North Kellerberrin grower Dennis Reid pitched Tomahawk CL against the new RGT Marsh in strip trials this year – and the results were not what he expected.
Both varieties are considered powerhouses for Western Australian broadacre farmers, who now face the challenge of choosing from more than 50 wheat options, with new releases each season.
Tomahawk CL has proven to be the highest-yielding Clearfield wheat in WA and has a grain size and test weight similar to Scepter.
RGT Marsh is a quick-mid variety in terms of season length/phenology, sitting between Vixen, Scepter and Tomahawk CL and giving it a very flexible fit across WA environments.
Mr Reid seeded Tomahawk CL and RGT Marsh in adjacent strips.
RGT Marsh averaged 3.72 tonnes per hectare, compared with Tomahawk CL at 3.65t/ha.
The hectolitre weight of RGT Marsh was 79.2, compared with Tomahawk CL at 74.6 – indicating fewer small grains – while protein was slightly higher in Tomahawk CL at 9.3, compared with 8.8 in RGT Marsh.
“We were really happy with both varieties, but – along with its good grain performance – the RGT Marsh was also noticeably easier to harvest,” Mr Reid said.

Mr Reid farms with his wife, Sonia, and is using a John Deere 680 and John Deere 780 harvester, both fitted with Harrington Seed Destructors.
This year, the Reids seeded 2200 hectares of their 4000ha property to wheat.
They used Tomahawk CL, Catapult, Calibre and RGT Marsh across 110ha to bulk up seed for next season.
Their canola program covers 1100ha planted to Regiment XC and Hunter TF, and barley comprises 270ha of Maximus.
Smaller areas of lupins and oats round out the program.
Aside from the wheat trial, Mr Reid said they had already harvested 465ha of canola, achieving above-average yields of about 2.4t/ha with excellent oil content.
Like many farmers, he described the season as one “ridden by the seat of your pants”.
“We got early March and April rain, but none in May, only 29 millimetres in June, 36mm in July and then a saving grace of 106mm in August,” he said.
“That August rain changed the game – and another 27mm in September really finished things off nicely.”
Choosing wheat varieties each year remains a difficult decision for the Reids, who require a long-season line, a mid-season line and a specific IMI-tolerant option.
“RGT Marsh might just fit into our system as the main mid-season, non-IMI-tolerant variety,” Mr Reid said.
“It seems to have a good disease package, and it handled this year’s tough conditions really well.
“We’re definitely going to use it as part of the 2026 wheat program, but we’re waiting on its classification before deciding how much to plant.”
RAGT broadacre business development manager, David Peake, said RGT Marsh had been bred specifically for WA Wheatbelt conditions.
He said the late-season rains across much of the agricultural region appeared to have given this new variety an edge in low to mid-rainfall areas, compared with quicker-maturing lines, such as Vixen and LRPB Anvil, which can have capped yields in favourable finishes.
Mr Peake said RGT Marsh had been planted from Mullewa to Beaumont, and, where late rains fell, its performance was particularly strong.
“Feedback from around the State is that RGT Marsh has yielded above the farm average on many properties,” he said.
“With robust performance in tough seasons and standout disease resistance, this variety has proven itself over multiple years where others stumble.
“RGT Marsh is a new yield weapon for WA growers.”
Mr Peake said three years of National Variety Trials across 47 sites showed RGT Marsh to be a consistently strong performer across all WA zones, particularly in May-June sowings.
“Its upright leaves give better light interception, and it has strong resistance to rust, Septoria nodorum and black point,” he said.
“It offers excellent grain quality with low screenings, good grain size and solid sprouting tolerance.
“AH or APW classification is pending from Grains Australia.”
Mr Reid still has 600ha of canola to harvest before moving on to the balance of his wheat crop.
“Our harvest results so far have been amazing, given the season we had,” he said.
“If only grain prices were a bit better.”
