Sargent crab ( Malus sargentiiRehd.), an apomictic crabapple, performed well as a rootstock for four virus-free commercial varieties: ‘McIntosh’, ‘Cortland’, ‘Delicious’, and ‘Golden Delicious’, in a trial planted in 1970 and evaluated over 13 years. The trees were free-standing and survival was 100% with no evidence of incompatibility. A weakness noted was the production of numerous root suckers. The effect of Sargent crab on fruit yield efficiency varied with variety. ‘Delicious’ on Sargent crab reached a size about 60% of similar trees on standard seedling rootstock and yield efficiency was approximately 50% greater on Sargent crab.
