CANADIAN WESTERN AMBER DURUM (CWAD) WHEAT
YIELD
PROTEIN (%) DESCRIPTION
88 62.5 14.4 –
13.7 Highest yields and test weights plus best
rated durum for FHB. The best choice for
durum growers.
Disease package: Resistant to stem and
leaf rust; moderately resistant to stripe
rust
14.6 The first and only midge tolerant durum
wheat in the Proven Seed cereals line-
up. Yields are comparable to the class
leaders.
Disease package: Resistant to stem, leaf
and stripe rust and MS to FHB
14.3 The first solid stem variety. Provides
sawfly resistance for successful harvest
results. Excellent option for high fertility
or irrigation acres.
Disease package: Resistant to stem and
leaf rust; MS to FHB

Interspersed refuge extends midge tolerance
Without an interspersed refuge system,
midge tolerance could break down within 10 years.
If midge tolerant wheat is grown in
a pure stand, only the small
number of naturally occurring
virulent (resistant)
midge survive.
The virulent midge would
mate only with other
virulent midge.
An interspersed refuge system could extend the life
of midge tolerance to 90 years or longer.
A large virulent population
quickly builds and feeds
on tolerant varieties.
Virulent Midge
Tolerant Wheat
Non-virulent Midge
Susceptible Wheat
Non-virulent midge survive
on the 10% susceptible plants
interspersed throughout
the wheat field.
The non-virulent midge
would inter-mate with
virulent midge.
The progeny of this cross would
be non-virulent. This prevents a
build up of a large virulent
midge population.
