  • Genetic improvements through selection to abiotic and biotic stresses
  • Evolving rice varieties with emerging farming systems

Background

Dr Peter Snell has 13 years experience with the rice breeding program at the Yanco Agricultural Institute since his appointment in January 1998 and is responsible for the release of five commercial rice varieties.

He has implemented a wide range of new techniques including increasing the number of quantitative measures recorded throughout small-plot testing and increased accuracy in determining breeding value through the use of restricted maximum likelihood statistical methods to account for field-based spatial variation and lab-based temporal variation.

He has re-introduced backcrossing into the breeding program for germplasm enhancement and stress tolerance.

Peter is the lead researcher evaluating aerobic rice varieties for temperate and tropical production in Australia.
