Technical Bulletin: Taza Spring Triticale

Taza is derived from the cross 93P200/88L012 produced at the Field Crop Development Centre, Lacombe in 1994. 93P200 is a CIMMYT germplasm introduction (Stier-5-2/ASAD//Nimir-3). 88L012 is a reduced awn (awnletted) spring triticale population from a complex cross related to the spring triticale varieties Bunker and Tyndal as well as the winter triticale varieties Bobcat, Luoma and Metzger. The awnletted characteristic in 88L012 came from a triticale x spring wheat cross (RL4137) back crossed several times to spring triticale. The F₂-F₃ was grown in the field as modified bulks in 1995-1996 and subjected to selection for degree of awn reduction and agronomic type. The F₄-F₅ generation was handled in a classical pedigree (ear to row) fashion using plant type, degree of awn reduction as the primary selection criteria and Taza was selected for advancement. During 1999 (F₆) through 2004 (F₁₁), T198 was evaluated in the yield trial (Lacombe, Stettler and Trochu) system as well as various disease and forage trials. In 2005 (F₁₂) Taza was evaluated in the Spring Triticale B test. Taza was finally entered in the Western Spring Triticale Co-op in 2006 (F₁₃) and has been in the registration trial for 4 years (F₁₆).

The awnletted characteristic in Taza comes from the same source as the winter triticale varieties Bobcat, Luoma and Metzger as well as the spring triticale varieties Bunker and Tyndal.

End Use

Taza is an awnletted (reduced awn expression) standard height triticale line intended for use as a feed grain conserved forage, swath grazing crop and potentially for industrial use. Taza is adapted to the Canadian prairie provinces.

Strengths

Taza yields similar to Pronghorn but is equal to or higher than AC Ultima and AC Certa. Taza has a reduction in awn expression similar to Bunker and Tyndal.
This line has good lodging resistance, good test weight, and high kernel weight.
Taza is MS to MR for FHB resistance; it is resistant to leaf rust and stem rust.

Weaknesses

Lower resistance to FHB than Pronghorn and 2 days later maturing than AC Ultima. Taza has a lower falling number than AC Ultima.
