CSIRO's Dr Richard Richards and Professor Graham Farquhar, from the Australian National University (ANU), have been awarded the UK-based Rank Prize for their development of methods that identify crops with superior water use efficiency (WUE)... The award relates to their discovery in the 1980s when they were able to correlate WUE in wheat crops to the ratio of carbon isotopes in the leaf... Today Dr Richards is a leading researcher at CSIRO Plant Industries, working on the continuing development of dual-purpose wheats for high-rainfall zones...

Dr Richards says longer season cereals that can be sown from February to June are most desirable for the HRZ because they make better use of the growing season and provide crop cover for a longer duration... "Longer season wheats are also more efficient users of fertiliser and have a greater water use efficiency compared with standard season wheats," he said... Dr Richards says germplasm coming from New Zealand or the northern hemisphere (via NZ) is going to be an important source of high yielding, disease-resistant HRZ germplasm for Australia...

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...

Pressure continues to mount on cereal pre-breeders to find ways to quickly increase the yield potential of staple crops - for global food security and for the viability of commercial growers.. Yield is back on the agenda - the need to get more grain from each cereal plant grown... Other studies of yield potential follow a similar pattern, including gains of: 0.3 per cent annually in irrigated spring wheat based on experiments in the Yaqui Valley in Mexico in 2005 (although the rate halves in Mexico's warmer Tlaltizap n and has shown little tendency to increase in cultivars released after 1966); and 0.68 and 0.75 per cent annually in irrigated winter wheats based on historic set studies from different periods in the main winter wheat regions in China...
