Richard,

Below is what I learned from some rootstock experts at various universities when I was researching to write an article on cherries.  It's not definitive, as there is much more anecdotal information out there that is more valuable.  Was your heart attack figurative or actual?  If the later, please take care.

--------------------------------------------

Gisela Series:  From Germany, these rootstocks produce dwarf trees that fruit fast, within three years of planting. This precocious trait also encourages early flowering that kills emerging fruit buds in regions that have late frosts. Gisela is suitable for both sweet and sour cherries.  It is difficult to find, as there is a shortage of Gisela-grafted trees in retail markets. 

            Gisela 5.  Produces disease-resistant trees half the size of cherries grown on Mazzard rootstock.  If your soil has good moisture-holding capabilities, this is the best rootstock for backyard cherry trees, according to Lang.  

            Gisela 6.  Produces trees 65 to 95 percent the size of ones on Mazzard rootstock.  Lang says backyard growers should use this rootstock if their soil is sandy and dries out easily.

            Gisela 12.  A semi-dwarf rootstock that produces a tree 70 percent the size of the standard Mazzard.  Excellent disease resistance.  This is another rootstock that Lang recommends for sandy soil that dries fast.
