Variety Description

Varieties used for comparison: 'Carberry', 'CDC Landmark' and 'CDC Hughes'

Summary: The intensity of anthocyanin colouration for the coleoptile of 'AAC Alida' is strong whereas it is weak for 'Carberry', of weak to medium intensity for 'CDC Landmark' and medium intensity for 'CDC Hughes'. At booting, the frequency of plants with recurved flag leaves is low to medium for 'AAC Alida' whereas 'CDC Landmark' and 'CDC Hughes' have a medium to high frequency of recurved flag leaves. The intensity of anthocyanin colouration of the auricles on the flag leaf is medium for 'AAC Alida' whereas it is absent or very weak for the reference varieties. 'AAC Alida' has a medium degree of glaucosity on the flag leaf sheath whereas the glaucosity is weak for 'CDC Landmark' and 'CDC Hughes'. At maturity, the plants of 'AAC Alida' are taller than those of the reference varieties. In cross section, the straw pith of 'AAC Alida' is thin whereas it is of medium thickness for 'CDC Landmark' and 'CDC Hughes'.

Description:

PLANT: common wheat, spring type, intermediate growth habit at 5 to 9 tiller stage, low to medium frequency of plants with recurved flag leaves

SEEDLING (4 LEAF STAGE): strong intensity of anthocyanin colouration of coleoptile, glabrous lower leaf sheaths and blades

FLAG LEAF: medium intensity of anthocyanin colouration of auricles, medium glaucosity of lower side of blade and sheath, glabrous blade and sheath

CULM NECK: absent or very sparse glaucosity
STRAW (AT MATURITY): thin pith in cross-section, no anthocyanin colouration

SPIKE: medium glaucosity at heading, tapering shape in profile, medium density, white at maturity, medium length, erect attitude
AWNS: shorter than or equal to spike length, white at maturity

KERNEL: hard red type, dark red

INSECT REACTION: resistant to Orange Wheat Blossom Midge (Sitodiplosis mosellana)

Origin & Breeding History: 'AAC Alida' (experimental designations B0867&AK049 and BW980) originated from the cross between 'Carberry' and '99B61-AY30B5' made in 2008 at the Swift Current Research and Development Centre of Agriculture and Agri-Food Canada in Swift Current, Saskatchewan. Double haploid lines were generated using the maize pollen method. In 2009, the first subset of 146 individual double haploid lines were inoculated with Common bunt and a rust epiphytotic nursery was established. Spikes were selected from 104 disease resistant double haploid lines that also matured early and had strong stems of acceptable height. In 2009, seeds from each spike were grown out in 2 metre long rows near Irwell, New Zealand. These lines were assessed for maturity, plant height, resistance to lodging and resistance to shattering and harvested as individual rows for subsequent trialing. In 2010, 68 double haploid lines were assessed for agronomic performance in nurseries near Swift Current and Indian Head, Saskatchewan and Lacombe, Alberta and selected lines screened for disease reaction, grain quality and kernel characteristics. The line designated as B0867&AK049 was evaluated in the Western Bread Wheat A4 test in 2011, Western Bread Wheat B test in 2012, and as BW980 in the Western Bread Wheat Cooperative test from 2013 to 2016.

Tests & Trials: The comparative tests and trials for 'AAC Alida' were conducted at the Agriculture and Agri-Food Canada, Swift Current Research and Development Centre during the 2017 and 2018 growing seasons. There were 4 replicates of 4.6 square metre plots arranged in an RCB Design. Each plot consisted of 4 rows, each 4 metres long, with an inter-row spacing of 23 cm. The planting density was 220 plants per metre squared, with 3200 plants per variety grown per year. Measured characteristics were based on 20 measurements per variety per year. Mean differences were significant at the 5% confidence probability level based on LSD values.
