FLOWER PETALS: yellow, short, narrow to medium width
SILIQUE: semi-erect to horizontal attitude, short, medium width, short to medium length beak, short pedicel
SEED: black
AGRONOMIC CHARACTERISTICS: fair to good resistance to lodging
QUALITY CHARACTERISTICS: erucic acid is 0.2% of total fatty acids, oil content is 46.8% of whole dried seed, protein is 27.1% of dried oil free meal, medium glucosinolates (17.6 µmol/g)
DISEASE RESISTANCE: moderately resistant to Blackleg (Leptosphaeria maculans asexual stage: Phoma lingam) and resistant to White Rust (Albugo candida, races 7a & 2v)
Origin & Breeding History: 'PPS07-162 A-line' is a male sterile inbred line used in F1 hybrid production, that contains the Ms8 gene construct in heterozygous state. It was selected in 2005 and 2006 on the basis of male sterility stability, expression of tolerance to glufosinate ammonium herbicide and good combining ability. Other selection criteria included height, vigour, maturity, blackleg resistance, oil content, fatty acid profile and glucosinolate content.
Tests & Trials: Tests and trials were conducted during the summers of 2007 and 2008 in Saskatoon, Saskatchewan. Plots consisted of 3 rows, with a row length of 6 metres and a row spacing of 40 cm. There were 2 replicates arranged in a RCB design.
Comparison tables for 'PPS07-162 A-line' with reference varieties 'PPS02-144 A-line', 'PPS01-140 A-line' and '5020'
Means are based on a two year average of 60 plant parts for leaf, petiole, silique, beak and pedicel characteristics. Differences are significant at the 2% probability level based on LSD values.
