Apple (Malus domestica Borkh.) trees can produce very large crops under optimal conditions. In New Zealand, record yields approaching 120 to 140 tha -1 fresh weight (18-20 tha -1 dry weight) have been sustained over several years (D.S. Tustin, personal communication). The high yields in New Zealand have been attributed to relatively cool but sunny growing conditions and a long postharvest season Thus, for a C 3 crop, apple has high potential productivity.
