Abstract

A new and distinct strain of apple, designated ‘Walden’, originated as a whole tree mutation in a ‘Honeycrisp’ planting. The fruit are more attractively colored and glossier than parent tree fruit, which will greatly improve fresh fruit packout. Fruit color is solid scarlet red over 90 to 98 percent of the fruit surface compared to patchy red over a yellow-green background from parent trees. Color development is seven days earlier than ‘Honeycrisp’.
