Description:

'PPS01-140 B-line' is an inbred spring canola variety. The cotyledons are narrow to medium in width and short. Leaf blades are medium green in colour with few to medium number of lobes. The leaf margin is rounded with a very low to low density of dentations that are very shallow to shallow in depth. The leaves are medium to long in length with a medium width and a medium to long petiole. The yellow flower petals are medium in length and width. The horizontal siliques are short to medium in length and medium in width, with a short to medium beak length and medium pedicel length. The plants are tall. Seed colour is black. 'PPS01-140 B-line' has very low erucic acid content and very low glucosinolates. 'PPS01-140 B-line' is not resistant to glufosinate ammonium herbicides.

Origin & Breeding History: 'PPS01-140 B-line' is a male fertile maintainer line of 'PPS01-140 A-line. 'PPS01-140 B-line' is a doubled haploid line of 98-50-104. Doubled haploid line 98-50-104 was extracted from F1 generation derived from cross 97CGH400 / 97CGH403. 'PPS01-140 B-line' was selected in 1999 on the basis of per se performance, height, vigour, maturity, black leg resistance, oil content, fatty acid profile, and glucosinolates content. Breeder seed production commenced in the 2002 season.

Tests & Trials: Tests and trials were conducted at the Bayer CropScience facility in Saskatoon, Saskatchewan in 2002, 2003. Plots consisted of 3 rows 6 meters in length with 50 cm row spacing. There were 2 replications laid out in a RCB design.
