Background

Twinner is an early-maturing consumer variety with excellent consumption quality. Apart from the crossing, this variety was developed entirely on the organic farm run by the te Winkel family. After experiencing Phytophthora problems in organic potato cultivation for a number of years, Wim te Winkel decided to lend a hand. Wim was able to connect quickly with Agrico Research because he sold all his potatoes through Agrico.

The cross that produced the Twinner variety was between seedling MA 98-0032 (from Mansholt) and seedling AR 00-87-22 (from Agrico Research). There are a couple of well-known varieties among Twinner’s ancestors – Marabel and Sirco, both Mansholt varieties. A resistance gene against Phytophthora has been crossed into the parent sourced from Agrico Research.

Each seedling bred at Agrico is assigned a two-letter code followed by a year and an individual number. The abbreviation for te Winkel is TW, and when combined with the word “winner”, forms this variety’s name.
