Bradley

Oat

Variety Description

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.

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.
