Malus floribunda, common name Japanese flowering crabapple, [1] [2] Japanese crab, [3] purple chokeberry, [2] or showy crabapple, [2] originates from Japan and East Asia. It may be a hybrid of M. toringo with M. baccata , in which case it would be written as Malus × floribunda .
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.
It has combined genetics of many selected breeds, including ancestry of McIntosh apple, Golden Delicious, Starking Delicious, Rome Beauty and the vf gene of Malus floribunda for scab resistance. [1] Fruit shape is usually somewhat elongated in shape, and lopsided in young trees. They are big in size, red flush over yellow, fading to orange. [1] [2]
It was a seedling produced in 1955 from pollinating 'Macoun' from 'Purdue 54-12' for the sake of acquiring Malus floribunda disease resistances. It was first released to the public in 1978. It was first released to the public in 1978.
Like other "PRI" apples it is of complex ancestry to ensure the utmost disease resistance and various cultivation advantages, along with a fresh vibrant flavor. Its ancestry includes the 'Rome Beauty', 'Melba', 'Golden Delicious' and 'Wealthy' apples, as well as the Malus floribunda crabapple for scab resistance. "PRI" is impressed in the ...
Anna was bred by Abba Stein at the Ein Shemer kibbutz in Israel, in order to achieve a Golden Delicious-like apple, that can be cultivated in nearly tropical areas.A regular apple needs between 500 – 1000 hours of chilling [2] (aka chill units [3]) in order to get in blossom, but Anna flourishes even with less than 300 hours, so it can be grown in warm climates.

Empire is a clonally propagated cultivar of apple derived from a seed grown in 1945 by Lester C. Anderson, a Cornell University fruit nutritionist who conducted open pollination research on his various orchards. [1]
Another type of applecrab breeding program stems from Malus niedzwetskyana, a red-fleshed crabapple, a few of which can still be found in Siberia and the Caucasus. It has been used by modern breeders to breed some red-leaved, red-flowered, and red-fruited domesticated apples and crabapples.
