Origin & Breeding History: 'PPS03-149 B-Line' is a male fertile maintainer line of 'PPS03-149 A-Line'. It was derived as a doubled haploid line 98-55-256 which was extracted from the F1 generation in 1998, from a cross made in Canada in 1997 of 97CGH406 / 97CGH409. 'PPS03-149 B-Line' was selected in 1999, on the basis of height, vigour, maturity, blackleg resistance, oil content, fatty acid profile, and glucosinolate content.

Tests & Trials: Test and trials were conducted in Saskatoon, Saskatchewan during the summers of 2004 and 2005. Plots consisted of 3 rows that were spaced 50 cm apart with a row length of 6 meters. There were two replicates arranged in a RCB design.

Comparison tables for 'PPS03-149 B-line' with reference varieties 'PPS03-149 A-Line', '2733', 'Sprint', 'Westar' and 'Excel'

Means are based on a two year average of 60 plant parts for silique, 60 for leaf and petal characteristics, 60 for height and 40 cotyledon measurements. Differences are significant at the 2% probability level based on LSD values.
