Abstract : A 10-year study was conducted with 3 scion cultivars and 4 rootstocks. Eldon rootstocks significantly reduced scion diameter in all cultivars but its effects on the average number of fruits per tree were inconsistent. Eldon also produced significant reductions in tree height when cultivars Palmer and Irwin were used as scions. Significant reductions in tree height of cv. Edward were obtained with Julie rootstocks. Cv. Palmer produced the tallest trees and Irwin the smallest; the same pattern was observed for canopy volume. Eldon was most effective in reducing canopy volume for Palmer and Irwin but the greatest reduction in canopy volume for Edward was obtained on Julie. Irwin had the greatest yield efficiency regardless of rootstock; Palmer was the least efficient. Irwin was also superior in terms of total fruit weight per tree. There was no consistent influence of rootstock on total fruit weight per tree.
