Summary: The objectives of this project were: 1. Compare the performance of the MSU cherry rootstocks (labeled as the Corette™ series) to currently available sweet cherry rootstocks using intensive cherry production systems. 2. Track the MSU rootstock performance in trials with PNW grower cooperators that are experimenting with a wider range of scions and orchard systems. 3. Collaborate with cooperating nurseries and the Clean Plant Center Northwest-Fruit Trees to ensure MSU cherry rootstocks are available as virus certified and genetically verified.
