Background

Carolus is the first Agrico strain whose development goes back to crosses with the wild Solanum relatives. This variety is perfect for the organic market due to its resistance to Phytophthora.

This potato originates partly in South America and partly in the Netherlands and Germany. The first crossing was made with the wild South American variety in 1997. This relative was known to be resistant to Phytophthora. The breed was back-crossed a number of times with existing breeds, and this process was concluded by a crossing with Agria as the final mother variety due to its many positive traits. One of the father varieties during the process clearly left its mark in the form of a red eye.

The breed is named after the 16th century botanist Carolus Clusius. During the opening of the Pieperpad in 2009, visitors were asked to come up with an appropriate name, and they eagerly complied.

In addition to the organic market, this variety is also suitable for the fries industry, the table market and the overseas market.
