Characteristics and performance of four new apple rootstock from the Cornell-USDA apple rootstock breeding program. Acta Horticulturae. 1058:651-656. Interpretive Summary: Technical Abstract: In 2010, the apple rootstock breeding program at Geneva, NY released 4 new apple rootstocks (Geneva® 210, Geneva® 214, Geneva® 890 and Geneva® 969). G.210 is a semi-dwarfing rootstock with vigor similar to M.7, with high productivity similar to M.9 and resistance to fire blight, phytophthora root rot, and woolly apple aphid. It has also shown tolerance to apple replant disease in field trials in New York and Washington. It is not free standing and requires a trellis for supporting the trees, which can lean under wet soils conditions. G.214 a fully dwarfing rootstock with vigor similar to M.9 with very high productivity and resistance to fire blight, phytophthora root rot, and woolly apple aphid. It is easy to propagate in stoolbeds has shown tolerance to apple replant disease in field trials in New York and Washington. It is not free standing and requires a trellis. G.890 is a semi-dwarf rootstock with vigor similar to MM.111. It has high productivity (similar to M.26) and resistance to fire blight, phytophthora root rot, and woolly apple aphid. It is easy to propagate in stoolbeds and is free standing in the orchard. G.969 is a semi-dwarfing rootstock with vigor similar to M.26 with very high productivity and resistance to fire blight, phytophthora root rot, and woolly apple aphid. It is easy to propagate in stoolbeds. It is free standing in the orchard. |
