Konrad,

My two self fertile sweet cherry varieties, Vandalay and Black Gold, were grafted on G.5 rootstock. I don't know if the rootstock itself is self-fruitful or not.

This root stock has produced regular size cherries (I compare them to Bing from a supermarket.

My trees grow very well and send out many new shoots every year. I don't let them grow tall. It tolerates New England's wet spring well.

>>This root stock has produced regular size cherries (I compare them to Bing from a supermarket. Are you saying you had cherries, [not grafted] from the root stock G5?
Thanks!

Gisela 5 parentage comes from P. cerasus x P. canescens.*

I did a prunus rootstock patent search (patents in class plt/183) and I found six rootstocks that have (P. cerasus x P. canescens) in their parentage---one these could be Gilsela 5.

No, konrad. My cherries are from the grafted varieties. Sorry for the confusion.

Thank you Itheweatherman & mamuang!

Looks like not too much to be expected in a cherry.
