You may remember my post of a few days back about the request on IdeaConnection for cucumber germplasm resistant to nematodes, Fusarium, CGMMV, downy mildew and cold, for a finder’s fee of $2,000. I did a few genebank database searches and didn’t get very far at the time, but a comment from the curator of the cucumber collection at CGN sent me back to their website because I had missed this crucial bit:
Searches can be made based on passport data and characterization / evaluation data or both. Only a selection of traits is on-line searchable, however all data are downloadable.
It turns out that the downloadable evaluation data for cucumber includes 3 experiments on downy mildew and one on Cucumber Green Mottle Mosaic Virus (CGMMV). So I got the Excel files and cross-searched them for material resistant to both diseases. The result is three accessions: CGN19618 (Taiwan), CGN21584 (India) and CGN22272 (Japan). The first two even have georeferences. The Japanese accession doesn’t, alas, but that would be my choice of the three for cold-hardiness. It’s a pickle obtained from the Know You Seed1 seed company. That’s three out of the five traits. I think that’s worth at least a thousand bucks, don’t you?
- The company is Taiwanese, but the passport data for the accession says “probably from Japan.” And the source is given as “Know You Seed, Japan.” Maybe the Japanese subsidiary? [↩]
