I’ve finished harvesting all the potato plants that started out as true seeds in March. I started them in a 1020 tray of vermiculite and the pricked the healthy ones out into pots of soil and the. Planted into the field in June. I got a small number of whites and the variation in how much tuber was produced is quite stark.
Each of the green trays is from a single seed. The bits in the egg carton are from a mix when I just dumped the remnants of the vermiculite and unimpressive seedlings out and covered them in spoiled hay. The big bowl of spuds isn't part of this -- those are grown from TPS 4-5 years ago and vegetatively since.
If they taste nasty, they will go into the compost, otherwise I will grow some of all of them and judge them on their second year performance instead of on their first.
