Origin & Breeding History: 'PPS08-170 B-Line’ is the male fertile maintainer line of 'PPS08-170 A-Line’. It was produced in Canada in 2006 and 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 conducted in the summers of 2011 and 2012 in Saskatoon, Saskatchewan were set up in a RCB Design with 3 replications per variety. Plots each year consisted of 3 rows with a row length of 6 metres and a row spacing of 50 cm. There were 40 measurements of the cotyledon characteristics, 30 measurements of the leaf, flower and plant height characteristics and 60 measurements of the silique characteristics. Means are based on a two year average. Differences are significant at the 2% probability level based on LSD values.
