I inherited a community plot this summer along with a sprinkling of second-season plants which were overlooked at harvest in the fall. I have one beet which is currently bolting (do you say bolting for beets?). I was planning on collecting the seeds, but then I read online that beets can wind pollinate with chard from up to 2 miles away!

I did a search to find out what possible chard-beet hybrid might result, but I couldn't find any descriptions. 

I understand that the results of cross-pollination are unpredictable, but what might I expect? Less tasty/sweet roots? Smaller roots? More chard like foliage? Is it just not worth taking the risk, and should I just buy more carefully cultivated seeds?
