March 31, 2005 NDSU Releases Dakota Crisp, a New Chipping, Tablestock Potato Cultivar The North Dakota Agricultural Experiment Station announces the release of Dakota Crisp, a potato suitable for the chipping and table stock markets according to Al Schneiter, Chairman of the Department of Plant Sciences at NDSU. According to Susie Thompson, NDSU potato breeder, Dakota Crisp is the progeny of Yankee Clipper, released by the University of Maine, and Norchip, a NDSU release. The original cross was made in 1984. Dakota Crisp was selected at Langdon, North Dakota in 1989 and tested as ND2470-27. It has been evaluated for 11 years (1993-2004) in statewide trials. ND2470-27 was also tested for four years in the north-central potato variety trial and for three years in the Snack Food Association/U.S. Potato Board trials. Dakota Crisp has very good yield potential. In eight dryland yield trials at Park River, Hoople and Grand Forks between 1993 and 2000, Dakota Crisp out-yielded Dakota Pearl, a 1999 release from NDSU, by 20 hundredweight per acre, more than an 8 percent increase. In these same trials, the percentage of U.S. No. 1 tubers produced was 83 percent for Dakota Crisp and 74 percent for Dakota Pearl. More recently, in non-irrigated trials conducted at Hoople, N.D., and Barnesville, Minn., between 2001 and 2004, yields averaged 325 and 250 hundredweight per acre for Dakota Crisp and Dakota Pearl respectively. The percentage of U.S. No.1 tubers produced in the same trails were 84 percent for Dakota Crisp and 78 percent for Dakota Pearl. In irrigated trials conducted at Carrington, Dawson, Oakes, McCanna, Larimore and McLeod, N.D., and at Glyndon, Minn., between 1994 and 2000, average yield for Dakota Crisp was 406 hundredweight per acre compared with 335 hundredweight per acre for Dakota Pearl, a 71 hundredweight-per-acre advantage. The percentage U.S. No. 1 tubers produced was equal at 91 percent for Dakota Crisp and 90 percent Dakota Pearl. In irrigated trials conducted between 2001 and 2004 at Larimore, Dawson and Tappen, N.D. the average yield of Dakota Crisp was 293 hundredweight per acre, compared with 265 hundredweight per acre for Dakota Pearl, a 28 hundredweight-per-acre increase. The percentage of U.S. No. 1 tubers produced was 85 percent for Dakota Crisp and 78 percent for Dakota Pearl. The Dakota Crisp plant is vigorous, medium to dark green in color, and semierect to sprawling. The flower color is white. The pollen and berry production are low to moderate in the field. Tubers of Dakota Crisp are round, uniformly sized and smooth, with an eggshell skin color, white flesh and shallow eyes. The variety is medium in maturity and specific gravity. According to NDSU plant pathologists, it expresses typical symptoms of bacterial ring rot and potato virus Y and is susceptible to common scab, silver scurf and/or black dot, and foliar late blight. It is susceptible to major insect pests. Dakota Crisp has been tested and increased on several producer farms. Reports from the producers and industry have been very positive. The taste-test ratings of Dakota Crisp following boiling, baking and microwaving are comparable to other chipping varieties such as NorValley, Norchip, Atlantic and Snowden, according to Thompson. Seed of Dakota Crisp is available from certified seed growers in North Dakota and as minitubers from the North Dakota State Seed Department. The NDSU Research Foundation is seeking plant variety protection for Dakota Crisp. ### Source: Al
