Origin & Breeding History: 'Modoc' was selected at Klamath Falls, Oregon, in 1991 from a cross between 'ND1196-2R' and 'ND2225-1R'. The main goal of the cross was to obtain a variety with red skin and white flesh with an attractive appearance for the fresh market.
Tests & Trials: Trials for 'Modoc' were conducted in Drummond, New Brunswick in 2007. All entries were planted in single-row plots. Plots consisted of rows 22 metres long with 30 cm in row spacing between plants and spacing between rows of 91 cm. Measured characteristics were based on 10 measurements. Colour determinations were made using the 1986 RHS colour chart.
