Origin & Breeding History: 'Rugby' (experimental designation 30608-A5) is the result of the cross '6.017.026' x 'PF1857/95RR' conducted in Hohenlieth, Germany in 2002. It was developed using the pedigree breeding method using the selection criteria including quality traits, Glyphosate tolerance, blackleg tolerance and agronomic characteristics.

Tests & Trials: The tests and trials for 'Rugby' were conducted at the DL Seeds Sunvalley Research Farm in Morden, Manitoba during the summers of 2009 and 2010. Plots consisted of 3 replicates/variety arranged in a RCB design with each replicate consisting of 6 rows, measuring 6.0 metres in length with a row spacing of 17 centimeters. Plots were spaced approximately 0.3 meters apart. Measured characteristics were based on 40 measurements for cotyledon characteristics, 30 measurements for plant height and leaf characteristics and 60 measurements for silique, beak and pedicel characteristics.
