Varieties used for comparison: 'PPS02-364', 'PPS04-205 and '5440'
Summary: The cotyledon of 'PR7CN680' is shorter than that of 'PPS02-364' and narrower than that of 'PPS02-364' and '5440'. 'PR7CN680' has a shorter petiole than that of '5440'. The petal of 'PR7CN680' is longer than that of 'PPS04-205' and wider than that of 'PPS02-364'. The silique attitude of 'PR7CN680' is erect whereas the attitude is semi-erect to horizontal for 'PPS02-364' and 'PPS04-205' and horizontal for '5440'. The silique of 'PR7CN680' is longer than that of 'PPS04-205'. 'PR7CN680' has a shorter silique beak and a longer pedicel than that of 'PPS02-364' and 'PPS04-205'. 'PR7CN680' matures earlier than 'PPS04-205'. At maturity, the plant of 'PR7CN680' is taller than that of 'PPS02-364' and 'PPS04-205'. The seed coat of 'PR7CN680' is brown whereas it is black for the reference varieties.

Origin & Breeding History: 'PR7CN680' is a restorer line in the process of F1 hybrid production. It was derived as a double haploid line containing the Rf3 gene in a homozygous state. The cross and DH line extraction occurred at BASF Canada Inc. in Saskatoon, Saskatchewan, Canada in 2013. 'PR7CN680' was selected in 2017 on the basis of fertility restoration of numerous male sterile lines and expression of tolerance to glufosinate-ammonium herbicide. Other selection parameters included height, vigour, maturity, blackleg resistance, oil content, fatty acid profile, glucosinolate content, seed coat colour and combining ability.
Tests & Trials: The comparative trials for 'PR7CN680' 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.
