Primary ancestor of most domesticated apples

Malus sieversii is a wild apple native to the mountains of Central Asia in southern Kazakhstan and regarded as primary ancestor of most cultivars of the domesticated apple (Malus pumila). German nursery Pflanzmich.de. has in close collaboration with a plantsman imported a few of these wild apples from the Caucasus and started right away to propagate them. At the last month held German Trade fair IPM 2017 Pflanzmich.de could introduce the first trees to the market. Malus sieversii produces apples of 7 cm in diameter.
The nursery called this introduction ‘the IPM 2017 sensation’. Pflanzmich.de claims that these trees make a valuable contribution to the biodiversity in Germany. The availability is for the time being quite limited.
Unusual disease resistance

On the Malus sieversii Wikipedia-page the author mentions that this wild apple recently has been cultivated by the United States Agricultural Research Service, in hopes of finding genetic information of value in the breeding of the modern apple plant. “Some but not all of the resulting trees show unusual disease resistance. The variation in their response to disease on an individual basis is, itself, a sign of how much more genetically diverse they are than their domesticated descendants.”
