Origin & Breeding History: 'PPS07-162 B-line' is a male fertile maintainer line of 'PPS07-162 A-line'. 'PPS07-162 B-line' is a doubled haploid line that was produced in Canada in 2003. 'PPS07-162 B-line' was selected in 2004 and 2005 on the basis of 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 B-line' with reference varieties 'PPS02-144 B-line', 'PPS01-140 B-line' and '5020'
Means are based on a two year average of 20 plant parts for cotyledon characteristics, 60 leaf, plant parts for silique, beak and pedicel characteristics. Differences are significant at the 2% probability level based on LSD values.
