Understanding a weed seed's potential for persistence - the timeframe weed seeds survive within the soil - is crucial to determining whether spraying or burial methods will be the most effective form of control... Department of Agriculture, Fisheries and Forestry (DAFF) principal research scientist Dr Michael Widderick says driving down the weed seed bank is growers' best defence against herbicide resistance issues and requires growers to deal with both the weed seeds already existing in the soil and stopping additional weed seeds from entering the soil...

Scientists share keys to drought tolerance Some of the world's leading crop researchers met in Adelaide recently to discuss breeding strategies for increasing plants' water-use efficiency By Gio Braidotti With global grain stocks at their lowest levels in decades and water stress accounting for a glaring proportion of global shortfalls, the 2007 Genomics Symposium in Adelaide allowed some of the world's best drought-tolerance pre-breeders to put their heads together on new ways to test, select and dissect traits that can maintain yields under drought... Overall, genomics is currently playing a more peripheral role in the work of conventional pre-breeders, with scientists attempting to dissect the genetic basis of drought tolerance and map traits to discrete chromosomal subregions (called QTLs or quantitative trait loci)... The number of GM field-trials is on the rise...

The paper describes an efficient, rapid method for screening against the two diseases for adult plant resistance under controlled environmental conditions... Inoculated plants were incubated in the dark for 48 h in a humidifier and disease assessed on a percentage scale, nine days after inoculation on the two lowest leaves that were fully emerged at inoculation... Seedlings were assessed on a 0-5 scale, seven days after inoculation while flag leaves were rated on a percentage scale, 14 days after inoculation...

The program of research developed around this position focuses on novel approaches to grain crop improvement in water-limited environments... It emphasises the design and testing of crop production systems that optimise combinations of genetic attributes (G) and agronomic management (M) in variable water-limited environments (E) using a systems analysis and modelling approach... The ways genes, environments and management systems interact to affect crop productivity has been captured in mathematical algorithms that turn computers into virtual paddocks, allowing simulated field trials to improve risk-management options and resource-use efficiency < Keep browsing..

Barley with genetically unique sources of adaptation to the low rainfall environments has been evaluated using lines from the International Centre for Agricultural Research in the Dry Areas (ICARDA)... Barley lines from ICARDA have shown potential for the improvement of adaptation, with adaptive features derived from wild barley and primitive barley landraces, and selection for yield and associated adaptive traits in drought prone environments with soils of low fertility... The germplasm and information gathered in this project will benefit industry since the project has had a focus on the improvement of adaptation as related to yield and physical grain quality...
