I had thought that, too, but discovered it is not entirely true.
A case in point is 100 packages I purchased from New Zealand many years
ago and installed in three different yards. They were the prettiest bees
I ever had, and they were literally golden in colour. They produced
honey, but were noticeably vicious.
I wrapped them for winter, the same as all my yards, but by spring almost
none in those three yards were alive, whereas the other yards had normal
losses.
Of course, this does not prove the point conclusively, but other
experience over the years, plus comments by my friends who run thousands
of hives and thus have reasonable sample sizes when comparing stocks,
indicate there are large differences in winter hardiness between bees from
different sources. One example I recall was mention that Kona Italians
did not winter nearly as well as the Carniolans one particular year.
(That is particularly interesting since I understand they are open
mated).
Additionally, Africanized strains are reputed to not winter well in cold
climates, although Dewey Caron noted an apparent exception in Bolivia
(from a personal conversation). Strains recently mentioned here recently,
incorporating genes sent north by Kerr and distributed by USDA also had
wintering difficulties reportedly.
As for honey production, we bought stock for several years from a breeder
in the mountains of BC. His claim was that the stock was winter hardy,
and it was survival was fantastic, but the hives barely made a crop. They
managed to get built up and heavy for winter just in time, though. We
figured it out pretty quickly and replaced them with more productive bees
that wintered acceptably, but maybe not quite as well.
So, although I would say that, in general, there is some truth to the
statement, in particular cases there may be huge differences, and they are
well known in commercial circles.
Right Bob?
