By the way, corn suffers from inbreeding depression which appears quickly if you save from too few plants. What 'too few' actually is seems open to debate but I've never seen a number less than 100. Don't despair though if you can only save from a few plants. Just go ahead and do it. You'll get reasonable crops for a few years. When you notice your crop getting weaker and production dropping you'll know it's time to buy fresh seed.
It is always doubtful and depends on the summer whether corn ripens in Finland, the growing season is so short. Anyway the crop is not likely to be very big so the temptation to just eat everything straight away is great But on the other hand, my aim is to grow food for nothing and imported corn seeds are expensive in those little sachets.
the answer to the inbreeding depression is simply to infuse new genetics every few generations..say..every second season, buy out a package or two of fresh seed, and mix it well with your existing seed before planting...seed exchanges are great for this...

Jeanine, apologies: this is a hijack
I'm pretty curious about this stuff...I wonder, if I plant potentially inbred seed from several sources, I suppose it's a bit of a 'lucky dip' that some will still have genetic strenth in an area where another is weakened?
I know it`s a little late, but you might want to take a look at these:
These are open pollinated and adapted to northern climates; that is very early maturing and cold resistant.
in case the links are not ok, because commercial the strain names are luther hill and yucon chief. both sweet corns.
