Varieties used for comparison: 'Goslin' and 'Aylmer'
Summary: 'Bradley' has absent to very sparse pubescence on the margins of the leaves while it is sparse for 'Goslin'. The flag leaf of 'Bradley' is shorter than the reference varieties. 'Bradley' has an equilateral orientation of the branches of the panicle while it is intermediate for 'Aylmer'. The scutellum of 'Bradley' is medium sized while it is small for 'Aylmer'. 'Bradley' has good resistance to lodging while it is fair for 'Goslin' and poor for 'Aylmer'. 'Bradley' is moderately resistant to crown rust (Puccinia coronata) and resistant to leaf blight (Septoria avenae f. sp. avenae) while 'Goslin' is susceptible to both and 'Aylmer' is susceptible to crown rust and moderately susceptible to leaf blight.
PLANT: covered type, spring type, erect juvenile growth habit, absent or very sparse pubescence on lower leaf sheath, absent or very sparse pubescence on lower leaf blade, low frequency of recurved flag leaves, sparse pubescence of the stem above and below the upper culm node
LEAF: medium green, absent or very sparse pubescence of margin, medium glaucosity
PANICLE: equilateral orientation, medium density, semi-erect attitude of branches, more than a 45 degree angle between dominant side branch and rachis, few hairs or spines on lowest node

LEMMA: weak glaucosity, small extent of lateral overlap on palea, white colour at maturity, absent or very sparse pubescence on lateral and dorsal surface, absent to weak tendency to be awned
SPIKELET: semi-abscission separation, semi-erect attitude, 2-3 grains
RACHILLA: short length between primary and secondary floret, absent or very short grooves, sparse pubescence
KERNEL: short basal hairs, cream colour
SCUTELLUM: pointed, medium sized
GROAT: medium pubescence
AGRONOMICS: good lodging resistance, 16% protein content, 7.8% lipid content
DISEASE REACTION: moderately resistant to Crown rust (Puccinia coronata), resistant to Leaf blight (Septoria avenae f. sp. avenae)
Origin & Breeding History: 'Bradley' (experimental designation OA1176-1) is a white-hulled covered oat variety developed using the modified Single Seed descent method from the final cross made in March of 2000. The pedigree is Ida / 06909-1-19, where 06909-1-19 is an Eastern Cereal & Oilseeds Research Centre breeding line from the cross of Aylmer / Goslin. The selection criteria included high yield, good groat percentage, disease resistance and good standability.
Tests & Trials: Trials were conducted during the 2010 and 2011 growing seasons at the Agriculture & Agri-Food Canada Eastern Cereal Oilseed Research Centre on the Central Experimental Farm, Ottawa, Ontario. Plots consisted of 4 rows with a row length of 3.6 meters and a row spacing of 23cm. There were 3 replicates.
