowering) of pollen can predispose flowering sorghum heads to infection...
