Malus sieversii has previously been identified as the main contributor to the genome of the cultivated apple (Malus domestica), on the basis of morphological, molecular, and historical evidence. [10] Fruit traits including crispness, more flavour intensity and fruit weight have undergone differential selection by humans to produce Malus ...
The wild apple is a deciduous small to medium-sized tree, but can also grow into a multi-stemmed bush. It can live 80–100 years and grow up to 14 metres (46 feet) tall with trunk diameters of usually 23–45 centimetres (9– 17 + 1 ⁄ 2 inches), although diameters exceeding 90 cm (35 in) have been recorded.

An apple is a round, edible fruit produced by an apple tree (Malus spp., among them the domestic or orchard apple; Malus domestica). Apple trees are cultivated worldwide and are the most widely grown species in the genus Malus. The tree originated in Central Asia, where its wild ancestor, Malus sieversii, is still found.
Malus (/ ˈ m eɪ l ə s / [3] or / ˈ m æ l ə s /) is a genus of about 32–57 species [4] of small deciduous trees or shrubs in the family Rosaceae, including the domesticated orchard apple, crab apples (sometimes known in North America as crabapples) and wild apples.
New species he described for the first time in the Flora Altaica include Malus sieversii (as Pyrus sieversii), the wild ancestor of the apple, and the Siberian Larch (Larix sibirica). The plant genera Ledebouria (in the Asparagus family, Asparagaceae), [2] and Ledebouriella (from the family Apiaceae) are named in his honor. [1] [3]
The genome sequence also provided proof that Malus sieversii was the wild ancestor of the domestic apple—an issue that had been long-debated in the scientific community. In 2016 a new and much higher quality whole genome sequence (WGS) for a double-haploid derivative of the Golden Delicious variety of apple was published. [ 2 ]
Lady Alice is a cultivar of domesticated apple that was discovered in 1979 at an orchard near Gleed, Washington, as a chance seedling, and is a registered trademark by the Rainier Fruit Company.
The MN55 cultivar apple developed by David Bedford, a senior researcher and research pomologist at the University of Minnesota's apple-breeding program, and James Luby, PhD, professor, Department of Horticultural Sciences, Horticultural Research Center, is a cross between Honeycrisp and MonArk (AA44), a non-patented apple variety grown in Arkansas.
