’High-vigour’ wheat puts weeds in the shade

16.06.2004



CSIRO is breeding new ’high-vigour’ wheats so fast-growing they can out-compete weeds while maintaining high yields.

Weeds cost Australian farmers over $4 billion annually in chemical and mechanical control and yield losses.

"High-vigour wheats have the potential to provide significant economic savings and environmental benefits for Australian agriculture," says Dr Greg Rebetzke, CSIRO Plant Industry.



"In field trials where wheat crops have to compete with weeds, the high-vigour wheat yielded double the grain of current varieties."

The new wheats shade the soil surface, suppressing weeds and saving water by reducing soil evaporation.

They also have more robust root systems than current varieties, enabling them to starve weeds and access water and nutrients deep in the soil.

The high-vigour conventional breeding program follows a three-year study by CSIRO and the University of Adelaide that evaluated the competitiveness of over 200 wheat lines from Australia and around the world.

The study found that competitiveness in Australian wheat has been largely bred out over the last 100 years, as breeders focused on better grain quality and disease resistance.

"We measured a range of traits including wheat and weed seed yield, rate of leaf area development and the ability to suppress or tolerate weeds, selecting the most vigorous wheat lines for further breeding," says Dr Gurjeet Gill of the University of Adelaide.

"The program is now breeding the high-vigour traits into commercial wheat varieties for release to growers. Varieties are expected to be available in four to five years."

Further CSIRO research is aimed at understanding genetic control of early vigour and developing breeding strategies to improve the efficiency of selection.

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
