DISEASE RESISTANCE: moderately resistant to Blackleg (Leptosphaeria maculans asexual stage: Phoma lingam)
Origin & Breeding History: 'PPS08-170 A-Line is a male sterile line which contains the Ms8 gene construct in the heterozygous state and the GT 73 gene in the homozygous state. It was produced in Canada in 2006 and was selected in 2006 on the basis of male sterility stability, expression of tolerance to glufosinate-ammonium herbicide, expression of tolerance to glyphosate herbicide and good combining ability with numerous restorer lines. Other selection parameters included 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.
