from potatoes from seed to seed potatoes

i prepared a couple more containers out back because i had some potatoes still form the basement seed potato project ( second photo ) laying about ( and i wanted late season spuds too ) but my main thrust was to plant the tubers i derived from plants grown from last season's potato seed ( third photo )to try and grow a second generation...it was also time to plant a few more onions ( purple ones today )...so that's what i did...if all the spuds in the fifth photo come up there will be some transplanting...however i am not convinced of the viability of some of the smaller tubers...as a corollary to this some of the potato seeds i planted last sunday have germinated ...i will be transplanting those to containers as well as soon as they are big enough..i am greedy for tubers from seed...so sue me.
