Hi all.
Would like to graft over a Pyrus calleryana (Chinese Pear) with species like Amelanchier alnifolia, Crataegus schraderiana/azarolus or Sorbus aucuparia/domestica.
Which of these will work?
Is there an interstem that could potentially make all these grafts compatible with Pyrus rootstock?

Thanks

I know many species within the subtribe Malinae can survive being grafted onto another tree, but they often do not flourish and would not be considered truly "compatible" in the broadest sense of the word. Heavy dwarfing is frequent. In general, if you graft a much slower growing species onto a species with a much higher rate of growth, there is a high chance of long-term graft incompatibility showing up after a few years.

Sorbus and Pyrus seems to be very compatible, and there do exist interspecies hybrids between some of the different genus you mentioned, though this often does not transfer over into graft compatibility.

There are certain apple and pear varieties that you will likely have more success with for graft compatibility.
