Tender Details

Canola is Australia-s third most valuable crop and is also the most important break crop for Australian wheat production. It was first introduced into the high rainfall zones of Australia and has now expanded to the low and medium rainfall zones (Zhang et al 2016). The physiological framework for crop yield improvement in many crops is generally well established and has been used to direct R&D approaches to improve water-limited yield potential for some time; however, understanding and application varies between crops. In wheat for example, the key drivers are well understood and have been manipulated for yield improvement in different target production environments, whereas canola which is a younger crop in Australia in comparison, the key drivers for WLYP are not so well understood. One area of improvement of WLYP is the source to sink relationship in canola between the above ground biomass and seed yield. Biomass and harvest index (HI) are key drivers of grain yield in canola. Breeding and agronomic practices have increased biomass of Australian canola over the last decade, however, low efficiency of the plant to convert biomass into grain (low HI) has slowed the advances of grain yield and potential profitability. Research using limited varieties has shown that there is significant variability in the level of biomass at flowering and the level of yield which can be achieved, however further research is required to determine what traits are having the greatest impact...
