DISEASE RESISTANCE: resistant to Blackleg (Leptosphaeria maculans asexual stage: Phoma lingam)
Origin & Breeding History: 'PA9CN102' is a male sterile line which contains the Ms8 gene construct in the heterozygous state. It was derived by backcrossing the doubled haploid line 07-340-008 to the male sterile line used as the source of the bar and barnase genes. The final backcross took place in 2008. 'PA9CN102' was selected in 2007 and 2008 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 were conducted in the summers of 2010 and 2011 in Saskatoon, Saskatchewan. Plots each year consisted of 3 rows with a row length of 6 metres and a row spacing of 50cm. In 2010, the trial was set up as 8 x 9 lattice with 3 replications. In 2011, the trial was set up as a RCB Design with 3 replications. There were 40 measurements of the cotyledon characteristics, 30 of the leaf, flower and plant height characteristics and 60 for the silique characteristics. Means are based on a two year average. Differences are significant at the 2% probability level based on LSD values.
