Selection/grow out process

[Nematode]

So last August I planted tps and harvested the bb's and marbles after the haulms died off.
The little taters survived in the vegetable crisper with minimal losses and are now sprouting in moist perlite.
What next?
Should I plant them as is or is there a benefit to sprout pulling?
Eventually I would like to select for favorable traits but just need to get some good eaters first.
What is a good spacing for plant out? I would prefer lots of smalls(golf ball or smaller) to a few large.


Seeds were:

Boyd dude
Magic dragons.

Thanks,
