Varieties used for comparison: 'AC Barrie', 'AC Elsa' and 'Goodeve'
Summary: 'CDC Stanley' has a low frequency of plants with recurved flag leaves whereas 'AC Elsa' and 'Goodeve' have absent or very low frequency. The plants of 'CDC Stanley' head earlier than those of 'AC Elsa'. The shoulder of the lower glumes of 'CDC Stanley' is medium in width whereas they are narrow in 'AC Barrie' and 'Goodeve'. The beak of the lowest lemma of 'CDC Stanley' is moderately curved whereas it is straight on 'EC Elsa' and slightly curved on 'Goodeve'.
PLANT: common spring wheat, matures mid-season, erect growth habit, low frequency of plants with recurved flag leaves
SEEDLING (4-leaf stage): very weak intensity of anthocyanin colouration of the coleoptile, glabrous sheath and blade of the lower leaves
FLAG LEAF: absent or very weak anthocyanin colouration of the auricles, medium to strong glaucosity of the sheath, glabrous blade and sheath
CULM/NECK: weak to medium glaucosity, straight at maturity
SPIKE: weak to medium glaucosity, parallel sided, dense, white at maturity, erect attitude at maturity, absent or very sparse hairiness of the convex surface of the apical rachis segment
AWNS: tip awnlets present, very short, white at maturity
LOWER GLUME: medium width shoulder, sloping shoulder shape, medium width and length, glabrous, short slightly curved beak, sparse extent of internal hairs
LEMMA: moderately curved beak
STRAW AT MATURITY: thin in cross section, no anthocyanin colouration at maturity
KERNEL: hard red, medium red, medium size, medium length and width, oval, angular cheek, medium length brush hairs, medium sized round germ, narrow shallow crease, dark colouration with phenol
Origin & Breeding History: 'CDC Stanley' (experimental name 'BW880') was selected from the cross W95132/ 'AC Barrie' made in 1998 at the Crop Development Centre, Saskatoon, Saskatchewan. The F1 was grown in a summer crossing shelter at Saskatoon in 1998. The F2 was bulked at Saskatoon in 1999 with the F3 bulked in a winter nursery and the F4 grown in bulk in Saskatoon in 2000. Seed from single-plant selections were grown out for the F5 and F6 in a rust nursery in Saskatoon and selections made based on rust reaction, plant type and straw strength. A bulked F6 head-row resulted in 'BW880'. The F7 was grown in an unreplicated yield trial nursery at Saskatoon in 2003 and selected for yield under drought conditions. 'BW880' was evaluated as W04086 in preliminary yield trials in 2004 and in the Western Bread Wheat B Test in 2005 and subsequently evaluated in the Western Bread Wheat Cooperative Test from 2006 to 2008.
Tests & Trials: Tests and trials were conducted during the summers of 2009 and 2010 at the Crop Science Field Laboratory of the Crop Development Centre in Saskatoon, Saskatchewan. Plots consisted of 5 rows with a row length of 3.6 meters and a row spacing of 23 cm. There were 4 replications arranged in an RCB design.
