The addition of zinc at 20 mg kg−1 to soils in a growth chamber study reduced the shoot Cd concentration of two durum wheat (Triticum turgidum L. var durum) lines at 10 °C, 16 °C, and 22 °C soil temperatures while additions of ammonium nitrate (NH4NO3) and monoammonium phosphate (NH4H2PO4) increased shoot Cd concentrations. Applying Zn with NH4NO3 or NH4H2PO4 reduced shoot Cd concentrations of the plants to levels comparable to the control. Key words: Cd, durum wheat, ammonium nitrate, monoammonium phosphate, Zn

Plant Sci. 95: 189–195. AAC Marchwell durum wheat [Triticum turgidum L. subsp. durum (Desf.) Husn.] is adapted to the durum production area of th Canadian prairies. AAC Marchwell is the first durum genotype registered for commercial production in Canada with the Sm1 gene for antibiosis-based resistance to orange wheat blossom midge [Sitodiplosis modellana (Gehin)]. It combines high grain yield, grain protein concentration, yellow pigment, test weight, and low grain cadmium concentration. AAC Marchwell has similar straw strength, plant height, and days to maturity as Strongfield. AAC Marchwell is resistant to leaf rust, stem rust, stripe rust, common bunt, loose smut, and common root rot. AAC Marchwell has end use quality suitable for the Canada Western Amber Durum class.

The first durum wheat [Triticum turgidum L. ssp. durum (Desf.) Husn.] cultivar developed in Canada was Stewart 63, registered in 1963. The objective of this paper is to document genetic progress in Canadian durum cultivars since that time. The genetic potential for grain yield in the main durum production area increased by about 0.7% per year and shows no sign of tapering off. This genetic potential has been captured in commercial farm yields, which increased by 1.5% per year during the same period. Grain protein concentration tended to increase slightly over the same time period because of the requirement for minimum protein concentration for cultivar release in Canada. Based on a study of two unselected doubled haploid populations, it was estimated that genetic gain for grain yield was reduced by 8 to 15% because of the negative correlation of protein concentration with yield. Yellow pigment concentration of semolina increased during the study period, especially after the mid 1990s, when higher pigment became an important breeding target. Gluten strength has also been increased since the mid 1990s. Grain cadmium concentration was reduced by about 50% to satisfy the requirements of certain export markets. Resistance to leaf and stem rust was maintained in all cultivars released since Stewart 63. In the past 10 yr, breeding has exploited genetic variation in resistance to Fusarium head blight to produce cultivars such as Brigade and CDC Verona with intermediate levels of resistance. There appears to be remaining genetic variability for all major traits in lines currently in registration trials.

Monosomic Analysis

Two genes for stem rust (Puccinia graminis Pers. f. sp. tritici Eriks. & Henn.) resistance were transferred from the Ethiopian durum wheat (Triticum turgidum L) accession St. 464 to Thatcher and Prelude/8* Marquis common wheat. One gene was shown by monosomic analysis to be on chromosome 4B and proved to be Sr7a. Monosomic analysis failed to locate the second gene. It is only partially dominant and conditions resistance to a range of races. Key words: Rust resistance, stem rust, wheat, Puccinia graminis tritici, Triticum aestivum, Triticum turgidum

AAC Stronghold durum wheat [Triticum turgidum L. subsp. durum (Desf.) Husn.] is adapted to the durum production area of the Canadian prairies. Averaged over 3 yr, AAC Stronghold yielded significantly more grain than AC Navigator. AAC Stronghold had a protein concentration significantly less than Strongfield but significantly more than Brigade. AAC Stronghold had a plant height significantly shorter than Brigade, Strongfield, and AAC Cabri, with a lodging score significantly less than Strongfield and AAC Cabri. AAC Stronghold has a solid stem, which confers resistance to cutting by the wheat stem sawfly (Cephus cinctus Norton). AAC Stronghold had low grain cadmium concentration and stronger gluten than Strongfield. AAC Stronghold is eligible for grades of Canada Western Amber Durum.
