Abstract

The resistance of 10 potato varieties to mechanical injury was tested. Large intra- and intervarietal variations were detected. The Dutch varieties, Record and Bintje, proved to be the most resistant followed by the Finnish varieties Jaakko and Pito. The amount of severe injuries increased with the age and the size of tubers. Among these varieties no correlation appeared between varietal starch content and injury resistance of tubers.
