AAC Tradition

Wheat

Variety Description

Varieties used for comparison: 'Cardale' and 'Carberry'

Summary: The intensity of anthocyanin colouration of the coleoptile of 'AAC Tradition' is medium whereas that of 'Cardale' is strong to very strong and that of 'Carberry' is strong. The anthocyanin colouration of the flag leaf auricles of 'AAC Tradition' is weak to medium whereas it is absent or very weak for both reference varieties. The plants of 'AAC Tradition' are taller than those of both reference varieties.

Description:

PLANT: hard red spring type, semi-erect growth habit at the 5 to 9 tiller stage, heads emerge early to mid-season

SEEDLING: medium intensity of anthocyanin colouration of coleoptile, glabrous lower leaf sheaths and blades

FLAG LEAF: high frequency of plants with recurved/drooping flag leaves, weak to medium anthocyanin colouration of auricles, medium glaucosity of sheath, glabrous blade and sheath

CULM NECK: medium to strong glaucosity, straight
STRAW: very thin pith in cross-section
SPIKE: medium glaucosity, tapering to parallel-sided shape in profile, medium to dense, yellow at maturity, erect attitude, medium hairiness of convex surface of apical rachis segment
AWNS: equal to length of spike, light brown at maturity
LOWER GLUME: medium length, narrow, glabrous
LOWER GLUME SHOULDER: narrow
LOWER GLUME BEAK: medium length

KERNEL: medium to dark red, oval to broad elliptical shape, rounded cheek, very short to medium length brush hairs, narrow to medium-broad width of crease, shallow depth of crease
GERM: medium size

DISEASE REACTION: moderately resistant to moderately susceptible to Fusarium Head Blight (Fusarium graminearum, Fusarium species)

Origin & Breeding History: 'AAC Tradition' (experimental designation 'BW487') originated from the cross '98B25-AS6D01' / 'ND744' conducted at the Agriculture and Agri-Food Canada Cereal Research Centre, Winnipeg, Manitoba in 2003. In 2004, F2 seeds were grown under organic management near Carman, Manitoba and 250 spikes were collected. An F3 bulk was grown near Lincoln, New Zealand during the 2004-2005 winter season and spikes were collected. In 2005 and 2006, the F4 and F5 were grown in Manitoba. In 2007, the F6 lines were yield tested at four locations in western Canada (Brandon, Glenlea, Saskatoon, and Swift Current). Spikes were collected from the yield plots and increased as F7 rows in 2007-2008 at the off-season nursery near Palmerston North, New Zealand. The F7 lines were harvested and evaluated as F8 lines at three locations in western Canada. At advanced stages of variety development, selection criteria included yield, height, tolerance to lodging, maturity and disease resistance. In 2009, the line was advanced as an F9 to the Bread Wheat Organic 'A' test and was subsequently evaluated in the 2010 Bread Wheat Organic 'B' test. In 2011, the line was designated 'BW487' and was entered in the Central Bread Wheat Cooperative test where it was evaluated from 2011 to 2013.

Tests & Trials: Tests and trials were conducted during the 2014 and 2015 growing seasons at the Saskatoon Research and Development Centre in Saskatoon, Saskatchewan. Plots consisted of 5 rows per plot with a row length of approximately 3.35 metres and a row spacing of 18 cm. There were a minimum of 3 replicates arranged in a RCB design. Measured characteristics were based on a minimum of 27 measurements per variety per year. Mean differences were significant at the 5% probability level based on a paired student's T-test.
