Interpretive Summary:

Technical Abstract: Ten rootstock selections were tested for their ability to host woolly apple aphid aerial colonies. Differences among the various rootstocks were apparent within a few weeks of artificial infestation. After 4 wk, the susceptible rootstocks (including M.9, M.26, Bud 9, Bud 118, and seedlings from New York and Washington) were heavily infested. On MM.111 (whose resistance is derived from ‘Northern Spy’), colonies established successfully, but were small and poorly developed. The majority of the replicates of the Geneva ‘Robusta 5’ derived resistant rootstocks (G.202, G41, and 4210) were free from infestation; but some replicates had a few very small colonies.
