What pears are quince compatible?

[Rahul1]

Interstem aka interstock Pear Grafting

This study demonstrates some pears effect on rootstock and scion. Note the Beurre Hardy though useful for compatability is not useful for dwarfing. This study is interesting American Pomological Society - Journal Volume 54 Number 4 A Multi-site Pear-interstem Trial in the Netherlands and Belgium

This was what had me worried. I specially ordered some Beurre Hardy scionwood to be used as interstem. Will have to try other cultivars I guess
