'PA0CN116' has a shorter beak than 'PPS02-144 A-Line' and '5020' but longer than 'PPS01-140 A-Line'. The pedicel of 'PA0CN116' is longer than 'PPS01-140 A-Line'. 'PA0CN116' matures later than 'PPS02-144 A-Line' and '5020'. The oil content as a percentage in whole dried seed of 'PA0CN116' is higher than 'PPS02-144 A-Line' and 'PPS01-140 A-Line'. 'PA0CN116' has lower protein content as a percentage of the dried oil free meal than 'PPS02-144 A-Line'.

Origin & Breeding History: 'PA0CN116' is a male sterile line which contains the Ms8 gene construct in the heterozygous state. It was derived by back crossing the doubled hapoid line 05-274-244 to a male sterile line used as the source of the bar and barnase genes. The final backcross was made in 2009. The doubled haploid line 05-274-244 was produced in 2005. 'PA0CN116' was selected in 2008 and 2009 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, blackleg resistance, sclerotinia tolerance, 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.
