Variety Description

Varieties used for comparison: 'Alsen', 'Stettler', 'CDC Go' and 'Superb'

Summary: The plants of 'Carberry' have an intermediate growth habit while it is semi-erect in 'Stettler'. 'Carberry' has shorter flag leaves than those of 'Alsen'. The flag leaves of 'Carberry' are narrower than those of 'Stettler' and 'Superb'. 'Carberry' heads before 'Alsen', 'Stettler', and 'Superb'. 'Carberry' has no anthocyanin colouration of flag leaf auricles while it is medium in 'Superb'. The plants of 'Carberry' are shorter in height than those of 'Stettler'. 'Carberry' has shorter spikes than those of 'Alsen' and 'CDC Go'. The kernel size of 'Carberry' is small to medium while it is medium to large in 'Superb'. 'Carberry' has round embryos while they are oval in 'Alsen' and 'Superb'.


PLANT: common spring type
SEEDLING (at four leaf stage): weak to medium intensity of anthocyanin colouration of coleoptiles, weak pubescence on lower leaf sheath and blade

GROWTH HABIT (at 5-9 tiller stage): intermediate
FLAG LEAF (at booting): medium to high frequency of plants with recurved flag leaves, no anthocyanin colouration on auricles, medium glaucosity on sheath, very weak to weak pubescence blade and sheath

SPIKE: parallel sided, medium density, weak to medium glaucosity, white with striated copper colour, erect attitude at maturity
CULM: medium glaucosity, very weak curvature at maturity
STRAW: thin pith in cross section, weak anthocyanin colouration at maturity
AWNS: present, medium long length, white

LOWER GLUME: narrow to medium width, short to medium length , glabrous
LOWER GLUME SHOULDER: slightly sloping to straight, absent or very narrow width
LOWER GLUME BEAK: slightly curved, short length

KERNEL: hard red type, small to medium size, oval to ovate in shape, predominantly rounded cheek, midlong brush hairs, large round germ, midwide to wide width with shallow to mid-deep crease

PERFORMANCE CHARACTERISTICS: good resistance to shattering, good resistance to drought, fair pre-harvest sprouting tendency, good bread quality

DISEASE REACTION: moderately resistant to Fusarium head blight (Fusarium graminearum, Fusarium species), Stem rust (Puccinia graminis f.sp. tritici), and Loose smut (Ustilago tritici), resistant to Common bunt (Tilletia caries Tilletia foetida), and Leaf rust (Puccinia triticina)

Origin & Breeding History: 'Carberry' (experimental designation 'BW874') is the result of the cross Alsen/Superb made in 2000 at the Semiarid Prairie Agricultural Research Centre of Agriculture and Agri-Food Canada, Swift Current, Saskatchewan. Doubled haploid lines were generated using the maize pollen method. In 2002, individual doubled haploid lines were inoculated with Common bunt and a rust epiphytotic nursery was established. Spikes were selected from 534 disease resistant doubled haploid lines that also matured early and had strong stems of acceptable height. In 2004, agronomic performance was assessed on 191 doubled haploid lines which were grown in Saskatchewan and Manitoba. The experimental doubled haploid line B0065&AK043 was identified based on reaction to Leaf and Stem rust, Loose smut and Common bunt, in response to fusarium, and grain quality and kernel characteristics. The experimental line was evaluated in the Western Bread Wheat 'A_3' test in 2004, Western Bread Wheat B test in 2005, and as 'BW874' in the Western Bread Wheat Cooperative test from 2006 to 2008.

Tests & Trials: The trials of 'Carberry' (experimental designation 'BW874') were conducted during 2008 and 2009 at the Agriculture and Agri-food Canada Research Station, Swift Current, Saskatchewan. A 4 repetition randomised complete block design was planted with each replicate consisting of 4 rows, measuring 3 metres in length spaced 23 cm apart, and seeded at a rate of 220 seeds/square metre. Kernel characteristics were described by the Inspection Division, Canadian Grain Commission. 'Carberry' was also trialed and tested for agronomic characteristics, disease reaction, and end-use suitability in the Western Bread Wheat Cooperative Test 2006-2008.
