This is a question for the experienced hybridizers here.

In most cases, I loathe light midribs. (That is jmho and ymmv.) The few exceptions are when the bloom color itself is a pale yellow or polychrome or some other color where the light midrib does not stick out like a sore thumb, or when the midrib is pink. Very rarely there will be a daylily which has overall darker tepals and light midribs, where the midribs somehow just seem to "work". 'Rocket Booster' is one such example:

I have some (tet) seedlings which, alas, have light midribs, and the midribs on those seedlings don't, imho "work". The seedlings are all in the orange to red color range, and I would like to keep that color range, while getting rid of the contrasting light midrib.

Are these light midribs a recessive trait? Confused If so, then presumably outcrossing to something with "self" midribs should yield a few seedlings that don't have the light midrib.

If they are a dominant trait, then hoo boy... At least one parent had the light midribs; it is difficult to tell about the other, peach-colored, parent. Even if the other parent didn't have the light midribs, I could see that selfing or sibling crossing would yield me more of the same. (I don't really want to cross back to the questionable parent...)

Any ideas on how this trait works? Confused

Interesting question, Polymerous! Your Rocket Booster is a knock-out! I really like that one. Lovey dubby

Hmmmm, don't know the answer to that. I don't particularly pay much attention to midribs when I hybridize, so really don't know if it is recessive or not. I mainly hybridize for flower form and bud count.
