September 5, 2017, Netherlands – In a hidden experimental field in Wageningen, the Netherlands, surrounded by tall maize plants, there are several smaller plots with potato plants.

In some of these plots there are only dead plants, in others the plants have been affected by late blight (Phytophthora infestans) to a greater or lesser extent, but there are also fields with only perfectly healthy potatoes.

The latter are the result of the latest crosses by the Wageningen company, Solynta. The breeders have succeeded, thanks to their revolutionary hybrid breeding technique, in making potato plants insusceptible to the dreaded potato disease.

A new way of potato breeding

Potatoes are generally clone-bred and grown vegetatively. A seed-potato is put in the ground, which produces some ten new potatoes. One of the disadvantages of this system is that the parent plant transmits diseases to the offspring. Also, making the crop resistant is a long process.

Solynta has therefore selected a whole new approach: the company developed hybrid breeding with elite parent-lines, which allow propagation with true seeds. READ MORE
