Variety Description

Varieties used for comparison: 'PPS98-274', 'PPS02-364' and '5030'

Summary: 'PR0CN436' has a longer petiole than 'PPS02-364'. The beak of 'PR0CN436' is shorter than 'PPS98-274' and 'PPS02-364'. 'PR0CN436' has a longer pedicel than 'PPS02-364'. 'PR0CN436' matures later than the reference varieties. At maturity, the plant height of 'PR0CN436' is taller than 'PPS02-364'. 'PR0CN436' has a higher oil content as a percentage in whole dried seed than 'PPS98-274'. The protein content as a percentage of dried oil free meal of 'PR0CN436' is lower than the reference varieties.

Description:

PLANT: male fertile restorer inbred line, spring type, medium to tall height at maturity

COTYLEDON: medium to wide width, medium to long length

LEAF: medium green, medium number of lobes, sharp margin, low to medium density of shallow to medium depth dentations, medium to long length, medium to wide width, long petiole

FLOWER PETAL: yellow, medium length, medium width
SILIQUE: horizontal attitude, long, short to medium length beak, medium to long 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 48.3% of whole dried seed, protein is 42.1% of dried oil free meal, very low glucosinolates (5.21 µmol/g)

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

Origin & Breeding History: 'PR0CN436' is a restorer line in the process of F1 hybrid production. It was derived as a doubled haploid line 07-356-123 containing the Rf3 gene construct in homozygous state. The cross was made in 2006 with the doubled haploid line being extracted in 2007. 'PR0CN436' was selected in 2008 on the basis of fertility restoration of numerous male sterile lines and expression of tolerance to glufosinate-ammonium herbicide. Other selection parameters included height, vigour, maturity, blackleg resistance, oil content, fatty acid profile, glucosinolate content and combining ability.

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.
