Prairie malting barley producers
looking for new, high-yielding varieties will soon need to
search no further than CDC Copeland and CDC Select, two of the
latest two-row malting barleys developed by the University of
Saskatchewan Crop Development Centre (CDC).
“CDC Copeland and CDC Select represent a substantial jump in
yield compared to previous releases from our two-row breeding
program,” says Dr. Bryan Harvey, the long-time CDC malt barley
breeder. The varieties out-yield Harrington by an average of 16
percent and 11 percent respectively across the Prairies, and
feature several other production and market benefits.
CDC Copeland and CDC Select are performing well in commercial
testing and could be widely available to western Canadian
producers in as soon as two years, says Harvey. The varieties
were developed in part with support from the Barley Check-off
Fund, administered by Western Grains Research Foundation
In addition to high yield, the two varieties feature improved
kernel plumpness and hull adherence, says Harvey. Both have a
standard disease package, but with improved net blotch
resistance and what appears to be better sprouting resistance.
CDC Copeland’s tolerance to Fusarium Head Blight is as good as
any comparable variety, while CDC Select is more susceptible to
the disease. Where the varieties part ways is on quality. CDC
Copeland has a “European” quality package, while CDC Select’s
quality is tailored for North American brewers.
“Both varieties are adapted across Western Canada, but CDC
Copeland is especially suited for West Central Saskatchewan,
where it outyields Harrington by 26 percent,” he says.
While farmers are interested in CDC Copeland’s yield
performance, the variety is raising eyebrows in malting and
brewing circles for its unique quality package. “It has a very
unusual combination of low beta-glucan and soluble protein
levels in the malt,” explains Harvey. “Typically, one is low and
one is high or vice-versa.”
In the brewing process, having
low levels of both beta-glucan and soluble protein helps prevent
poor flavouring and hazing, he says. “In most barley varieties,
high-stress conditions, such as the 2001 drought, can cause
beta-glucan levels to rise too high, which is possible to
overcome by extending germination in the malting process, but by
doing that, you often increase soluble protein levels. The
beauty of CDC Copeland is that maltsters have a lot of room to
bring down beta-glucan levels to their particular specifications
without having to worry about the soluble protein shooting up.”
So far, both varieties look promising in commercial testing,
says Harvey. “Maltsters are very pleased with both varieties and
limited brewing tests show they are satisfactory.”

The Barley Check-off Fund contributes over $600,000 annually to
barley breeding programs in Western Canada. Breeding targets
include improved agronomy, disease resistance and quality for
both feed and malting varieties.
