Pear rootstock Pyrodwarf^(S)

Vegetatively propagated Pyrus communis rootstock
Pyrodwarf^(S) is a Pyrus communis clone originating from the crossing "Gute Luise (Bonne Louise d'Avranches)" x "Old Home". It was developped at the research institute at Geisenheim and is marketed by the CDB.

Pyrodwarf^(S) is especially suited for sites, which cause problems to quince rootstocks.

Pyrodwarf^(S) grows less vigorous than pear seedling, similar to quince BA29 and quince A.

Concerning cropping potential and specific yields, Pyrodwarf^(S) does not equal quince C.  Early yields are achieved with weak growth on dry sites.
