Recommended sources for high quality broccoli seeds for sprouting?

[TomandDon]

I am wondering if there is a recommended source for high-quality broccoli seeds for sprouting? In his research for the broccoli seed tea protocol Albert Wright has looked for a high quality source so participants in the research he is is doing have the same high quality seeds. I am assuming that if it makes a difference for the tea protocol, it would also make a difference for the sprout protocol as well.

This page has a link to the average seeds I use. They are Waltham 29. Not great but at least they know the cultiver. rbd-pd-protocols.blogspot.c...

It would be nice to find some better seeds. I figure I'll just eat more.

Thank you. By the way, how do we know what is a "better" seed or a "high quality" seed? Maybe the Waltham 29 seed is higher in sulfurophane than an un-named cultivar?

I saw a chart somewhere. Waltham 29 is pretty far down the list, but could not find the better cultivers. Most growers don't even know what their cultiver is.

Yes, this interesting. They say guaranteed levels, but don't say what those levels are. I have sent them an email asking for the guaranteed levels and will post here what their response is.
