Origin & Breeding History: 'PPS02-182' was derived from cross PGS1805 / 97CGH403 using pedigree selection and inbreeding. 'PPS02-182' was selected in 2000 on the basis of per se performance, height, vigour, maturity, blackleg resistance, oil content, fatty acid profile, and glucosinolates content. Breeder seed production of 'PPS02-182' 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.
