The D2212(S) variety originated in the 1960s/70s from a breeding program for apple rootstocks at the former Federal Research Institute in Ahrensburg. The aim was to breed homogeneous, disease-tolerant rootstocks that could be propagated generatively, by crossing the original species/varieties. The parent species/ varieties came from the original home of the apple. Hanna Schmidt, later one of the breeders of the Giessen breeding program, from which the cherry rootstock GiSelA® originates, was involved in the breeding.

 

D2212(S) is currently the only commercial rootstock with resistance to apple proliferation (Candidatus Phytoplasma mali). Apple proliferation is transmitted by Psylla and occurs worldwide. Infected trees on non-resistant rootstocks can no longer recover.

 

Malia®D2212(S) is indispensable as a rootstock for mothergardens, variety preservation and breeding quarters as well as for replantings.
