Old Article on Japanese Iris Breeding

I recently came across an article in the February '83 issue of 
Horticulture Magazine titled "The Americanization of Japanese Iris" by Esther 
Mackintosh. The article chronicles the breeding efforts of William Ackerman and 
Margot Williams at the National Arboretum. Their early efforts (1959) were to 
extend individual flower longevity through progressive selection. Ackerman then 
turned to irradiation of hybrid seed (exposure to Cobalt 60 for 10,000 rads) to 
try and bring out recessive traits and introduce mutations. Finally they are 
embarking (1983) on attempts to cross a tetraploid (via cochicine) I. 
Pseudacorus and a tetraploid I. Kaempferi with hopes of introducing the color 
yellow with the japanese iris form.

Some 13 years has passed and I was curious if anyone had been succesfull 
with pseudacorus x kaempferi. Also have other hybridizers experimented with 
irradiation and what results did they get ?
