LMA Project B – A novel high-throughput, low-cost test to determine cause of starch damage in wheat grain
Show close time for other time zones
Falling number (FN) is a global industry standard used to quantify detrimental pre-harvest sprouting (PHS) in wheat, as early release from seed dormancy leads to significant effects on end product quality. However, a low Falling Number can also be caused by the trait of Late Maturity alpha-Amylase (LMA), with some wheats having a genetic predisposition to accumulate low levels of starch digesting enzymes during grain filling in the absence of sprouting. LMA susceptibility is currently a classification criterion for milling wheat in Australia.
This investment is one of three interrelated investments aimed at managing and eliminating the effect of Late Maturity alpha-Amylase (LMA) in wheat through improved phenotyping and modelling: PROC- 9176016 LMA Project A – Improved phenotyping for Late Maturity alpha-Amylase (LMA) susceptibility in wheat PROC- 9176017 LMA Project B – A novel high-throughput, low-cost test to determine cause of starch damage in wheat grain; and LMA Project C – An improved model of Late Maturity alpha-Amylase (LMA) field risk in Australian wheat.
This tender is for the development of a rapid, mobile, low-cost test for starch degradation in wheat grains which can also determine the cause of damage as LMA or PHS. Such a test will be valuable to breeders and pre-breeders seeking to determine the cause of starch damage in breeding material and research populations in the field, increasing the speed at which LMA susceptibility can be controlled by genetics. The technology could also be used by growers to aid post-harvest decision making and by grain receivers to rapidly and reliably determine starch damage.
It is expected that the successful applicant will propose an innovative approach that may include imaging science, biochemistry and/or molecular biology. The proposed approach may also borrow from other disciplines such as medical sciences, food sciences, physics and engineering. A proof of concept of the proposed approach will be highly regarded in assessment. The tender is open to private, public and private-public partnerships.
By 2030, Late Maturity alpha-Amylase (LMA) risk is managed within the Australian wheat industry as to maximise genetic gains and minimise downgrades to improve enduring profitability for Australian growers.
By 2023, Australian industry will have access to accurate, high-throughput screening tools for LMA expression that are employable early in breeding programs, research programs and applicable to a more cost effective, higher throughput LMA classification screen; growers will have the ability to determine starch damage of grain on-farm; and the industry as a whole will have access to accurate field risk profiles of LMA to inform decision making.
This will be achieved through the three interrelated investments.
By 2023, test developed to quantify starch damage and determine the cause as LMA and/or PHS.
The investment will be contracted on a GRDC Standard Research Agreement (Two Party).
