2015 Progress Report -Evaluation of the Cornell-GenevaApple Rootstocks and Other Promising Apple Rootstocks

摘要

A number of new apple rootstocks from the Cornell/USDA apple rootstock breeding project, located at Geneva, NY which are resistant to the bacterial disease fire blight (Erwinia amylovora) are rapidly becoming available. These rootstocks are also dwarfing, resistant to apple replant disease and productive (Fazio, et al., 2014; Kviklys, et al., 2014; Robinson, et al., 2014a and b). In this project, which is supported by the IFTA Research Foundation, we are continuing to test the field performance, disease resistance and nursery performance of elite Geneva~R rootstocks and rootstocks from around the world.
