Northern Growers - Comparison of Onion Varieties

Does Dixondale rename their plants from the original seed provider- I couldn't match many of their catalog offerings with the trials below.

Onions size depends on day length for proper growth. This thread is for northern growers with summer daylight hours of 14 or more hours. Southern growers may want to start a different thread with appropriate university research for their area.

This onion trial spans several years:

A few common ones here:

Sweet comparison only. Short day in PA?

I hope this is helpful as personal accounts on onion growing and storage vary widely. I'm not buying new seed this year but I will buy plants if they are available locally. Please add any other growing and storage comparisons for long day onions to this thread.
