Dennis,
Japanese iris have a similar problem and I understand that hybridizers,
particularly in Japan are working on getting a yellow iris. John Coble has
slides of some of the attempts to get more yellow. I don't recall what
types of crosses they are doing in their attempts.
Bob Hollingworth has been working on siberians and expanding the signal
colour. I don't know if he is working at all with cultivars with yellow
signals. I believe he has some seedlings where the signal colour covers
most of the fall, leaving a rim of colour. There appears to be potential
for a yellow siberian with a rim of white.
Extrapolating from that, I would expect that you could carry out a similar
hybridizing program for other beardless iris. Go for it, Dennis.
