Right now, our daylilies database has a pulldown field for "Rust Resistance" where you can choose "Shows Resistance" or "Shows Susceptibility".

chalyse has tree mailed me a spreadsheet containing detailed information that she has compiled on many hundred cultivars. The spreadsheet tells whether the cultivar has resistance or susceptibility and I will mark each cultivar accordingly.

Additionally, she has compiled a decimal system of rust resistance. Each cultivar is ranked from 1.0 to 5.0 to show resistance.

chalyse said:I'm assuming you mean one box made available in a cultivar's database page that can toggle from 1.0 to 5.0? If so, I have that data already, as aggregate averages in the scores (the source of what was used to name a cultivar Susceptible or Resistant). But, sent as decimal numbers, we could sort the database to return 1.0's ("vertically resistant"), 1.1-2.4 through each decimal setting ( for "horizontally tolerant" cultivars), as well as for 2.5-4.0 (researcher recommended range for preserving future-helpful rust-fighting genes that may be recessive or do not match current rust isolates), and even 4.1-5.0 for the small number of cultivars that only seem to survive rust with extreme chemical applications. Helpful on so many levels to a large spectrum of folks.

I'll send you the cultivar names now with their overall averaged (single) decimal-number scores, in case this all makes sense and is really do-able.

So I'll be adding this to the daylilies database soon.
