Origin & Breeding History: 'Stampede', tested as ND020351, is a selection from the cross 94-029-01-01 / BDM-RMR-14. The final cross took place in the fall of 1998 in a greenhouse in Fargo, North Dakota. The F1 population (99-182) was grown in an off-season nursery near Blenheim, New Zealand during the winter of 1999-2000. The F2 population was grown in a nursery near Hatton, North Dakota in 2000. Single plant selections were made in the F2 based on plant architecture, pod load, plant vigour, maturity and lack of foliar diseases. The F2:3 line (99-182-05) was grown in a row arrangement in an off-season nursery in Isabela, Puerto Rico during the winter of 2000-2001 and was further selected for vigour, productivity, lack of visible foliar pathogens and maturity. The row was harvested in bulk as F2:4 seed and was entered into a pinto preliminary yield test at Erie, Hatton and Johnstown, North Dakota in 2001. The F4:5 selection was designated ND020351 and grown in an off-season nursery near Isabella, Puerto Rico in the winter of 2001. Simultaneous evaluation for reaction to Bean Common Mosaic Virus and bean rust were made in a greenhouse in Fargo, North Dakota. Continued evaluation from 2002-2007 in advanced yield trials at multiple sites in North Dakota and other states verified agronomic performance.

Tests & Trials: The tests and trials for 'Stampede' were conducted at Morden, Manitoba during the summers of 2010 and 2011. Trials consisted of 3 replicates per variety, consisting of 4 rows per replicate, measuring approximately 5 metres in length, with a row spacing of approximately 60 cm. Plants were spaced about 5 cm apart in the rows. Height data was extracted from the 2010 and 2011 Manitoba Dry Bean Cooperative Registration Trials.
