Krymsk~(R)1 (VVA-1), a Dwarfing Rootstock Most Beneficial for Moderately Productive Plum Varieties

摘要

The plum rootstock Krymsk~(R)1 (WA-1) originates from the breeding programme of Dr. Gennady Eremin of the Krymsk breeding station in Russia. In 1994, the former fruitgrowing research station in Wilhelminadorp, the Netherlands, started the first trialin which this rootstock was compared to St. Julien A, the rootstock that until then was the standard one used for plums. This research was continued at PPO-Fruit in Randwijk, the Netherlands. In total, four varieties were trialed. In all cases the treeson Krymsk~(R)1 were compared to those on St. Julien A.
