In my opinion, if you only had a few seeds it would be from a nanner (male plant flower) that grew on the female due to stress. It might have not been visible stress to the plant but I would consider those seeds S1. In other words, it would be a seed formed thru rhodelization… spelling may not be correct . This was a technique learned and “perfected” by the breeder Soma. He used that technique to make fem seeds.
