How it began
The ancestor of the domestic apple is Malus sieversii, which grows wild in the Tian Shan mountains of southeastern Kazakhstan. The wild apple forests were first formally documented by the German botanist Johann August Carl Sievers (1762 to 1795). In 1929 the Russian scientist Nikolai Vavilov traveled through Central Asia, found the greatest diversity of apples near Almaty, and concluded that this was where the cultivated apple came from. Genetic markers and genome sequencing later supported his conclusion.
How it works
Domestication happened as people selected and moved desirable trees. According to a USDA plant physiologist quoted by the BBC, at some point seeds, trees or budwood from good trees were taken out of the Malus sieversii forests by humans and grown elsewhere. Wild Malus sieversii stands still occur across Central Asia, including Kazakhstan, Kyrgyzstan, Tajikistan, Uzbekistan, Turkmenistan and western China, with a notable concentration along the Trans-Ili Alatau range.
How it spread
Scientists believe seeds from the Tian Shan were first carried out of the region by birds and bears, long before people cultivated the fruit. By the time humans began to grow and trade apples, the wild species had already taken root as far away as Syria. The Silk Road then carried apples onward. In the mid-19th century settlers from the Voronezh province of Russia brought the Aport apple to the Alatau foothills, where it became a regional symbol.
What lasted
The apple became one of the most valued tree fruit crops in the world. A 2024 review in Horticulture Research describes Malus sieversii as the primary progenitor of domesticated apples and as a source of genetic diversity and resistance traits for breeding, at a time when a small number of commercial cultivars dominate production.
Where it stands today
The wild forests have shrunk. Soviet-era development destroyed large areas, and urban growth, pollution and deforestation continue to threaten them. Malus sieversii is listed as vulnerable on the IUCN Red List. Remaining stands are protected in areas such as Ile-Alatau National Park, and researchers call for conserving both the forests and their genetic resources. Almaty, whose name is often translated as father of apples, holds an apple festival.
