Project Summary

As evidenced in the previous work and performance of this project, the proposed and on-going research will enhance the economic viability of tree-fruit growers through improved selection of rootstocks that lead to greater production efficiency and improved fruit quality. Orchard labor and land will be utilized more efficiently, with fewer tree losses to pests and environmental stresses, leading to a faster and greater return on investment.

A compelling need exists to initiate new coordinated research on a large scale for temperate-zone fruit tree rootstocks as new genetic materials are developed or made available. Many new rootstocks will require a change in orchard cultural practices. Continued testing will provide a thorough evaluation of promising rootstocks, multiple genetic systems, and planting and training system efficiencies. This research project will continue to develop sound research-based recommendations for growers and nurseries that are based on extensive and collaborative multi-state work, providing an increased understanding of rootstock adaptability and performance.
