Have had this tree c. 12 years now. Tree is likely over 20 years old & senescent on this rootstock. Moderately (or more) Fireblight susceptible. Great cider, and fresh eating apple. No modern market potential, except for cider in areas with low fireblight pressure.
Update - This tree was removed in 2009. When cut down the tree had approximately 30% dead tissue in trunk at about 1.75m height. This was likely fireblight spread into the trunk. I have grafted a replacement on Geneva 30 rootstock.
Biggest drawbacks to GG are biennialism, modest fruit size and moderate fireblight tolerance. Was a significant commercial variety in the eastern US prior to about 1960.
