Investigating the effects of rootstocks on tree tolerance to biotic and abiotic stresses, tree growth, vigor, yield, and fruit quality helps tree fruit growers make informed decisions about the planting densities, production systems, and marketing schemes that suit their needs. Most of the known apple rootstocks were initially generated through breeding programs to provide particular attributes (e.g. resistance to fire blight, cold-hardiness and low vigor) to the grafted scion varieties. However, the production efficiency of any rootstock-scion combination can be influenced by factors other than the genetic makeup of the rootstock. These factors include, but are not limited to, soil type, weather conditions during dormant and growing seasons, and disease load that could differ among states and countries. Therefore, this publication is intended to show the performance of 'Honeycrisp' apple trees on 14 size-controlling rootstocks under Virginia State climatic conditions after seven years of planting.
