Origin & Breeding History: 'Blueman' (experimental designation LRP 1424) originated from the cross Panache / Bluestar // 3005.10V conducted at a Norddeutsche Pflanzenzucht facility in France in 2007. One F9 line, trialed in Canada, was selected based on disease resisitance and agronomic characteristics. LRP 1424 was further evaluated in the 2015 and 2016 Western Canada Field Pea Cooperative Registration Trials.
Tests & Trials: The comparative tests and trials for 'Blueman' were conducted at DL Seeds Inc. in Morden, Manitoba, during the 2017 and 2018 growing seasons. The trials were established using a complete randomized block design consisting of 3 replications per variety. Each replicate consisted of 6 rows spaced 26 cm apart, with a row length of 4 metres. The measured characteristics were based on 100 measurements per variety per year. The mean differences were significant at the 5% confidence probability level based on a paired Student's t-test.
