Variety Description

Varieties used for comparison: 'HY124-HRS' and 'HY017-HRS'

Summary: At the 5 to 9 tiller stage, the growth habit of 'DASN0013' is semi-erect whereas it is erect for 'HY017-HRS'. The flag leaf of 'DASN0013' is longer than that of 'HY124-HRS'. The frequency of plants with recurved flag leaves is low to medium on 'DASN0013' and very low on 'HY017-HRS'. The intensity of anthocyanin colouration of the flag leaf auricles of 'DASN0013' is strong whereas it is weak for 'HY124-HRS' and medium for 'HY017-HRS'. 'DASN0013' is taller than 'HY017-HRS'. At maturity, the curvature of the culm neck of 'DASN0013' is weak whereas it is strongly to very strongly curved for 'HY124-HRS' and strongly curved for 'HY017-HRS'. The spike density of 'DASN0013' is lax whereas it is medium for 'HY124-HRS'. At maturity, the spike attitude of 'DASN0013' is nodding whereas it is erect for 'HY124-HRS' and inclined for 'HY017-HRS'. The spike colour of 'DASN0013' is brown whereas it is white for both reference varieties. The shape of the shoulder of the lower glume of 'DASN0013' is elevated whereas it is slightly sloping for 'HY124-HRS'. The beak of the lemma of 'DASN0013' is slightly curved whereas it is moderately to strongly curved on 'HY017-HRS'.

BREAD MAKING QUALITY: fair
DISEASE REACTION: resistant to Glume blotch (Septoria nodorum), Powdery mildew (Erysiphe graminis f. sp. tritici), Leaf rust (Puccinia triticina) and Stem rust (Puccinia graminis f. sp. tritici); moderately resistant to moderately susceptible to Septoria tritici blotch (Septoria tritici) and Fusarium head blight (Fusarium graminearum, Fusarium species; based on inoculation trials conducted at the Nairn Research Facility in Ailsa Craig, Ontario in 2013); moderately susceptible to Barley Yellow Dwarf virus

Origin & Breeding History: 'DASN0013' (experimental designation 'SW239-018') is derived from the cross between 'AW571' / 'Sable' made in the lab at the Nairn Research Facility, Ailsa Craig, Ontario in 2005-2006. The F1 seed was planted in the lab in 2006 and was doubled using the doubled haploid (maize pollinated) method. The F2 was planted as a single row in the nursery in the spring of 2007 and was selected for its general appearance and disease reaction. 'DASN0013' ('SW239-018') was entered into a 2-replicate trial in the spring of 2008 and subsequent yield evaluations through 2010. 'DASN0013' was tested for two years in the Orthogonal Hard Red Spring Wheat Trial (Ontario Cereal Crop Committee) during the 2011 and 2012 growing seasons and was supported for registration in January 2013.

Tests & Trials: The comparative trials for 'DASN0013' were conducted during the 2013 and 2014 growing seasons at the Nairn Research Facility, Ailsa Craig, Ontario. Plot size was 4.14 metres squared and consisted of 6 rows. The row length was 3.0 metres with 18 cm spacing between rows. There were 4 replicates in an RCB Design. Measured characteristics were based on 20 measurements per variety per year.
