Origin & Breeding History: 'Dakota Crisp' originated from a cross between 'Yankee Chipper' and 'Norchip', made at North Dakota State University in 1984. 'Dakota Crisp' was selected in the field as a seedling in 1989 at Langdon, North Dakota, USA and tested under the pedigree number ND2470-27. It was derived from the hybridization of the two parents and a phenotypic recurrent selection technique was utilized in its development.

Tests & Trials: Trials for 'Dakota Crisp' were conducted in Drummond, New Brunswick in 2006. All entries were planted in single-row plots. Plots consisted of rows 22 metres long with 30 cm in row spacing and between row spacing of 91 cm. Measured characteristics were based on 10 measurements. Colour determinations were made using the 1986 RHS colour chart.
