Origin & Breeding History: 'CDC Calvi' (experimental designation C08054) was selected from the cross of C02074 / C02034 made in 2003 at the University of Saskatchewan, Saskatoon, Saskatchewan using the approach method. Individual putative F1 plants were grown in the field in 2004 and were screened for brown seed colour. The F2 was grown in a growth chamber and the F3 generation was grown in the field in hills in 2005 with each hill planted to seed from a single F2 panicle. Single panicle selections from the 2005 hill nursery were planted in F4 hills in 2006. C08054 is derived from a bulked F4 panicle hill which was further tested in an F5 yield plot in 2007. From 2008 to 2012, C08054 was further evaluated in replicated yield tests and was grown in the Glabrous Canary Seed Cooperative Registration Tests from 2009 to 2012. C08054 was later named 'CDC Calvi'.

Tests & Trials: The test and trials for 'CDC Calvi' were conducted at the University of Saskatchewan during the summers of 2013 and 2015. There were 4 replicates arranged in an RCB Design. Plots consisted of 5 rows, 3.6 metres long with a row spacing of 23 cm. Measured characteristics were based on 20 measurements per variety per year. Mean differences were significant at the 5% confidence probability level based on a paired Student's t-test.
