DISEASE RESISTANCE: moderately resistant to Blackleg (Leptosphaeria maculans asexual stage: Phoma lingam)

Origin & Breeding History: 'PA1CN132’ is a male sterile line which contains the Ms8 gene construct in the heterozygous state. It was produced in Canada in 2007 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 height, vigour, maturity, black leg 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.
