Variety Description
Varieties used for comparison: 'Minot' and 'Reaper'
Summary: The leaves of '1918' have medium to many lobes whereas there are very few lobes on 'Reaper'. The leaf margin of '1918' is sharp whereas it is rounded on 'Minot' and undulating on 'Reaper'. The depth of margin indentation on '1918' is shallow to medium whereas it is medium to deep on 'Minot' and very shallow to shallow on 'Reaper'. The silique and silique pedicel of '1918' are longer than those of both reference varieties.

PLANT: open pollinated, spring seasonal type, medium height at maturity
COTYLEDON: medium to wide, medium length
LEAF: medium green, medium to many lobes, sharp margin, shallow to medium depth margin indentations, medium to long, medium width, long petiole
FLOWER PETALS: yellow, touching
SILIQUE: semi-erect attitude, long, medium width, medium to long beak, long pedicel
SEED: black
AGRONOMIC CHARACTERISTICS: good resistance to lodging, resistant to Glyphosate

Origin & Breeding History: '1918' (experimental designation 307236-C7) arose from the cross 'Prairie 719RR' x '9550' conducted in 2004 at the University of Alberta, Edmonton, Alberta. It was developed using the pedigree breeding method using selection criteria including vigour, flowering, plant height, maturity, seed yield, blackleg resistance and oil, protein, glucosinolate and saturated fatty acid contents.
Tests & Trials: The tests and trials for '1918' were conducted at the DL Seeds Sunvalley Research Farm in Morden, Manitoba during the summers of 2009 and 2010. Plots consisted of 3 replicates/variety arranged in a RCB design with each replicate consisting of 6 rows, measuring 6.0 metres in length with a row spacing of 17 centimeters. Plots were spaced approximately 0.3 meters apart. Measured characteristics were based on 40 measurements for cotyledon characteristics, 30 measurements for plant height and leaf characteristics and 60 measurements for silique, beak and pedicel characteristics.
