'Pintail' has a medium plant maturity whereas it is late for 'CDC Ptarmigan'. The kernel type is hard red for 'Pintail' whereas it is soft white for 'CDC Ptarmigan'. 'Pintail' has medium red kernel colour whereas they are white for 'CDC Ptarmigan'. The Stem Rust (Puccinia graminis f. sp. tritici) resistance of 'Pintail' is moderately resistant to moderately susceptible whereas it is susceptible for both 'CDC Ptarmigan' and 'Radiant'. 'Pintail' is moderately resistant to Stripe Rust (Puccinia striiformis) whereas 'CDC Ptarmigan' is susceptible.

Origin & Breeding History: 'Pintail' (experimental designations W460 and 00H050) is a double haploid line derived during 2001 from 98W049 in Lacombe, Alberta. 98W049 was created in 1998 and has the following pedigree: 93W022 / 'CDC KESTREL' // 'CDC CLAIR' / 3 / 'AC READYMADE' / 4 / 83W020007 / 5 / 'CDC HARRIER'. 83W020007 is the result of a cross between 78W005002 and 'Norstar'. Selection occurred in growth rooms and field plots in 2001 and 2002 based on the selection criteria of winter survival, plant type and disease resistance. Yield trials were conducted at various locations from 2003 to 2010. 'Pintail' was entered into the C level Coop Trials from 2008 to 2010.

Tests & Trials: Test and trials for 'Pintail' were conducted during the 2011 and 2012 growing seasons in Lacombe, Alberta. Plot size was 2.8 meters squared and consisted of 8 rows. The row length was 2.5 metres with 14 cm spacing between rows. There were 3 replicates arranged in a complete randomized block design. Measured characteristics were based on 20 measurements per variety per year.
