Golden cyst nematodes have threatened the cultivation of ‘Toyoshiro’, a major potato variety used for chip processing in Japan. Common scab is a soilborne disease that occurs in potato fields worldwide. To solve these problems, we crossed two US varieties and selected a clone that showed a slightly higher marketable yield and a significantly higher yield rate, compared with ‘Toyoshiro’, and had good chip processing quality, extreme resistance to cyst nematodes, and moderately high resistance to common scab. This clone was named ‘Poroshiri’; it is the first variety released from the Calbee Potato breeding program.
