Variety Description

Varieties used for comparison: 'AC Avonlea', 'Commander', 'AC Navigator' and 'Strongfield'

Summary: 'Enterprise' has strong to very strong anthocyanin colouration of the coleoptile while it is medium in 'Commander' and weak in 'AC Navigator'. The flag leaf of 'Enterprise' is longer than the flag leaf of 'AC Navigator'. 'Enterprise' has medium glaucosity of the sheath of the flag leaf while it is strong in the reference varieties. 'Enterprise' heads later than 'AC Avonlea'. The plant height of 'Enterprise' is taller than that of 'Commander' and 'AC Navigator'. 'Enterprise' has a thin pith in cross section while it is medium thickness in 'Commander' and 'AC Navigator'. The spike of 'Enterprise' is longer than the spike of 'Commander' and 'AC Navigator'. At maturity, the awns of 'Enterprise' are white while they are black in 'Commander' and 'AC Navigator'. 'Enterprise' has a short lower glume length while it is medium length in 'Commander' and 'AC Navigator'. The thousand kernel weight of 'Enterprise' is lighter than the reference varieties.


PLANT: spring type, durum wheat, erect growth habit at the 5-9 tiller stage, medium to strong glaucosity of the culm at heading, medium maturity

SEEDLING (4 leaf stage): strong to very strong intensity of anthocyanin colouration of the coleoptile, glabrous sheaths and blades of the lower leaves

FLAG LEAF: absent or very weak intensity of anthocyanin colouration of the auricles, medium glaucosity of the sheath, glabrous blade and sheath

STRAW (AT MATURITY): thin pith in cross-section, no anthocyanin colouration
SPIKE: strong glaucosity at heading, tapering profile, dense, awns present, awns longer than the length of the spike
SPIKE AT MATURITY: white, whitish/yellow awns
LOWER GLUME: very narrow shoulder, sloping to slightly sloping shoulder, short, narrow, glabrous, short to medium length beak, slightly to strongly curved beak

KERNEL: durum type, amber colour, medium to large size, elliptical, rounded to angular cheek shape, short to medium length brush hairs, medium to large sized oval germ, medium width crease, shallow to medium depth crease

AGRONOMY: good resistance to shattering

QUALITY: good pastry quality

DISEASE REACTION: resistant to Leaf Rust (Puccinia triticina) and Stem Rust (Puccinia graminis f. sp. tritici), moderately resistant to moderately susceptible to Common Bunt (Tilletia caries, Tilletia foetida) Tan Spot (Pyrenophora tritici-repentis) Septoria Tritici Blotch (Septoria tritici) Spot Blotch (Cochliobolus sativus) and Septoria Nodorum Blotch (Septoria nodorum) and moderately susceptible to Loose Smut (Ustilago tritici) and Fusarium Head Blight (Fusarium graminearum, Fusarium spp)

Origin & Breeding History: 'Enterprise' (experimental designations A0013-KC02, DT787) was selected from the cross 9488C-CK2 / Strongfield made in 2000 at the Semiarid Prairie Agricultural Research Centre, Swift Current, Saskatchewan. F1 plants were grown near Christchurch, New Zealand. The F2 generation was grown near Swift Current in 2001. Individual heads from selected plants, based on height, straw strength and days to maturity were grown in F3 rows in New Zealand. The F4 unreplicated 4-row plots was grown near Swift Current and Regina, Saskatchewan. in 2002 and evaluated for grain yield, days to maturity, straw strength, grain pigment, grain protein concentration and gluten strength. 4 heads per selected line were grown as individual F5 head rows in New Zealand. The F6 unreplicated 4-row plots was grown near Lethbridge, Alberta, Swift Current and Regina, Saskatchewan in 2003 and selected for agronomic performance, disease resistance and quality characteristics. An F4:7 line designated A0013-KC02 was advanced to the Durum Western A-2 Test in 2004. A0013-KC02 was advanced to the Durum 'B' test in 2005. A0013-KC02 was evaluated in the 2006-2008 Durum Cooperative Test as 'DT787'.

Tests & Trials: Tests and trials were conducted during the summers of 2008 and 2009 at the Agriculture & Agri-Food Canada, Semiarid Prairie Agricultural Research Centre, Swift Current, Saskatchewan. Plots consisted of 4 rows with a row length of 3 meters and a row spacing of 0.23 meters. There were 4 replicates arranged in an RCB design. Means of the flag leaf length, days to heading, plant height and spike length are an average of measurements from 2008 and 2009.
