Origin & Breeding History: 'PA5CN196' is a male sterile line which contains the Ms8 gene construct in the heterozygous state. It was derived by crossing a pure selected line to a male sterile donor line used as the source of the bar and barnase genes. The pure selected line was crossed in 2012 at BASF Canada Inc. in Saskatoon, Saskatchewan, Canada. 'PA5CN196' was selected in 2015 on the basis of male sterility stability, expression of tolerance to glufosinate-ammonium herbicide and good combining ability with numerous restorer lines. Other selection parameters included vigour, maturity, blackleg resistance, clubroot tolerance, improved resistance to seed pod shattering, oil content, fatty acid profile and glucosinolate content.

Tests & Trials: The comparative trials for 'PA5CN196' were conducted during the 2016 and 2017 growing seasons in Saskatoon, Saskatchewan. They were set up in a RCB Design with 3 replications per variety. Each year, the plots consisted of 3 rows that were 6 metres in length with a spacing of 25 cm between rows and 50 cm between plots. The measured characteristics were based on 30 measurements of the cotyledon, leaf, flower and plant height and 60 measurements of the silique. The means were based on a two year average. Mean differences were significant at the 2% probability level based on LSD values.
