TITLE:
Off-station
Spring
Wheat
and
Triticale
variety
investigations.
YEAR:
1988
LOCATION:
Western
Triangle
Research
Center/
Conrad/
MT.
PERSONNEL:
Gregory
D.
Kushnak/
Ron
Thaut/
and
Larry
Christiaens/
Research
Center/
Conrad;
and
the
MSU
Dept.
of
Plant
&
^
Soil
Science.
Off-station
dryland
spring
wheat
and
triticale
variety
trials
were
grown
near
Cut
Bank/
Oilmont/
Choteau/
and
Sun
River;
and
irrigated
Fairfield.
Soil
moisture
on
fallow
was
good
during
planting
at
most
locations/
contributing
to
fair
yields
in
spite
of
the
below-normal
rainfall
of
1988.
Soil
moisture
on
recrop
was
insufficient
to
support
plant
growth
beyond
the
seedling
stage;
and
therefore
all
recrop
trials
were
lost.
"
Data
for
the
spring
wheat
tests
at
the
various
locations
are
presented
in
Tables
1-5.
Substantial
sawfly
damage
occured
at
Choteau.
Sawfly
resistant
varieties
in
the
tests
included
three
(-1
semidwarfs
Glenman/
Rambo
and
Cutlass;
and
four
standard
height
varieties
LeW/
Fortuna/
Lancer/
and
Amidon.
Rambo
and
Amidon
showed
only
partial
resistance
to
sawfly
in
1988.
Amidon
is
a
new
release
from
North
Dakota.
Among
the
sawfly
resistant
and
semi-resistant
varieties/
Glenman
and
Rambo
had
the
highest
3-year
average
yield
at
all
fn
locations
except
Choteau/
where
Lew
ranked
highest.
Lancer
yielded
low
at
several
locations/
and
exhibited
very
weak
straw.
Lancer/
Fortuna
and
Cutlass
generally
ranked
highest
for
protein/
„
followed
by
Lew/
Rambo/
and
Glenman.
Spring
triticale
trials
were
grown
on
dryland
at
Sun
River/
Cut
Bank/
Oilmont/
and
Choteau.
Eight
triticale
varieties
were
tested:
Karl
and
Kramer/
two
semidwarfs
from
North
Dakota;
Marval
from
South
Dakota;
Carman/
Welsh/
and
Wapiti
from
Canada;
Juan
from
California;
and
Whitman
from
Washington.
Spring
wheat
was
included
in
the
trials
for
comparison.
Data
from
the
triticale
tests
are
presented
in
Tables
5-8.
Wapiti
ranked
high
for
yield
at
all
locations/
but
its
tall
straw
"
appeared
weak.
Juan
and
Whitman
were
too
late
to
mature/
resulting
in
very
low
yield
and
test
weight
at
most
locations.
On
a
pounds/
acre
basiS/
the
top
yielding
triticale
variety
at
the
respective
"
locations
yielded
90%
of
spring
wheat
at
Cut
Bank/
123%
at
Oilmont/
and
144%
at
Choteau.
The
test
weight
of
triticale
averaged
approximately
50
pounds/bushel/
and
the
yields
were
calculated
„
on
that
basis.
All
varieties
suffered
moderate
sawfly
damage.
Ergot
was
not
detected
in
the
triticale
plots.
However/
ergot
has
been
observed
in
some
fields
of
triticale
in
the
"
Triangle
area.
