Remarks:
Generally, durum wheat should only be grown in the south and south-western portions of Alberta. Outside of these areas, durum is late maturing and subject to
quality loss. Strongfield yields about 10% higher than AC Barrie in areas of best adaptation. All durum varieties are susceptible to two new races of loose smut and are
generally more susceptible to Fusarium Head Blight than CWRS wheat varieties. AAC Raymore has a solid stem that confers resistance to the wheat stem sawfly. New
registrations: AAC Raymore (DT818), CDC Desire (DT561), CDC Vivid (DT562). AAC Marchwell VB (DT833) and CDC Fortitude (DT570) - Insufficient data to describe.

Yield Test Categories are based on the site means for small plot trials. The defined range for each Yield Test Category is provided in bu/ac. The actual yields for Strongfield
are reported in the Overall and Low, Medium, and High Yield Test Categories. Note that small plot yields may be 10-15% higher than field scale results.
2
Yields are reported
relative to Strongfield. Varieties that are statistically higher (+) or lower (-) yielding than Strongfield are indicated. No symbol after the yield figure indicates no statistical
difference.
3
Maturities rated as: VE = Very Early; E = Early; M = Medium; L = Late; VL = Very Late. The long term average maturity for Strongfield is 105 days and is rated
as Medium (M).
4
Thousand Seed Weight.
5
Resistance/Tolerance Ratings: VG = Very Good; G = Good; F = Fair; P = Poor; VP = Very Poor.
6
Varieties with ratings of Fair (F)
to Very Poor (VP) for loose smut or bunt should be treated with a systemic seed treatment to reduce the potential for infection.
7
Fusarium Head Blight (FHB) infection is
highly influenced by the environment and heading date.
