Origin & Breeding History: 'PA1CN134' is a male sterile line which contains the Ms8 gene construct in the heterozygous state. It was produced in Saskatoon, Canada in 2008 and was selected in 2009 and 2010 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, oil content, fatty acid profile and glucosinolate content.

Tests & Trials: Trials conducted in the summers of 2012 and 2013 in Saskatoon, Saskatchewan were set up in a RCB Design with 3 replications per variety. Plots each year consisted of 3 rows 6 metres in length with a spacing of 25 cm between rows and 50 cm between plots. There were 30 measurements of the cotyledon, 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.
