Spring wheat acreage will increase again in 2003 across
eastern Ontario, the result of good yields and high prices. Following are
some characteristics for selected spring wheat varieties, which hopefully
will help you with your selection.
C Brio — This variety has become the standard for
eastern Ontario. It has excellent milling and baking characteristics with
a high falling number and average protein levels. It has no issues on
marketing. AC Brio is the highest yielding Pool C variety in eastern
Ontario. Straw production is good mainly made up of long stems.
It has a tendency to lodge in high production/fertility
environments but doesn’t go right flat like barley, allowing the grain
to be still picked up.
AC Brio is susceptible to mildew and has shown a yield
response to Folicur application. Seed supplies will have trouble keeping
up with demand for this popular variety.
606 — Yielded comparable to AC Brio in 2002 and
slightly less in 2001 plots. In high yield situations it will out yield AC
Brio. 606 has excellent stand-ability, comparable to AC Walton and much
better than AC Brio.
Moisture levels were higher at harvest this year than
Brio, likely related to better plant health. It kept growing longer than
Brio. It has excellent leaf disease tolerance and is less likely to
require Folicur for leaf disease control. 606 has high straw yields even
though it is 4" to 6" shorter than Brio.
It has more leaf than other varieties and the leaves
don’t fall off the stem at harvest like other varieties. It has higher
protein levels than Brio but a lower falling number.
A low and variable falling number in 2002 has made the
Wheat Board look to subpool 606 in 2003. It will need to be kept separate
from Pool C varieties and may be discounted slightly due to milling
quality.
Alsen — A newly available variety in 2002, it
yielded about 10 % less than AC Brio. Alsen has improved fusarium
tolerance over other varieties. Therefore, if you are planting wheat into
a field with fusarium risk (a previous crop of corn or wheat), then this
is a variety you should consider planting. Fusarium tolerance takes
priority over yield in these situations. Alsen has better standability
than Brio but not as good as 606. Pooling status is still to be finalized
on Alsen.
Celtic — This is the old standard that was widely
grown in the past. Celtic has good milling characteristics and no
marketing issues. It yields on average about 10% lower than AC Brio.
It should not be seeded following corn as yield will
drop off when following other crops.
AC Barrie — Barrie yields comparable to Celtic.
It has good milling characteristics and no marketing issues.
A good choice where growing conditions are tough on
really heavy or light soils. Avoid planting it on fields with a history of
lodging problems.
AC Walton- This is a later maturing variety that has yielded well
in the past when managed. Walton needs to be sprayed with Folicur for leaf
disease control, especially rust. It has excellent standability with a
tough stem. It is not widely grown recently because it is designated to
Pool D.
