QUALITY CHARACTERISTICS: erucic acid is 0.03% of total fatty acids, oil content is 45.5% of whole dried seed, protein is 48.6% of dried oil free meal, low glucosinolates (10.4 µmol/g)
DISEASE RESISTANCE: resistant to Blackleg (Leptosphaeria maculans asexual stage: Phoma lingam)

Origin & Breeding History: 'PB1CN229’ is the male fertile maintainer line of 'PA1CN129’. 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.
