Variety Description

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

Summary: 'PPS08-171 B-Line' flowers later than 'PPS02-144 B-Line' and '5020'. The beak of 'PPS08-171 B-Line' is longer than 'PPS01-140 B-Line' but shorter than 'PPS02-144 B-Line'. 'PPS08-171 B-Line' has a lower oil content as a percentage in whole dried seed than '5020'. The protein content as a percentage of dried oil free meal of 'PPS08-171 B-Line' is higher than in '5020'.

Description:

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

COTYLEDON: medium to wide width, medium length

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

SILIQUE: semi-erect to horizontal attitude, short to medium length, medium length beak, short to medium length 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 47.2% of whole dried seed, protein is 47.6% of dried oil free meal, very low glucosinolates (9.59 µmol/g)

Origin & Breeding History: 'PPS08-171 B-Line' is the male fertile maintainer line of 'PPS08-171 A-Line'. It was derived by back crossing a doubled haploid line 98-50-104 to a male sterile line used as the source of the GT 73 genes in 2006. 'PPS08-171 B-Line' was selected in 2006 on the basis of per se performance of expression of tolerance to glyphosate herbicide, 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 2 x 11 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.
