Description
Alnarp 2
 
Introduced by the Alnarp Fruit Tree Station, in Alnarp, in southern Sweden in 1944. Alnarp 2 was selected in 1920 from a group of mixed Doucin (dwarf) trees and it was brought to the US in 1949. This clonal rootstock propagates easily in the stool bed and produces a free-standing semi-vigorous tree 85 to 90% the size of seedling. Alnarp 2 is very cold tolerant and has been used as an understock for interstem trees in cold climates. It is susceptible to fireblight, wooly apple aphid and collar rot. Alnarp 2 has not been widely tested in the U.S., and a report from Canada indicates that Alnarp 2 is hardy, precocious and sensitive to magnesium deficiency.
