Origin & Breeding History: 'PA3CN157' 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 line used as the source of the bar and barnase genes. The pure selected line was crossed in 2011 at Bayer CropScience in Saskatoon, Saskatchewan, Canada. 'PA3CN157' was selected in 2012 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, increased resistance to seed pod shattering, oil content, fatty acid profile and glucosinolate content.

Tests & Trials: The comparative trials conducted during the summers of 2014 and 2015 in Saskatoon, Saskatchewan 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.
