Cass, your question: "Have any hybridizers reported virused seedlings
produced from virused
pollen and/or seed parent?" was answered in my post. Yes.
"Ping Lim, an All American Rose winning hybridizer, stated in
rec.gardens.roses that he has observed virused seedlings from virused
parents.
He is not the first hybridizer to report that some of his seedlings
were virused. Harvey Davidson reported in 1988 (Davidson, H., The American
Rose Magazine, volumn 29, page 16, (1988)) that some of his seedlings were
virused and that he had heard, in a recent lecture, Dr. Dennison Morey state
that rose mosaic can be transferred through pollen. Dr. Morey was at one
time the head of the breeding program for Jackson and Perkins."

I missed it. Thanks. And the information about UC's hedge trimming
experiment is discouraging as well. Then there are the reports about
heat-treated, so-called virus-cleaned, varieties showing symptons after
a number of years. Bad stuff. One wonders what percentage of garden
roses is clean!
