Wheat

Variety Description

Varieties used for comparison: 'AC Andrew' and 'Sadash'

Summary: At booting, the flag leaf of ‘AAC Galore' is longer than that of ‘AC Andrew'. The flag leaf sheath and lower side of the leaf blade of 'AAC Galore' have strong glaucosity whereas the flag leaf sheath and lower side of the leaf blade of 'AC Andrew' and ‘Sadash' have a medium degree of glaucosity. At heading, the spike of 'AAC Galore' has a medium degree of glaucosity whereas that of 'AC Andrew' has a weak degree of glaucosity. The lower glume shoulder shape of 'AAC Galore' is straight while the lower glume shoulder shape of ‘AC Andrew' is sloping and that of ‘Sadash' is elevated. The kernel weight of 'AAC Galore' is greater than those of the reference varieties. The crease on the kernel of 'AAC Galore' is shallow while the crease on the kernel of ‘AC Andrew' is of a medium depth and that of ‘Sadash' is deep.

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

Origin & Breeding History: 'AAC Galore' (experimental designations WD29768,19SWSA231 and SWS496) originated from a three-way cross between the varieties ‘AAC Awesome' and ‘Sadash' and the line SWS439(L16022) conducted at Agriculture and Agri-Food Canada, Lethbridge Research and Development Centre in Lethbridge, Alberta in 2016. In 2017, 466 F1-derived double haploids were produced using the maize hybridization technique. The variety was advanced based on plant type, plant height, maturity, yield, disease resistances as well as agronomic and quality traits with one DH line designated WD29768,19SWSA231 in 2019. The line was entered in the Soft White Spring Wheat Registration Trial as SWS496 where it was evaluated from 2020-2022. Breeder seed was established in 2022.

Tests & Trials: The comparative trials for 'AAC Galore' were conducted at Agriculture and Agri-Food Canada, Lethbridge Research and Development Centre in Lethbridge, Alberta during the 2022 and 2023 growing seasons. There were 3 replicates per variety arranged in an RCB design. Plots consisted of 4 rows, each measuring 3.0 metres in length with 0.23 metres between rows. The planting density of 250 plants per square metre, resulted in approximately 2050 plants per variety per year. Measured characteristics were based on a minimum of 20 measurements per variety per year. Mean differences were significant at the 5% probability level based on Student's t-tests. Disease and insect reaction ratings were provided through the disease evaluation of the Soft White Spring Wheat Registration trials from 2020 to 2022.
