The flags, which you see in the Pumpkin Workshop picture, are used to mark hand pollinated fruits on the field. We also use onion bags to protect hand pollinated fruits from being eaten by small animals.
Aneta is removing squash seeds from marked fruits, and will label them and save them for next year. They will be planted and tested, and this is how new varieties spring into being.
We also have a pepper breeding program.
We also breed other vegetables.
