Abstract

In spring, 1999, two trials of dwarf apple (Malus × domestica) rootstocks were established under the coordination of the NC-140 Technical Committee. One trial included 'Fuji' as the scion cultivar, and the other included 'McIntosh'. Rootstocks were CG.4013, CG.5179, Geneva® (G) 16N (liners from stoolbeds), G.16T (liners from stoolbeds derived from tissue cultured plants), G.41, G.202, M.9 NAKBT337, M.26 EMLA, Supporter 1, Supporter 2, and Supporter 3. The 'Fuji' trial was planted in Kentucky, Missouri, North Carolina, and Pennsylvania (Biglerville), with partial plantings in Pennsylvania (Rock Springs) and South Carolina. The 'McIntosh' trial was planted in Massachusetts, Michigan, Minnesota, Nova Scotia, New York (Williamson), and Vermont, with partial plantings in New York (Peru), Ontario, and Pennsylvania (Rock Springs). Trees were spaced 3x5m and trained as vertical axes. At the end of nine growing seasons (2007), trees on Supporter 1, 2, and 3 were similar in size to those on M.9 NAKBT337. Trees on G.41 were similar in size to those on M.9 NAKBT337 for 'Fuji' and to those on G.16 for 'McIntosh.' 'Fuji' trees on G.16, G.202, CG.5179 were similar to those on M.26 EMLA, and 'McIntosh' trees on G.202 were larger than those on M.26 EMLA, with those on G.16 smaller. Trees on CG.4013 were the largest in both trials. Cumulatively (2001-07) for both cultivars, the greatest yields were from trees on CG.4013. The lowest 'Fuji' yields were from trees on M.9 NAKBT337, Supporter 1, and Supporter 2. For 'McIntosh,' lowest cumulative yields were from trees on M.9 NAKBT337, G.16T, and Supporter 1. Cumulatively (2001-07), trees on Supporter 1, G.41, and M.9 NAKBT337 were among the most yield efficient, and those on CG.4013, M.26 EMLA, and G.202 were among the least yield efficient for both cultivars. On average over the fruiting life of this trial (2001-07), M.9 NAKBT337 resulted in the largest fruit, and Supporter 2 and 3 resulted in the smallest fruit.
