The BW resistance comes from PI 200815, a land-race discovered in Burma by USDA plant explorers back in the 1950s. The variety has been self-crossed 9 times now, so I'm sure it's stable. I get bacterial wilt every year without fail, and this variety keeps on going when non-resistant varieties have shriveled away to nothing. Contact me if you'd like a sample.
By the way, the commercial variety County Fair 87 Hybrid carries the same BW gene. It worked OK for me, although I prefer a slicer rather than a pickler. It's carried by a few seed companies, for instance, Gurney's, Jung, Vermont Bean. It was the subject of a Tomatoville thread a while ago.

Several other varieties mentioned in the above thread are bitter-free and won't attract cucumber beetles as much, but they don't have the actual BW gene for resistance and they will eventually get the disease, maybe a week or two later than bitter varieties. Believe me, I've tried them.

Fred I grew County Fair last year as well as another Diva which is supposed to be unattractive to cuke beetles. I guess Diva must genetically have that low cucurbitacin production. The rest were all OP varieties and none were attractive to the beetles the past two seasons where they were all inoculated with PGPR's.
Genetic resistance is great but you are limited to the varieties that you can grow if you want that resistance.
If the PGPR route shows consistent results in unattractiveness to cuke beetles and resistance to BW, then you could grow pretty much any variety without concern.
