Abstract
A new pear tree named ‘Roksolana’ is disclosed. Fruit of ‘Roksolana’ is notable for its excellent eating quality-the fruit is firm and somewhat juicy, with high sugar and acid levels that give the fruit a complex and durable aroma and flavor. ‘Roksolana’ pears are harvested relatively late in the season, and have been found to store well over long periods. Once taken out of storage, ‘Roksolana’ pears are slow to mature and have a long shelf life.
