Barley Purity Project

Project Outcome

Barley

This project will introduce new technology into the malting barley industry that will help verify variety purity standards into the future. This will help maintain the Australian grains industry reputation as a quality malting barley producer and ensuring grower's grain has credibility and acceptance in the market place.

Project Summary

In this project SEPWA will undertake preliminary barley variety purity testing as an indicative industry benchmark. This bench marking will cover grower's seed for sowing (farmer saved and bought), tissue samples from the field and harvested grain in the Esperance port zone. There will also be testing from other sources across WA.

This project will introduce to growers the concept of varietal ID testing for malting barley at production level. It is likely that some form of variety ID testing will become mandatory in the future and this project serves to accustom growers to the concept. Results of this project will be presented to industry and contribute to designing a national approach to varietal purity in malting barley.

Project Funders

The project is jointly funded by the Department of Agriculture and Food Western Australia (DAFWA) and the Grains Research and Development Corporation (GRDC), with support from the CBH Group.

Project Background

Malting barley varietal purity is vital to the malting industry for performance efficiency in the malting process. There are strict receival standards in place across Australia that dictate malting barley must be varietally pure and that it is to be stored in separate stacks on a variety-by-variety basis.

Barley

Over the past 4 harvest seasons CBH (on behalf of the primary WA barley marketer Grain Pool Pty Ltd) has taken grain samples at delivery as well as sampled stacks for purity. Similar work has been done by ABB in the Eastern states. Due to the harvest pressure and bottleneck in testing not all growers' samples were tested. Additionally, feedback from this testing process has not been provided in time for growers to take corrective action in relation to finding out they have a variety purity issue and rectifying it in time for the following season.

The reliability of current testing methodologies for varietal purity, as well as industry-wide application potential, is under question when considering sample throughput, reliability and repeatability.

Through this project SEPWA will be engaging grower's interest in the topic of malting barley variety purity as an overall grain quality characteristic. SEPWA sees this as important proactive step to engage growers at the production level rather than possible negative feedback from marketers in the future when growers will be forced into prescriptive action.

Testing at the farm level will also inevitably lead to integration into existing QA systems such as the Better Farm IQ program and this is a step toward a whole supply chain variety testing from barley breeder to brew house.
