Description Inventor: Guennadi Eremin, Krymsk (RU) at the Breeding Station in Krymsk, Russia. Sensitive to the pollen borne ILAR viruses. Very sensitive to PNRSV and PDV Could be a replacement of the Gisela® series. OLDEST TEST SITES IN THE US: Sweet cherries—2000 in California, Oregon, Washington and New York. Chilling Requirement: Appears to be higher than Mazzard seedling. This rootstock is widely used in commercial cherry orchards in the Pacific North West of the USA. It is a semi-vigorous rootstock, roughly similar or slighly more vigorous than Gisela 6. It is not as precocious or productive as the Gisela rootstocks, but fruit quality is good and it is arguably easier to manage the trees. Although developed specifically for cold-hardiness, this rootstock also performs well in hot climates and heavy soils. No support is necessary. Unlike many other modern cherry rootstocks it is not developed from Prunus cerasus.
