Breakthrough in Saline Potato Breeding: First Field Trials in Zeeland Show Promising Results

Rising sea levels and increasing soil salinity pose a major challenge for Dutch agriculture, particularly in the coastal provinces. Therefore, Dhanya International is fully committed to breeding salt-tolerant crops, or halophytes. Our latest project focuses on the potato, one of the most important food crops in the Netherlands.

In close collaboration with local farmers, we have established a special test field on slightly saline soil in the Zak van Zuid-Beveland. Here, we are testing different genetic lines of our in-house developed potato variant, 'Solanum tuberosum 'Zilte Vastheid''. The focus is not only on yield but also on disease resistance, drought tolerance, and of course, taste.

The initial results are encouraging. In addition to the higher yield, the plants also appear more robust against certain fungi that are common in moist, saline conditions. The coming months will be used to further analyze the data and select the most promising lines for larger-scale trials next season.

This research is part of our broader mission to make Dutch coastal agriculture future-proof. By developing crops that can grow with the changing conditions, we aim to secure food production while preserving the landscape.
