Variety Description

Varieties used for comparison: 'AC Barrie', 'CDC Utmost' and 'CDC Stanley'

Summary: The glaucosity of the culm of 'CDC Plentiful' is weak whereas it is medium on 'CDC Utmost'. The plants of 'CDC Plentiful' are shorter than those of 'AC Barrie'. The lower glume of 'CDC Plentiful' has a slightly sloping shoulder shape whereas 'CDC Utmost' has a straight shoulder. The lower glume of 'CDC Plentiful' is short whereas it is of medium length on 'AC Barrie' and 'CDC Stanley'. The lower glume of 'CDC Plentiful' is of medium width whereas the reference varieties are narrow. The beak shape of the lowest lemma of 'CDC Plentiful' is slightly curved whereas it is straight on 'AC Barrie' and 'CDC Utmost', and moderately curved on 'CDC Stanley'.

DISEASE RESISTANCE: moderately resistant to Fusarium head blight (Fusarium graminearum, Fusarium species), moderately resistant to moderately susceptible to Common Bunt (Tilletia caries, Tilletia foetida) and Leaf Spots (Pyrenphora tritici-repentis, Septoria nodorum, Septoria avenae f. sp. triticea, Pseudoseptoria sp., Cochliobolus sativus) and resistant to Loose smut (Ustilago tritici), Leaf Rust (Puccinia recondita) and Stem Rust (Puccinia graminis f. sp. tritici)

Origin & Breeding History: 'CDC Plentiful' (experimental designation 'PT580') was selected from the cross 'BW282'/ 'CDC Go' made in the summer of 2001 at the Crop Development Centre, Saskatoon, Saskatchewan. The F1 was grown in the field during the summer of 2002 with the F2 bulked in the greenhouse in Saskatoon that fall. The F3 was grown in a rust nursery in Saskatoon in 2003 and selected based on rust reaction, plant type and straw strength. An F4 head row was grown in a rust nursery in 2004 and bulked to derive 'PT580'. The F5 was grown in an unreplicated yield trial nursery at Saskatoon in 2005 and selected based on yield, height and straw strength. 'PT580' was evaluated as W06023 in replicated tests in 2006 and in the Western Bread Wheat B Test in 2007. 'PT580' was subsequently evaluated in the Parkland Cooperative Test from 2008 to 2010.

Tests & Trials: Tests and trials for 'CDC Plentiful' were conducted during the summers of 2011 and 2012 at the Crop Science Field Laboratory of the Crop Development Centre, University of Saskatchewan, Saskatoon, Saskatchewan. There were 4 replications arranged in an RCB design. Plots consisted of 5 rows with a row length of 3.6 metres and a row spacing of 23 cm.
