Burpee replied again.
"Regarding this variety, our Endless Summer is not the same tomato used in the GMO study to which you refer.
The people who conducted this study likely never registered the name Endless Summer with the USDA as when we named our tomato and registered it with the USDA the name had not already been registered.
We would not have been able to use that name if it had. The tomato is completely unrelated to the GMO variety.
I checked a packet of Endless Summer tomato from our Walmart line and the lot number 16 is from Holland."
Customer service apparently gave up, because this was a reply from one of their horticultural experts.
So, there you have it.
