Origin & Breeding History: 'PPS08-165 B-line' is a male fertile maintainer line of 'PPS08-165 A-line'. 'PPS08-165 B-line' is a doubled haploid line that was produced in Canada in 2003. 'PPS08-165 B-line' was selected in 2005 and 2006 on the basis of height, vigour, maturity, blackleg resistance, oil content, fatty acid profile and glucosinolate content.

Tests & Trials: Trials were conducted during the summers of 2008 and 2009 in Saskatoon, Saskatchewan. Plots consisted of 3 rows with a row length of 6 meters and a row spacing of 50 cm. There were 3 replicates arranged in a RCB design.

Comparison tables for 'PPS08-165 B-Line' with reference varieties 'PPS01-140 B-Line', 'PPS02-144 B-Line' and '5020'

Means are based on a two year average of 40 measurements for cotyledon characteristics, 30 for plant height and 60 plant parts for leaf, petiole, flower petal, silique, beak and pedicel characteristics. Differences are significant at the 2% probability level based on LSD values.
