Variety Description

Varieties used for comparison: 'PA0CN116', 'PPS01-140 A-Line' and '5440'

Summary: The cotyledon of 'PA3CN164' is smaller than that of '5440'. The leaf of 'PA3CN164' has a rounded margin with a medium number of lobes whereas the leaf of 'PA0CN116' has a sharp margin with many lobes. 'PA3CN164' has a narrower leaf and a shorter petiole than '5440'. 'PA3CN164' flowers later than '5440'. The petal of 'PA3CN164' is shorter and narrower than that of the reference varieties. The silique of 'PA3CN161' is shorter than that of the reference varieties. The silique beak of 'PA3CN161' is longer than that of 'PPS01-140 A-Line' whereas it is shorter than that of 'PA0CN116' and '5440'. The pedicel of 'PA3CN164' is shorter than that of '5440'. At maturity, the plant of 'PA3CN164' is taller than that of '5440'. 'PA3CN164' is later maturing than 'PPS01-140 A-Line' and '5440'.

Origin & Breeding History: 'PA3CN164' is a male sterile line which contains the Ms8 gene construct in the heterozygous state. It was derived by backcrossing a doubled haploid line to a male sterile line used as the source of the bar and barnase genes. The doubled haploid line was backcrossed in Saskatoon, Saskatchewan, Canada in 2008. The final backcross was produced in 2012. 'PA3CN164' was selected in 2011 and 2012 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, oil content, fatty acid profile and glucosinolate content.

Tests & Trials: The comparative trials conducted during the summers of 2013 and 2014 in Saskatoon, Saskatchewan were set up in a RCB Design with 3 replications per variety. Each year, the plots consisted of 3 rows that were 6 metres in length with a spacing of 25 cm between rows and 50 cm between plots. The measured characteristics were based on 30 measurements of the cotyledon, leaf, flower and plant height and 60 measurements of the silique. The means were based on a two year average. Mean differences were significant at the 2% probability level based on LSD values.
