DISEASE REACTION: resistant to Blackleg (Leptosphaeria maculans asexual stage: Phoma lingam) and Clubroot (Plasmodiophora brassicae)

Origin & Breeding History: 'PA7CN136' is a male sterile line which contains the Ms8 gene construct in the heterozygous state. The double haploid line was extracted in 2016 from a cross made at BASF Canada Inc. in Saskatoon, Saskatchewan, Canada in 2015. 'PA7CN136' was selected in 2017 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 vigour, maturity, blackleg resistance, clubroot tolerance, seed pod shattering resistance, oil content, fatty acid profile and glucosinolate content.

Tests & Trials: The comparative trials for 'PA7CN136' were conducted during the 2017 and 2018 growing seasons in Saskatoon, Saskatchewan. They 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.
