Summary: The cotyledon of 'PB1CN230' is shorter than that of 'PPS02-144 B-Line’. The leaf of 'PB1CN230' has a very low to low density of margin dentation with very shallow margins whereas 'PPS02-144 B-Line' and '5020’ have a medium density of margin dentation with medium depth margins. The leaf of 'PB1CN230' is longer than that of 'PPS02-144 A-Line' and 'PPS01-140 A-Line'. The leaf of 'PB1CN230' is narrower than that of '5020’. 'PB1CN230' has a longer petiole than the reference varieties. 'PB1CN230' begins flowering later than 'PPS02-144 B-Line' and '5020'. The petal of 'PB1CN230' is shorter and narrower than that of 'PPS02-144 B-Line' and '5020'. The silique of 'PB1CN230' is longer than that of 'PPS01-140 B-Line'. The beak of 'PB1CN230' is shorter than that of 'PPS02-144 B-Line' and '5020' and is longer than that of 'PPS01-140 B-Line'. The pedicel of 'PB1CN230' is longer than that of 'PPS01-140 B-Line' and '5020'. At maturity, the plant of 'PB1CN230' is taller than that of 'PPS02-144 B-Line' and '5020'.

AGRONOMIC CHARACTERISTICS: fair resistance to lodging
QUALITY CHARACTERISTICS: erucic acid is 0.03% of total fatty acids, oil content is 44.6% of whole dried seed, protein is 48.5% of dried oil free meal, low glucosinolates (12.4 µmol/g)
DISEASE RESISTANCE: moderately resistant to Blackleg (Leptosphaeria maculans asexual stage: Phoma lingam)

Origin & Breeding History: 'PB1CN230’ is the male fertile maintainer line of 'PA1CN130’. It is a non-transgenic line that was produced in Canada in 2009 and was selected in 2010 on the basis of per se performance of height, vigour, maturity, blackleg resistance, increased tolerance to seed pod shattering, oil content, fatty acid profile and glucosinolate content.

Tests & Trials: Trials conducted in the summers of 2011 and 2012 in Saskatoon, Saskatchewan were set up in a RCB Design with 3 replications per variety. Plots each year consisted of 3 rows with a row length of 6 metres and a row spacing of 50 cm. There were 40 measurements of the cotyledon characteristics, 30 measurements of the leaf, flower and plant height characteristics and 60 measurements of the silique characteristics. Means are based on a two year average. Differences are significant at the 2% probability level based on LSD values.
