best red onions to beat white rot

ok, I know it's impossible to beat it, but I'd like to put up a good fight. going to plant them in the summer squash patch, which I don't think has had onions grown on it for a long time, and only plant red onions, as these seemed to withstand our rampant white rot this year better than the white onions did.

what red onions have others had success with in similar conditions? we like them for salads as well as cooking - perhaps I should try a couple of different varieties?

I got very good results from a red onion called Red Baron last year,  I've got a bag of Electric Autumn sowing sets from a newspaper offer to go in soon and will try Red Baron again in 2011.  Cheers,    Tony.

I have Electric as well.

I think it's more down to crop rotation than type of onion. My beds go in four pairs, like this:

2 x Potatoes
2 x Beans
2 x micscellaneous (no onions, not even spring o's)
then a pair: 1 x brassica and 1 x all onions.

Each pair is moved around the plot each year, and at year four I switch the brassica/onion pair over so, if you think it through, any one bed is visited by onions every eight years which should be enough to give a long enough break between onions to prevent white rot.

I'll let you know in eight years! Five to go.
