Variety Description

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

Summary: 'PB0CN216' has a longer cotyledon than 'PPS01-140 B-Line'. The leaf of 'PB0CN216' has more lobes than the reference varieties. 'PB0CN216' flowers later than 'PPS02-144 B-Line' and '5020'. The silique of 'PB0CN216' is longer than 'PPS01-140 B-Line'. 'PB0CN216' has a shorter beak than 'PPS02-144 B-Line' but longer than 'PPS01-140 B-Line'. The pedicel of 'PB0CN216' is longer than 'PPS01-140 B-Line'. 'PB0CN216' matures later than 'PPS02-144 B-Line' and '5020'. At maturity, the plant height of 'PB0CN216' is taller than 'PPS02-144 B-Line'. 'PB0CN216' has a higher oil content as a percentage in whole dried seed than 'PPS01-140 B-Line' and 'PPS02-144 B-Line'. The protein content as a percentage of dried oil free meal of 'PB0CN216' is lower than 'PPS02-144 B-Line'.

Description:

PLANT: open pollinated maintainer line for PA0CN116, spring type, medium to tall height at maturity

COTYLEDON: wide to very wide, long to very long

LEAF: light green, many to very many lobes, rounded margin, medium density of shallow to medium depth dentations, long, wide, long petiole

FLOWER PETAL: cream coloured, medium to long length, medium to wide width
SILIQUE: horizontal attitude, medium to long length, medium length beak, medium to long pedicel
SEED: black

AGRONOMIC CHARACTERISTICS: fair to good resistance to lodging

QUALITY CHARACTERISTICS: erucic acid is 0.01% of total fatty acids, oil content is 50.5% of whole dried seed, protein is 44.8% of dried oil free meal, very low glucosinolates (9.89 µmol/g)

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

Origin & Breeding History: 'PB0CN216' is the male fertile maintainer line of 'PA0CN116'. It is the non transgenic doubled haploid line 05-274-244 which was extracted in 2005 from the F1 generation of a cross made in 2004. 'PB0CN216' 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.
