Variety Description

Variety used for comparison: 'Triple Crown'

Summary: 'Domingo' has a semi-erect juvenile growth habit while it is erect in 'Triple Crown'. The leaf glaucosity of 'Domingo' is weaker at the booting stage than 'Triple Crown'. 'Domingo' has a higher frequency of recurved/drooping flag leaves than 'Triple Crown'. The plant height at maturity of 'Domingo' is slightly taller than 'Triple Crown'. 'Domingo' has a intermediate panicle orientation while it is equilateral in 'Triple Crown'


SEEDLING (5-9 tiller stage): semi-erect juvenile growth habit, absent to very sparse pubescence of lower leaf sheath and blade.

PLANT: medium to tall height, intermediate number of tillers, medium to late heading and maturity
STEM: absent to very sparse pubescence/hairiness above and below upper culm node, white straw, medium thickness

LEAF (at booting stage): absent to very sparse pubescence of the leaf margin, weak intensity of glaucosity, high frequency of plants with recurved/drooping flag leaves

PANICLE (just after heading): intermediate orientation, semi-erect to horizontal attitude of branches, pendulous attitude of spikelets, medium length
LEMMA: white colour at maturity, absent to very sparse pubescence on the lateral and dorsal surface, medium length
GLUME: weak to medium glaucosity at the green stage, mid-long
KERNEL (primary kernels from upper spikelets): white colour, medium width, medium length, medium groat pubescence

DISEASE RESISTANCE: moderately resistant to Black Loose Smut (Ustilago avena), Covered Smut (Ustilago kolleri) and Red Leaf Rust (BYDV), moderately susceptible to Stem Rust (Puccinia graminis f. sp. avenae) and Crown Rust (Puccinia coronata)

AGRONOMY: good shattering resistance, good drought tolerance, good lodging resistance
QUALITY: medium protein, medium oil content

Origin & Breeding History: 'Domingo' whose experimental designation is 'SW00448' was developed by Svalof Weibull AB, Svalov, Sweden. The variety originates from the cross SW 83-96 x SW 91-96, which took place in 1996. 'Triple Crown' is in the complex background of both parents. The breeding was a modified pedigreed method where a single plant was selected in the F4 generation. Early generation selection was made using straw stiffness and other agronomic characters with later selection for yield and grain quality being done.

Tests & Trials: Tests and trials were conducted during the summers of 2004 and 2006 in Aberdeen, Saskatchewan. Plots consisted of 8 rows with a row spacing of 15 cm and row length of 6 metres. There were 2 replicates arranged in a RCB design.
