Variety Description

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

Summary: 'PB9CN202' has a narrower cotyledon than 'PPS02-144 B-Line' and '5020'. 'PB9CN202' flowers later than 'PPS02-144 B-Line'. The silique of 'PB9CN202' is longer than 'PPS01-140 B-Line', 'PPS02-144 B-Line' and '5020'. 'PB9CN202' has a longer beak than 'PPS01-140 B-Line'. The pedicel of 'PB9CN202' is longer than 'PPS01-140 B-Line', 'PPS02-144 B-Line' and '5020'. 'PB9CN202' matures later than 'PPS02-144 B-Line' and '5020'. At maturity, the plant height of 'PB9CN202' is taller than 'PPS02-144 B-Line'. 'PB9CN202' has a lower oil content as a percentage in whole dried seed than '5020'.

DISEASE RESISTANCE: resistant to Blackleg (Leptosphaeria maculans asexual stage: Phoma lingam)

Origin & Breeding History: 'PB9CN202' is the male fertile maintainer line of 'PA9CN102'. It is the non transgenic doubled haploid line 07-340-008 which was extracted from the F1 generation of a cross made in 2004. 'PB9CN202' was selected in 2007 and 2008 on the basis of per se performance of height, vigour, maturity, blackleg resistance, 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.
