Understanding phenology and early pod set under high biomass conditions

Summary

Faba bean is an important grain legume in Australia. A breeding program to develop suitable varieties for the northern grain growing region of Australia is located at the University of Sydney’s Plant Breeding institute, Narrabri. Rust, chocolate spot and viral diseases, such as bean leaf roll virus and bean yellow mosaic virus are major biotic stresses while frost tolerance in early growing season and heat tolerance towards the grain filling period are major abiotic stresses in this region.

Synopsis

Early sowing in favourable moisture conditions can lead to faba bean biomass production as high as 14 tonnes/ha. However, not enough of this biomass is converted to grain production, resulting in a poor harvest index. Understanding the mechanism of partitioning of this biomass into grain yield and its exploitation can lead to greater yield improvement. Only 15-20% of flowers develop into pods and the rest are aborted. Low temperatures result in poor pod set, whereas temperatures above 30ºC result in flower and pod abortion. Therefore, the effect of temperature on flower and seed development needs to be understood to develop varieties with appropriate phenology in the target environment.

Additional Information

The student would undertake lab studies mainly at Cobbitty and field work at the Plant Breeding Institute, Narrabri.  Students will have greater interaction with scientific staff and students working at both locations.
