Dakota Diamond: A new, bright white skinned, chipping cultivar with exceptional yield and long term storage potential. DAKOTA Diamond, a new, medium-late maturing chipping cultivar, was released in 2005 by the North Dakota Agricultural Experiment Station. Dakota Diamond has bright white skin, white flesh, round tuber type, shallow eyes, and is suitable for chip processing from 7.2C. It resulted from a cross in 1994 of ND4103-2 x Dakota Pearl, and was evaluated as ND5822C-7. The single hill was selected in Langdon, ND in 1995; the selection was evaluated in North Dakota state-wide trials and across North America. Yield potential is exceptionally high, with total yield, US No. 1’s and percent US No. 1’s of Dakota Diamond exceeding those of Atlantic and Dakota Pearl at both irrigated and non-irrigated sites. Tuber size distribution is similar to slightly smaller than Atlantic if managed appropriately. Specific gravity is high, averaging 1.090 across irrigated and non-irrigated production sites. Strengths of Dakota Diamond include high yield potential, attractive uniform tubers, resistance to common scab, excellent chip quality from late storage, and moderate resistance to pink rot. Additionally, Dakota Diamond possesses some level of resistance to the Colorado potato beetle. Dakota Diamond is susceptible to foliar late blight and PVY, and expresses typical symptoms of bacterial ring rot. It is susceptible to hollow heart and producers should monitor and limit tuber size to 283g. Dakota Diamond was included in the North Central Potato Variety Trial in 2002 and 2003 and in the Snack Food Association/US Potato Board Trial in 2003 to 2005.
