Title: Field Performance of Malus Sargentiias a Rootstock for Four Commercial Apple Varieties
Authors: W.C. Olien, W.C. Stiles and R.C. McCrum
Sargent crab (Malus sargentii Rehd.), 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 60S of similar trees on standard seedling rootstock and yield efficiency was approximately 50$ greater on Sargent crab.
