Conference pear fertilizing other pear tree

[Veggielot]

I have a pear tree already and was going to get a second. I want to get a conference pear, which I know is self fertile, but will it fertilise my other pear tree.

I googled 'pear tree fertilisation' and found this for you...so it depends on which other pear you have

Pear Tree Pollination Table

[FB.]

It depends which mystery "other" pear variety you have.

Any pear varieties which are related have a high chance of partial or even complete incompatibility (since incompatibility is intended to reduce inbreeding). Triploid varieties are not particularly good pollinators of any variety - related or not - because they don't produce much viable pollen.

Ah slight problem I don't know what type mine is. I guess I will have to wait and see when it flowers.
