I am often asked to provide prospective yields for fruit trees based on rootstock but generally reluctant to do so. So much depends not only rootstock, but also the variety [some are much more generous than others] locality, soil and the season. During bountiful good years with frostless springs the crop will be significantly greater than that during more difficult seasons.
However I realise it is useful to have some idea of what to expect so here is an educated guess of the type of yield you can obtain given average growing conditions. Just remember it can and will be more and less according to season and variety! All estimates per tree or per bush.
