POROSHIRI

The Poroshiri potato is one of the developed varieties used by Calbee for its potato products. It has shallow eyes, making it easy to peel. The name "Poroshiri" comes from the Ainu language and means "big mountain." This variety is known for its suitability in snack production, particularly for potato chips, due to its favorable texture and processing qualities.

This variety has gained recognition in Japan for its stable yield, improved pest resistance, and suitability for large-scale chip manufacturing. The Poroshiri potato variety produces tubers with shallow eyes, making them easy to peel, and has a high dry matter content, which enhances its suitability for chip production. 

It demonstrates strong resistance to golden cyst nematodes and moderate resistance to common scab, reducing the need for chemical treatments. Agronomically, it offers stable yields, good storability, and low sugar accumulation, preventing excessive browning during frying. Additionally, this variety was specifically bred to perform well under Japanese growing conditions, ensuring consistent quality and efficient large-scale processing.
