Well, I posted this under "site talk" but don't seem to be getting any replies. May be someone on the Iris list knows the answer. Just wondering why there is not a listing for ploidy in the Iris Database? I know it is included in the Daylily listings. I was adding Irises to my Flower 2013 software and noticed there is a ploidy menu there.

Most of the modern TBs & SDBs are 48 c. MTBs are diploid & more tets are coming. the hybridizers usually indicate. The old pallidas & other early historics are diploids (24). so it is not necessary to list for each plant. the change to tet for the larger TBs is not new so not listed.

Wow! Okay. I'll have to make a note of that. Really appreciate the response!!

This is exactly what I need to know. I plan to hybridize for hardiness and PBF, and concentrate on DIPLOIDS which have both in many cases. MTB's are dip AND tetraploid, and I need to know which are which. And when the change to tetraploid happened, I need to know which plants are which. It doesn't seem to be much to ask from a database that includes innumerable little details...

The subject of ploidy came up when the Iris Database was being revamped a couple of years ago. I don't remember exactly how the discussion went, but I suspect we didn't include a field for ploidy because it's something that is rarely included in AIS registrations. Most of the fields in the database mirror information from the registry. Additional fields were only included if we thought they would greatly enhance the search utility of the database.
