Iowa has an abundance of hardy and productive varieties of summer and fall apples, but there are really no satisfactory varieties of late keeping winter apples that can be grown in the northern part of the state. The varieties that are hardy are inferior in quality, size and productiveness. The hardy foreign varieties that have been introduced are of short season, and will not keep longer than the 1st of December. As a consequence of this condition, the people must either do without winter apples, buy eastern grown apples or depend upon keeping the apples that they can grow by cold storage. In order to determine the practicability of cold storage for. keeping fall and winter varieties of apples, an experiment was made last fall to determine the keeping qualities of standard varieties that are grown in the state.
