Description:

'PPS01-180' is an open pollinated spring canola variety. The cotyledons are medium in width and short to medium in length. Leaf blades are medium green in colour with few lobes. The leaf margin is sharp with a medium density of dentations that are shallow to medium in depth. The leaves are medium in length with narrow to medium width and medium length petiole. The yellow flower petals are medium in length and width. The semi-erect to horizontal siliques are short in length and very narrow to narrow in width with a medium beak length and short pedicel length. The plants are medium in height at maturity. Seed colour is black. 'PPS01-180' has low erucic acid content and low glucosinolates. 'PPS01-180' is susceptible to glufosinate ammonium herbicides.

Origin & Breeding History: 'PPS01-180' was derived from a cross made in 1998 of PGS1827/97CGH403 using pedigree selection and inbreeding. 'PPS01-180' was selected in 1999 on the basis of height, vigor, maturity, blackleg resistance, oil content, fatty acid profile, and glucosinolate content. Breeder seed production commenced in 2001.

Tests & Trials: Tests and trials were conducted at the Bayer CropScience facility in Saskatoon, Saskatchewan in 2003, 2004. Plots consisted of 3 rows 6 meters in length with 50 cm row spacing. There were 2 replications laid out in a RCB design.
