‘Golden Delicious’ and ‘Spartan’ apples from micropropagated trees and scions on seedling and M.7A rootstocks were evaluated for three seasons, at harvest, and after 120 days of storage (1°C) for quality. Ethylene production indicated that apples from the three rootstocks matured at approximately the same rate and could be harvested in the same time period. Apple quality was similar among the three types of rootstocks, and no particular quality advantage was apparent for firmness, soluble solids concentration, titratable acidity, carbohydrates or mineral content. Fruit from micropropagated ‘Golden Delicious’ trees were more yellow at harvest than fruit from other rootstocks, but this difference did not exist after storage.
