I wonder if it would be a good thing to have a graft
compatability chart on our website for various fruits.
It seems like this could easily be constructed with
the help of our fruit consultants.
This chart would naturally include any compatiblility
issues such as long term over/under growth or long
term incompatibility.

Rob,
It's an idea, and perhaps one that merits undertaking, but I foresee some pitfalls along the way -
1.) "Mileage may vary" from one area of the country/world to another; for example, some of the OHxF clonal rootstocks that may work well in the PNW are worthless for growers in TX and the Deep South.
2.) What effect might latent viruses/mycoplasma, etc. - in either the scion or rootstock - have on intergeneric graft compatibilities? And how might we determine whether a particular scion or rootstock plant is infected?
3.) Some of this information is purely anecdotal, with no hard science behind it; it may be true, but not proven. Case in point - there's a hickory cultivar, "Cody Cox", which all my KY contacts swear is not compatible with pecan, and will only graft onto true hickories - but Gerald Gardner in MO, says it works just fine for him on pecan.
