Variety Description

Varieties used for comparison: 'AAC Nicolas' and 'CDC Orrin'

Summary: The flag leaf of 'AAC Anthony' is shorter than the flag leaf of 'AAC Nicolas'. The plants of 'AAC Anthony' head later than the plants of 'CDC Orrin'. The glume of 'AAC Anthony' has a medium degree of glaucosity while that of 'AAC Nicolas' has weak glaucosity. At maturity, the 1000 kernel weight of 'AAC Anthony' is greater than that of 'AAC Nicolas'. The kernel of 'AAC Anthony' is longer and wider than that of 'AAC Nicolas'.

Description:

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

STEM: medium to dense pubescence above upper culm node, medium density of pubescence below upper culm node

LOWER LEAF: absent to very sparse pubescence on sheath and blade at the 5 to 9 tiller stage
LEAF (AT BOOTING): medium green, absent or very sparse pubescence on margin of leaf below flag leaf, medium glaucosity at green stage

PANICLE (SHORTLY AFTER HEADING): equilateral/symmetrical orientation of branches, medium density, semi-erect attitude of branches, less than 30 degree angle between rachis and dominant side branch
LOWEST PANICLE NODE: few hairs or spines
SPIKELET: semi-abscission type separation, semi-nodding attitude, two grains
GLUME: medium glaucosity
RACHILLA: medium length between primary and secondary floret, absent or very short grooves, sparse pubescence
LEMMA: weak glaucosity, small extent of lateral overlap on palea, white at maturity, absent or very sparse pubescence on lateral and dorsal surface, medium tendency to be awned

KERNEL: no basal hairs, white
GROAT: medium density of pubescence
SCUTELLUM: pointed tip, medium size

AGRONOMIC CHARACTERISTICS: fair lodging resistance

Origin & Breeding History: 'AAC Anthony' (experimental designation OA1627-1) originated from a cross conducted between two lines designated SA100100 and OA1331-5-5 at the Agriculture and Agri-Food Canada, Ottawa Research and Development Centre in Ottawa, Ontario on November 11, 2013. The line was advanced from the F1 to F4 generation in the greenhouse, and a population of 240 F4:5 panicles were grown as hill plots in 2015. After visual selection in 2015 and 2016 and yield trials in 2017-2018 and 2019-2020, an F5 line was designated as OA1627-1 in 2017. Selection criteria used in the development of 'AAC Anthony' were based on plant and seed characteristics, yield, agronomic and quality data. Breeder seed was established at the F5:10 generation in 2020.

Tests & Trials: The comparative trials for 'AAC Anthony' were conducted at Agriculture and Agri-Food Canada, Central Experimental Farm in Ottawa Ontario in the 2021 and 2022 growing seasons. The trials were conducted using a RCB design consisting of 4 replications per variety. Each plot consisted of 6 rows spaced 18 cm apart, with a row length of 3.8 metres. The planting density of 350 seeds per square metre resulted in approximately 5600 plants per variety per year. Measured characteristics were based on a minimum of 20 measurements per variety per year except for kernel weight which was based on a minimum of 4 measurements per variety per year. Mean differences were significant at the 5% probability level based on a paired Student's t-test.
