Apple Rootstock Info: V.1

The Vineland series of apple rootstocks originated as open-pollinated hybrids of ‘Kerr’ crabapples and M.9 rootstock and were selected at the Horticultural Experiment Station at Vineland, Ontario, Canada in 1958. According to information from the Ontario Ministry of Agriculture, Food and Rural Affairs, V.1 is in the M.26 size class, and yield and yield efficiency are usually greater than M.26. V.1 is cold hardy and somewhat resistant to fireblight. V.1 was included in the 1994 NC-140 dwarf apple rootstock trial at 25 locations in North America. After 10 years trees on V.1 were similar in size to M.26 EMLA and tree survival was excellent. Trees on V.1 produced few rootsuckers and burrknots and had cumulative yield and yield efficiency similar to M.26 EMLA.
