When I request seeds from a hybrid I do so with full knowledge that I am doing an experiment and I am looking forward to seeing the results. Who knows-something better than the parent could emerge.
As with most naturally pollinated plants, hybrid or otherwise, using any seeds not developed under controlled conditions can be unpredictable and none of us can tell if any measures were taken to insure the genetic integrity of non-hybrids grown alongside compatible relatives unless the trader specifically tells us. Usually the results are very good, but not always.
I believe most seed traders know that and have realistic expectations. Or do they?

I think the important thing is to make sure the person you are trading with knows that these are garden harvested from a hybrid. If they see a hybrid on your trade list, they might assume that you are offering extra commercial seeds. Lots of people don't mind trying garden harvest hybrid seeds, but for those that only want commercial hybrid seeds, they would want to know that information up front.

I always label my seeds and my exchange list with either OP (open pollinated); SP (self-pollinated) and C (Commercial). It makes it easier on your trade partner. Rule of thumb....If you want a perfect genetic copy of a plant then never use open pollinated seeds. Even though at times it's fun to see what grows.
