Variety Description

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

Summary: 'Brigade' has weaker anthocyanin colouration of the coleoptile than 'AC Avonlea' and 'Strongfield'. 'Brigade' has longer awns at the spike tip than 'AC Avonlea' and 'AC Strongfield'. The plants of 'Brigade' are taller than those of the reference varieties. 'Brigade' has longer spikes than 'Commander' and 'AC Navigator'. The awn colour of 'Brigade' is black whereas it is white for 'AC Avonlea' and 'AC Strongfield'.

Description:

PLANT: durum type, erect growth habit
SEEDLING: weak intensity of anthocyanin colouration of coleoptile, no pubescence on lower leaf sheaths, no pubescence on lower leaf blades

FLAG LEAF: low frequency of plants with recurved/drooping flag leaves, glabrous blades and sheaths, moderate anthocyanin colouration of auricles, strong to very strong glaucosity of sheath

CULM NECK: strong to very strong glaucosity
STRAW: thin pith in cross section, no anthocyanin colouration at maturity

SPIKE: tapering shape, dense, yellow at maturity, strong to very strong glaucosity, black awns present, medium length awns, very strongly spreading awn attitude

KERNEL: durum type, amber colour, large, elliptic shape, rounded cheek, short brush hairs, medium width crease, medium deep crease

DISEASE RESISTANCE: resistance to lead rust (Puccinia triticina) and stem rust (Puccinia graminis f. sp. tririci), moderately resistant to moderately susceptible to Tan spot (Pyrenophora triticirepentis), moderately resistant to moderately susceptible to Septoria tritici blotch (Septoria tritici), moderately resistant to moderately susceptible to Fusarium head blight (Fusarium graminearum, Fusarium species), resistant to Common bunt (Tilleria caries, Tilletia foetida)

Origin & Breeding History: 'Brigade' was selected from the cross DT513/DT696 made in 1999. F1 plants were grown in the greenhouse, from which seed was harvested and bulked. The F2 generation was grown in a space-planted field nursery near Lincoln, New Zealand in 1999-2000 and selected for plant height, straw strength and maturity. Individual heads from selected plants were grown as F3 rows near Swift Current in 2000, and selected rows were bulk-harvested and evaluated for test weight, grain pigment and cadmium concentration. Three heads of each selected lines were sown in individual F4 rows in a nursery near Irwell, New Zealand and selected for plant height, straw strength and maturity. The F5 generation was grown in un-replicated yield trials near Swift Current and Regina, Saskatchewan and near Lethbridge and Vauxhall (irrigated), Alberta in 2001, selected for agronomic performance, disease resistance, grain cadmium concentration and quality (protein, pigment, gluten strength). Five heads of each of selected lines were sown in individual F6 rows in a nursery near Irwell, New Zealand and selected for plant height, straw strength and maturity. An un-replicated F7 yield trial was grown near Swift Current, Regina, and Indian Head, Saskatchewan and Lethbridge, Alberta in 2002 and selected for agronomic performance, disease resistance, grain cadmium concentration and quality (protein, pigment, gluten strength). An F5-derived F8 line designated A9909-HD3D was advanced to the Durum Central A Test in 2003, and to the Durum B test in 2004, each grown at six locations in Alberta, Saskatchewan and Manitoba. From 2005 to 2007, A9909-HD3D was assessed in the Durum Cooperative Test as DT773. Leaf and stem rust reactions were assessed in hill plots in the F7 generation in a rust nursery near Glenlea, Manitoba, and Fusarium Head Blight was assessed in an inoculated nursery near Minto, Manitoba. The Cooperative Test entries were screened in inoculated nurseries for the rusts, loose smut and fusarium, Manitoba, and for common bunt near Lethbridge, Alberta.

Tests & Trials: Test and trials for 'Brigade' were conducted during the summers of 2007 and 2008 in Swift Current, Saskatchewan. Plot size was 2.73 meters square and consisted of 4 rows. There were 4 replicates arranged in a RCB design.
