Shorty Baudin lNins hearts and minds, jury still out on Hamelin byMikePerry

Short, tough and plump: early growers of Baudin look over a winning combination of traits.

IT COULD be called generational change and it's been a long time corning, but malting barley producers in WA are set for a big change if the new provisional malting varieties HamelinPBR logo and BaudinPBR logo live up to their promise.

Big reputations are on the line as these replacements for Stirling and GairdnerPBR logo enter commercial production. So, how have seed growers found the new varieties perform 'on-farm'?

BaudinPBR logo - yield and good grain size in the one package

Mark and Heather Adams and Mark's parents. Colin and Edna, together count more years of experience than they care to remember with malting barley on their ' Yaralla' property, 30 km east of Mount Barker. WA. "Stirling had its day but never fulfilled our yield potential," said Mr Adams.

"FranklinPBR logo" gave us yield, but most of the grain had to be screened before delivery. At least we have not had to do that with GairdnerPBR logo", but with BaudinPBR logo we may have yield and good grain size in the one package."

Selected from a Stirling/FranklinPBR logo cross, Baudin" is a 'GairdnerPBR logo' replacement' with shorter stature, excellent straw strength and head retention, slightly plumper grain compared to GairdnerPBR logo and excellent malting quality. In trials, BaudinPBR logo's grain yields are generally equivalent to those of GairdnerPBR logo. Some data suggest that GairdnerPBR logo retains a yield advantage in high-rainfall areas, while BaudinPBR logo has an advantage at yield levels below 2.5 t/ha.

Two years of growing BaudinPBR logo have left the Adamses with some strong impressions of the new variety. "It's short," said Mr Adams. "Lodging and head loss cost us 8-10 per cent of our GairdnerPBR logo last year just because of two or three hot windy days, compared to no losses on the BaudinPBR logo.

"We are 100 per cent crop and 100 per cent stubble retention. so straw handling is important. Barley may not be as tough as wheat. but the short stature of BaudinPBR logo means less straw to handle when it comes to seeding," he said.

Mark Adams also has some interesting observations on disease. "With the short height, we get better spray penetration and seem to get better disease control. even though BaudinPBR logo is just as susceptible as GairdnerPBR logo."

Figures back this up - in 2002 the Adams' early-sown GairdnerPBR logo needed three sprays but still carne in at 22 per cent screenings, while BaudinPBR logo in the same paddock needed only two sprays and had 11 per cent screenings. "Yes, BaudinPBR logo's naturally plumper grain helped, but I believe that more effective disease control was just as important," Mr Adams concluded.

"It goes by the book" is Ray Harrington's experience of three years of BaudinPBR logo. Last year Ray and Tim Harrington's malting evaluation crop went 4.9 tlha at 5 per cent screenings compared to 5 tonnes and 12 per cent screenings for the GairdnerPBR logo control. "It's an unassuming crop. easy to harvest and tends to go better than it looks," according to Mr Harrington.

Based at Cordering. halfway between Darkan and Boyup Brook, Mr Harrington is well known for his innovative machinery and matching farming systems. "We swath our barley at 40 per cent moisture with a desiccant spray applied underneath the swather for ryegrass control, and then pick up and chop the straw through the header," he said. A vote of confidence?

"Eighteen hectares of BaudinPBR logo last year, 350 ha this year!" was Mr Harrington's reply.

More ambivalent about HamelinPBR logo

Bred from a Stirling/Harrington cross. HamelinPBR logo is a slightly higher-yielding, improved malting quality replacement for Stirling. It is of similar height with a slight improvement in lodging resistance, produces grain that is generally brighter and has a slightly higher level of screenings (2-4 per cent).

Unfortunately it retains the disease susceptibility of Stirling and has inherited the potential for pre-harvest sprouting from its Canadian parent.

Peter and Tony Boyle of 'Warawong' in the heart of WA's Avon Valley have grown both HamelinPBR logo and BaudinPBR logo. "HamelinPBR logo looks okay - so similar to Stirling, it's hard to pick," says Mr Peter Boyle. "But it's BaudinPBR logo we are looking forward to."

The Boyles moved to GairdnerPBR logo for its yield (up to 1 t/ha greater) and $5/tonne premium over Stirling, but have had to use their on-farm grader or CBH's Metro Grain Centre cleaning service to take out the screenings in most years. "That's $15/tonne in costs we could pick up straight away it BaudinPBR logo's plumper grain comes through." said Mr Boyle.

This year Peter Boyle is putting BaudinPBR logo to the test. "Sowing in June we would normally use Stirling (or HamelindPBR logo), but if BaudinPBR logo is as flexible as people say and the screenings are not too bad, we will go with just the one variety," he said.

Similar thoughts are going through the minds of John and Alison Tuckett at 'Aurora', 45 krn south of Kojonup on the Albany Highway. "We are a mixed fanning operation, 50:50 livestock and crop, and a big mix of soil types, and we can't do everything at the saIne time," said Mr Tuckett.

"We tried GairdnerPBR logo, but went back to Stirling because we knew that we could sow in the first half of June and always make malting. GairdnerPBR logo had the yield advantage, but we couldn't always get it into the sowing window - and even if we did, the screenings dropped us out of malting more often than not."

The Tucketts were pleased with their 2002 BaudinPBR logo crop grown for commercial malting evaluation and have 200 ha of BaudinPBR logo this year.

And HamelinPBR logo? "It could have a future, but we will wait and see," said Mr Tuckett. HamelinPBR logo and BaudinPBR logo have been registered for Plant Breeder's Rights. Both varieties have been released as 'Provisional Malting'. Commercial malting evaluation is continuing in 2003 and, on completion, the varieties will be classified as General Malting or, alternatively, as Feed.

This is likely to occur at the end of 2003 for BaudinPBR logo and following the 2004 season for HamelinPBR logo. A crop improvement royalty will be applied to both varieties.
