Variety Description

Varieties used for comparison: 'PPS01-140 B-Line', 'PPS02-144 B-Line' and '5020'

Summary: 'PB0CN215' has a narrower leaf than '5020'. 'PB0CN215' flowers later than 'PPS02-144 B-Line' and '5020'. The silique of 'PB0CN215' is shorter than 'PPS02-144 B-Line' and '5020'. 'PB0CN215' has a shorter beak than 'PPS02-144 B-Line' and '5020' but longer than 'PPS01-140 B-Line'. The pedicel of 'PB0CN215' is longer than 'PPS01-140 B-Line'. 'PB0CN215' matures later than 'PPS02-144 B-Line' and '5020'. At maturity, the plant height of 'PB0CN215' is taller than 'PPS02-144 B-Line'. 'PB0CN215' has a lower oil content as a percentage of the whole dried seed than the reference varieties.


PLANT: open pollinated maintainer line for PA0CN115, spring type, medium height at maturity

COTYLEDON: wide, long

LEAF: medium green, medium to many lobes, rounded margin, low density of shallow dentations, short to medium length, medium width, medium length petiole

FLOWER PETAL: yellow, medium length, medium width
SILIQUE: horizontal attitude, short to medium length, medium length beak, medium length pedicel
SEED: black

AGRONOMIC CHARACTERISTICS: fair to good resistance to lodging

QUALITY CHARACTERISTICS: erucic acid is 0.02% of total fatty acids, oil content is 43.2% of whole dried seed, protein is 45.9% of dried oil free meal, very low glucosinolates (9.57 µmol/g)

DISEASE RESISTANCE: resistant to Blackleg (Leptosphaeria maculans asexual stage: Phoma lingam) and resistant to White Mold (Sclerotinia sclerotiorum)

Origin & Breeding History: 'PB0CN215' is the male fertile maintainer line of 'PA0CN115'. It is the non transgenic doubled haploid line 05-274-187 which was extracted in 2005 from the F1 generation of a cross made in 2004. 'PB0CN215' was selected in 2008 and 2009 on the basis of per se performance of height, vigour, maturity, blackleg resistance, sclerotinia tolerance, oil content, fatty acid profile and glucosinolate content.

Tests & Trials: Trials were conducted in the summers of 2010 and 2011 in Saskatoon, Saskatchewan. Plots each year consisted of 3 rows with a row length of 6 metres and a row spacing of 50cm. In 2010, the trial was set up as 8 x 9 lattice with 3 replications. In 2011, the trial was set up as a RCB Design with 3 replications. There were 40 measurements of the cotyledon characteristics, 30 of the leaf, flower and plant height characteristics and 60 for the silique characteristics. Means are based on a two year average. Differences are significant at the 2% probability level based on LSD values.
