Planting seeds from hybrids will result in some plants that are like the parent plants and some that have a combination of traits. All will still be edible potatoes :) Save some of the ones you like to plant next time.

I don't agree on this one partly. They will be edible potatoes and all of that, yes, but the production would be very low and after three years, if you keep growing from the seeds, they will start to have normal production (meaning less production than the hybrids). So in conclusion, you need at least 3 years to have plants like the parent plants
