Its fruit is the largest of any species of Malus except domestica, up to 7 cm in diameter, equal in size to many modern apple cultivars. Unlike domesticated varieties, its leaves go red in autumn: 62% of the trees in the wild do this compared to only 2.8% of the regular apple plant or the 2,170 English cultivated varieties. [6]
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.
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.
Johann August Carl Sievers (1762–1795) was a Holy Roman Empire-born botanist who explored Central Asia, Siberia, and other Asian regions of the Russian Empire.Among the species first described by Sievers is Malus sieversii, the ancestor of the domesticated apple.
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 ]
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]
Malus sylvestris, the European crab apple, also known as the European wild apple or simply the crab apple, is a species of the genus Malus. Its scientific name means "forest apple", reflecting its habitat.
