The apple [Malus domestica (Suckow) Borkh.] has been part of the human diet for thousands of years. The hundreds of varieties known today result from a long and complicated history where multiple wild species contributed to the fruit’s lineage as it traveled from Central Asia to China and Europe along the Silk Road, and later to North America. Apples rank among the top three fruits produced around the world, along with citrus fruits and banana. Worldwide, there are more than 7,500 known varieties in circulation, but it is estimated that only 40 cultivars account for the bulk of commercial production worldwide.
Although very few apple accessions are known to be from wild trees, scientists have become increasingly interested in the diversity of wild apples as a source for traits to improve commercial varieties, including resistance to pests, fungal infections and bacterial diseases, which are common problems in commercial apples.
