As frost injury in early autumn often is a limiting factor of yield, varieties with
vines surviving slight frost are of great vaiue.
In these trials plants were graded according to their amount of injury after the
first frost. The highest values given for the greatest frost resistance. Here again
Sequoia was among the 4 most frost resistant varieties.
Finally are mentioned a few quality potatoes selected from this material and the
varieties Sequoia and Kennebec recommended as an addition to Icelandic market
potatoes.
