A prototype near infra-red (NIR) analyser that records grain protein and moisture during harvesting is giving promising in-field results.

Mounted on a small, trial plot header used by Queensland's Department of Primary Industries and Fisheries (QDPI&F), the analyser is being used to match experimental lines from the department's GRDC supported breeding programs with grain quality.

QDPI&F research scientist Glen Fox says being able to record grain protein and moisture "on the run" had enormous benefits for wheat breeding through efficiency gains and the faster evaluation of potential varieties.

Recent advances in computing, and miniaturisation in electronics had significantly reduced the size of NIR instruments, opening the way for mobile protein and moisture measurement.

Trials of the mobile NIR equipment on the small plot header showed the technology survived the rough conditions of harvest and provided reliable data.
