I'm going back a lonnnnnnnng time and I haven't kept up, so forgive me.
Wasn't there some talk/experiment/hope etc. of breeding a rather more
ferocious strain of varroa resistant bees with our native bees to produce
the best of both worlds? Did that come to anything?

I think the best hope at the moment is a fungus that attacks the varroa
mite. I think the Africanised American Bees and the Brother Adam
experiments rather put people off importing foreign strains.
