A hew potato variety 'Okhotsk Chip' was developed by Hokkaido Kitami Agricultural Experiment Station. It was selected from the progeny of a cross between 'Atlantic' and 'ND 860-2' in order to breed a good processing quality variety resistant to potato cyst nematode (Grobodera rostochiensis pathotype Ro1). The female parent 'Atlantic' is a potato chip variety with potato cyst nematode resistance and moderately resistant to common scab. The male parent 'ND860-2' is a breeding line for chip with low reducing sugar content. 'Okhotsk Chip' was recommended as a new early-maturing potato chip variety by Hokkaido government in 2004 and registered as 'Potato Norin No. 52' by the Ministry of Agriculture, Forestry and Fisheries of Japan in 2005. 'Okhotsk Chip' is an early maturing potato variety with round, white tuber and good chipping quality. The reducing sugar content of 'Okhotsk Chip' is lower than that of 'Toyoshiro' and chip color is good when processed immediately after harvest or after short-term storage. Glycoalkaloid content of 'Okhotsk Chip' tubers is lower than that of 'Toyoshiro'. 'Okhotsk Chip' is resistant to potato cyst nematode and moderately resistant to common scab.
