I’m just going off of what I’ve read and what has been said. I’ll be growing it myself to find out.
And if as it’s said, environmental factors play a role in male vs female flowers, I may even keep one Morris Burton potted in the driveway (also the greenhouse as applicable once built) to see if I can microclimate it to a “zone 7/8” tree to see if it throws any male flowers.
All speculation on my part at this time.

The Japanese are apparently interested in this as well.
