Redcliff hard red spring wheat

Abstract

Redcliff hard red spring wheat was developed at the University of Alberta using a modified bulk breeding method. In 3 years of evaluation in the Parkland Cooperative test from 2018 to 2020, Redcliff produced 7.3% more grain and matured 1.9 days earlier than the highest yielding check Carberry. Redcliff had 3.9 cm taller plants than Carberry but shorter than the other checks and displayed good lodging tolerance. The test weight of Redcliff was slightly higher than Carberry and Parata but lower than Glenn. The grain weight of Redcliff was higher than Parata and similar to the other checks. Grain protein content was within the range of the checks. Redcliff was rated “resistant” to the prevalent races of stem rust, “resistant” to “moderately resistant” to Fusarium head blight, “intermediate” to leaf and stripe rusts, whereas “moderately susceptible” to common bunt. Three years of end-use quality evaluation have indicated that Redcliff is acceptable for the Canada Western Red Spring wheat market class, with improvements in flour yield.
