Origin & Breeding History: 'Taurus' was derived from the cross 'McGregor' x 'Norlin' which was made in 1990 at the Cebeco Zaden breeding station in Lelystad, The Netherlands. In 1992 a single plant was selected, followed by line selection and replicated yield trials. The selection criteria were yield, oil content, resistance to fusarium and resistance to lodging.
Tests & Trials: Tests and trials for 'Taurus' were conducted at Namao, Alberta during 1999. The varieties were tested in a 4 replicate randomized complete block design. Each plot consisted of 4 rows, spaced at 28 cm, that were seeded to 6 metres and trimmed to 4 metres. Measured characteristics were based on 10 measurements. Results were supported by the official PBR technical examination report purchased from the United Kingdom.
