Trace, I think in the past I had read about some seeds of thornless HL producing thorns, but without the statement that it wasn't very many and so I kind of wrote that off as a very useful option.
But, you've got me reading more about it and seeing that it is a dominant trait; so they've gotten it to where thorns don't show up often, but can't quite get rid of them entirely - sort of like how my wife and I "somehow" ended up with 2 blue-eyed kids when neither of us has blue eyes.
And now I'm getting more tempted to give these thornless honey locusts a shot...

I wonder if someone planting some of the thornless variety in an area with a lot of wild honey locust and letting it cross pollinate with them would have a significant impact through the transfer of that dominant thornless trait. Then, even though that next generation would only have a 50% chance of passing on the thornless gene, there would be quite a few more of them out there "trying" to pass it on - and if they pollinated with each other, they'd have a chance of creating offspring with only the dominant gene to pass on.
Gradually, though the thornless genes would still be out there, I imagine the thornlessness would begin to take over. And the more people planting the thornless variety, the faster it would happen.
