Wheat

Variety Description

Varieties used for comparison: 'AAC Penhold', 'AAC Ryley', 'CDC Terrain' and '5702PR'

Summary: At the 4 leaf stage, the lower leaf blade of the seedling of 'CDC Reign' is glabrous whereas the lower leaf blade is pubescent on the seedling of 'AAC Penhold'. At booting, the frequency of plants with recurved flag leaves is high for 'CDC Reign' whereas it is absent or very low to medium for '5702PR' and very high for 'AAC Penhold'. The intensity of anthocyanin colouration of the flag leaf auricles of 'CDC Reign' is absent or very weak whereas it is strong for 'AAC Penhold' and 'CDC Terrain'. The flag leaf of 'CDC Reign' is wider than that of 'AAC Penhold' and '5702PR'. The glaucosity on the flag leaf sheath of 'CDC Reign' is medium whereas it is strong for that of 'AAC Penhold' and weak for that of '5702PR' At heading, the glaucosity on the spike of 'CDC Reign' is weak to medium whereas the glaucosity is absent to very weak on the spike of '5702PR' and strong on the spike of 'AAC Penhold'. At maturity, the plants of 'CDC Reign' are taller than those of 'AAC Penhold' and shorter than those of 'CDC Terrain'. The spike of 'CDC Reign' is of medium density whereas the spike of 'CDC Terrain' is dense. Excluding the awns, the spike of 'CDC Reign' is longer than that of 'AAC Penhold' and 'CDC Terrain'. The lower glume of 'CDC Reign' is medium length whereas those of the reference varieties are long. The extent of internal hairs on the lower glume of 'CDC Reign' is sparse to medium whereas it is high on the lower glume of '5702PR'.

DISEASE REACTIONS: resistant to Leaf rust (Puccina recondita); moderately resistant to Stem rust (Puccinia graminis f. sp. tritici), Stripe rust (Puccina striiformis) and Loose smut (Ustilago tritici); moderately resistant to moderately susceptible to Fusarium head blight (Fusarium graminearum, Fusarium species) and moderately susceptible to Common bunt (Tilletia caries, Tilletia foetida)

Origin & Breeding History: 'CDC Reign' (experimental designations HY08.34.182 and 'HY2062') originated from the cross between ACS51638, as the female parent, and 'Alsen', as the male parent, conducted in the summer of 2008 at the Crop Development Centre of the University of Saskatchewan in Saskatoon, Saskatchewan. The F1 generation was increased at a contra-season nursery near Christchurch, New Zealand. The F2 and F3 generations were increased in bulk in Saskatoon and near Christchurch in 2009. In 2010, F4 plants with suitable plant height, maturity and straw strength were selected and grown as F5 head rows in a leaf and stem rust nursery in Saskatoon in 2011. Three random spikes from the head rows with suitable plant height, maturity and leaf and stem rust resistance were selected. Head rows were evaluated again in 2012 in leaf and stem rust nurseries as well as for Fusarium head blight resistance in Carmen, Manitoba. In 2013, the line designated, as HY08.34.182, was selected and evaluated in un-replicated yield trials near Saskatoon and in artificially inoculated nurseries for common bunt, leaf and stem rust in Saskatoon and for Fusarium head blight in Carmen. HY08.34.182 was evaluated for agronomic traits, advanced in replicated yield trials at various locations in Saskatchewan and Alberta in 2014 and also assessed in disease resistance trials conducted in Saskatoon, Saskatchewan and Carman, Manitoba. HY08.34.182 was evaluated in the High Yield Wheat B-Tests in 2015 and in the High Yield Red Wheat Co-operative Trials as 'HY2062' from 2016 to 2018. Selection criteria were plant height, maturity, straw strength, disease resistance, yield, thousand kernel weight, test weight, and quality traits such as grain protein, falling number, and baking qualities.

Tests & Trials: The comparative tests and trials of 'CDC Reign' were conducted during the 2018 and 2019 growing seasons at the Crop Science Field Laboratory, University of Saskatchewan, Saskatoon, Saskatchewan. There were three replications arranged in a RCB Design. Plots consisted of 5 rows spaced 20 cm apart. The plot size was 4.0 square metres with a minimum density of 300 plants per square metre. Measured characteristics are based on 20 measurements per variety each year. Mean differences are significant at the 5% probability level based on a paired Student's T-test. Disease ratings for 'CDC Reign' were provided through the Disease Evaluation team of the Prairie Recommending Committee for Wheat, Rye and Triticale and the Prairie Grain Development Committee from the High Yield Red Wheat Co-operative Registration Trials conducted from 2016 to 2018.
