Variety Description

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

Summary: 'PA0CN122' has a smaller cotyledon than '5020'. The leaf of 'PA0CN122' is smaller than '5020'. 'PA0CN122' has a longer silique, beak and pedicel than 'PPS01-140 A-Line'. 'PA0CN122' matures later than 'PPS02-144 A-Line' and '5020'.

Description:

PLANT: male sterile inbred line, spring type, short to medium height at maturity

COTYLEDON: narrow to medium width, short to medium length

LEAF: light to medium green, medium number of lobes, sharp margin, medium to dense density of medium depth dentations, short to medium length, narrow to medium width, short to medium length petiole

FLOWER PETAL: yellow, medium length, medium width
SILIQUE: semi-erect to horizontal attitude, medium to long length, medium to long beak, medium to long pedicel
SEED: black

AGRONOMIC CHARACTERISTICS: fair resistance to lodging

QUALITY CHARACTERISTICS: erucic acid is 0.02% of total fatty acids, oil content is 48.6% of whole dried seed, protein is 45.9% of dried oil free meal, low glucosinolates (10.17 µmol/g)

DISEASE RESISTANCE: moderately resistant to Blackleg (Leptosphaeria maculans asexual stage: Phoma lingam) and resistant to Clubroot (Plasmodiophora brassicae)

Origin & Breeding History: 'PA0CN122' is a male sterile line which contains the Ms8 gene construct in the heterozygous state. It was derived by crossing a doubled haploid line 98-055-013, containing the bar and barnase genes to line 07NN001207, and using 98-055-013 as a recurring parent in a backcrossing scheme. The final backcross was made in 2009. 'PA0CN122' was selected in 2008 on the basis of male sterility stability, expression of tolerance to glufosinate-ammonium herbicide and good combining ability with numerous restorer lines. Other selection parameters included vigour, maturity, blackleg resistance, clubroot 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.
