Origin & Breeding History: 'Medicine Hat' was developed by pedigree selection from the cross '98yt102', as the seed parent, and 'Buster', the pollen parent, made in January, 1999 at the Seminis Western Breeding Station in Filer, Idaho, USA. The F1 was planted out in the field that year and allowed to multiply. Early selections were made during the F2 for upright productive structure and desirable seed appearance. Bulking of successive generations along with additional selection for resistance to weathering when exposed to light and moisture, maturity, uniform ripening and yield potential were carried out. 'Medicine Hat' was tested as 'EX08550813'.

Tests & Trials: The tests and trials for 'Medicine Hat' were conducted at Parent Seeds, St. Joseph, Manitoba during the summers of 2007 and 2008. Trials consisted of 2 replicates per variety, consisting of 2 rows per replicate, measuring approximately 6.5 metres in length, with a row spacing of approximately 1 metre. Plants were spaced about 5 cm apart in the rows. Maturity data were extracted from the 2006 and 2007 Manitoba Dry Bean Cooperative Registration Trials.
