Out of 32 plants that I have had bloom so far this Spring (which is when I do the bloom/scape measuring and checking for rust):
8 plants show no rust whatsoever.
7 plants rate somewhere on a 2 scale (If I understand this rating correctly)
6 plants rate somewhere between a 2 and 3
10 plants rate between a 3 and 4
1 plant rates between a 4 and 5
But those numbers are only accurate if I understand the definition of each rating.
The seedlings that show the most resistance at a number 1 rating, have no sign of rust on them at all. None. There are rusty daylilies around them with some rusty leaves even touching their leaves. The seedlings are:
3 Laughing Clown x Zanti's Misfit (3 siblings) (CCC01, CCC05, and CCC08)
2 Laughing Clown x Instant Graffiti (2 siblings) (CCC03 and CCC06)
1 I am uncertain about the parentage (it looks like it might be a spider or UF type of daylily) (CCC17)
2 Galaxy Explosion x Lily Munster (2 siblings) (ZZZ37 and ZZZ38)
NOTE: All those above that are rated a 1 are spiders or look like spider form.
Rating #2:
1 Laughing Clown x Instant Graffiti (1 sibling) (CCC09)
1 unknown parentage I marked as CCC07 (a pretty pink bloom that is NOT a spider or UF)
1 unknown (CCC14) this is a large deep red bloom with yellow throat - very attractive bloom and foliage (not a spider form)
1 Francis of Assisi x unknown (CCC19)
1 unknown reddish-orange spider form (CCC21)
1 unknown orange w/yellow throat spider form (CCC22)
1 Galaxy Explosion x Lily Munster (ZZZ43)
Rating between a 2 and a 3:
1 Cherry Custard Cheesecake x Palace Garden Beauty (ZZZ31)
1 Laura Mast x Dragonfly Dawn (ZZZ73) This is the double bloom seedling
1 Through the Looking Glass x unknown (CCC04)
1 Stippled Statement x unknown (CCC11)
1 Bird Talk x unknown (CCC13)
1 Drink the Light x God Save the Queen (CCC15)
Rating between a 3 and 4:
1 Through the Looking Glass x unknown (CCC02)
1 unknown pink (CCC10)
1 Paper Butterfly registered daylily (CCC12)
1 Victorian Lace x unknown (CCC16)
1 Soft Summer Night (CCC18)
1 unknown red with yellow eye (CCC20)
1 Laura Mast x Dragonfly Dawn (ZZZ72)
1 Cedar Point (ZZZ61)
2 Dragonfly Dawn x Dragonfly Dawn (ZZZ66 and ZZZ67) Sad, but true!
Rating between a 4 and 5:
1 Hotter than the Fourth of July x Rorschach Test (ZZZ71) (This one looks like a rust bucket ... much to my dismay) It has a sibling right next to it that hasn't bloomed yet that also looks very rusty.
It's encouraging to see several that rate 1, and discouraging to see a possible 5. And of course, my favorite daylilies are at least a 3 rating or worse. (sigh)
I will be trying to cross the rust resistant daylilies with the pretty faces! I want the best of both, but we shall see which genes dominate in the breeding trials.
Something else to note: None of the spiders rated below a 2.
