Apples requiring fewer chill hours, the cumulative hours between 32F and 45F during winter, are specifically bred or selected for regions with mild winters. These cultivars thrive where traditional apple varieties, needing extensive periods of cold dormancy, fail to produce consistently. ‘Anna’, ‘Dorsett Golden’, and ‘Ein Shemer’ are examples adapted to warmer climates, enabling successful apple cultivation in areas previously unsuitable for conventional apple growing.
The development and adoption of these cultivars offer several advantages. They allow fruit production in regions with short or mild winters, broadening the geographical range of apple cultivation and reducing reliance on imports. This expansion enhances local food security, strengthens regional economies, and provides consumers in warmer climates with access to locally grown apples. The historical context reveals a dedicated breeding effort to overcome limitations imposed by climate, ultimately leading to greater agricultural diversity.
