> If any of those crosses exhibited incredible fitness, they would already have displaced all but the most carefully managed bee stocks.

Following the pattern of corn hybrids and the Dadant hybrid bees, this type of hybrid has to be generated by the crossing of inbred lines. The offspring will not necessarily exhibit the characters of the parents.

My point was only that inbreeding leads to degeneration while carefully constructed hybrid lines can be far superior to the wild type. In the video, Brother Adam says: 

"There is no such thing as a perfect honeybee, it has to be created, bred, ... developed by the hand of man."  https://www.youtube.com/watch?v=V4j9tSneoL4
