Variety used for comparison: 'Capital'
Summary: The foliage and glumes of 'Dieter' are yellow green whereas they are medium green on 'Capital'. The panicle of 'Dieter' has medium density whereas it is dense on 'Capital'. The glume and lemma of 'Dieter' have weak glaucosity whereas it is medium on 'Capital'. The angle between the rachis and dominant side branch of the panicle of 'Dieter' is 30 to 45 degrees whereas it is less than 30 degrees on 'Capital'. The lower glume and kernel of 'Dieter' are longer than those of 'Capital'.
SEEDLING (5-9 tiller stage): semi-erect juvenile growth habit, very sparse pubescence of lower leaf sheath and absent to very sparse pubescence of blade
LEAF (at booting stage): yellow green, absent to very sparse pubescence of the margins, medium intensity of glaucosity, high frequency of plants with recurved flag leaves, ranging from absent to very sparse to very dense pubescence/hairiness above upper culm node and absent to very sparse to dense pubescence below upper culm node
PANICLE (just after heading): equilateral/symmertical orientation, medium density
PANICLE BRANCHES: semi-erect to horizontal attitude, 30 to 45 degree angle between the rachis and dominant side branch, few hairs or spines on lowest panicle node
SPIKELET: weak glaucosity of glumes, semi-abscission separation of spikelet with semi-nodding attitude
RACHILLA: medium length between primary and secondary florets, absent to very short grooves, sparse pubescence
LEMMA: weak glaucosity, small lateral overlap on palea, white at maturity, absent to very sparse pubescence on the lateral and dorsal surfaces, absent to very weak tendency to be awned
KERNEL (primary kernels from upper spikelets): hulled, no basal hairs, light brown, two grains per spikelet, pointed medium-sized scutellum, medium density of groat pubescence
AGRONOMIC CHARACTERISTICS: fair resistance to lodging and good resistance to shattering
Origin & Breeding History: 'Dieter' (experimental designation OA1063-8) arose from the cross Pc68/ 'Donegal'// 'Capital' made in 1997 at the Agriculture and Agri-Food Canada Eastern Cereal and Oilseed Research Centre in Ottawa, Ontario using a modified single seed descent method. F6 lines were grown in single rows in 2001 and screened for agronomic traits, diseases in the field and for groat content, groat oil and groat protein in the Near Infra-Red Analysis lab in Ottawa. F7 and F8 lines were evaluated for yield and comprehensive evaluation in the 'Home Test' and 'Preliminary Tests' at the Central Experimental Farm in Ottawa. Since 2004, registration tests were conducted at several locations across Ontario.
Tests & Trials: Tests and trials for 'Dieter' were conducted by Agriculture and Agri-Food Canada at the Eastern Cereal and Oilseed Research Centre, Ottawa, Ontario during the summers of 2008 and 2009. Plots consisted of 4 replicates/variety with 4 rows/replicate, 3.6 meters in length, spaced approximately 0.25 metres apart between replicates.
