The late Dr. Robert Basye of Texas A & M University produced three amphidiploids of rose species. One is listed in HelpMeFind: http://www.helpmefind.com/plant/pl.php?n=11634
The other two are not listed. One of them is an amphidiploid of R. banksiae X R. laevigata that Dr. Basye called 86-3. He described it in the 1990 issue of the American Rose Annual. I have a photo of it that I will be glad to submit to HelpMeFind, if you will list it.
The other is an amphidiploid of R. rugosa rubra X R. wichurana called 86-7. I don't have any information on it, although there used to be a picture of its foliage on the Texas A & M web site.

Dear Jim,
I have now listed this two plants. You can submit your picture(s). Any detailed information on these roses would be precious.
Thank you for helping HMF.
Jocelen.

Here is some text that you could add to both 86-3 and 86-7. You can replace "this rose" with "86-3" or "86-7".
This rose is one of the amphidiploids produced by Dr. Robert Basye. An amphidiploid is the result of a cross between two different diploid roses, followed by doubling the chromosomes of the seedlings. This results in roses with 28 chromosomes, the same number as in most modern hybrid roses. Dr. Basye used colchicine to double the chromosomes. He did this as part of his program to breed blackspot resistant roses. By crossing diploid blackspot-resistant species, and doubling the resulting seedlings' chromosomes, he produced roses that could be crossed with modern hybrids to increase their blackspot resistance.
This rose is being used in the breeding program at Texas A&M University.

Wonderful, Jim.
What do you think HMF should call these roses - I mean, in addition to the seedling codes? Basye's Amphidiploid Banksiae? Basye's Seedling 86-3? or does it resemble Laevigata more? Bayse's Amphidiploid Wichurara?
For now, HMF has added Basye's Amphidiploid Seedling 86-3 and Basye's Amphidiploid Seedling 86-7.
Do these plants still exist?

I would call them 'Basye's 86-3' and 'Basye's 86-7'. Both are grown at Texas A&M University where they have been used in their breeding program. Dr. David Byrne is the head of the rose program at TAMU and he can no doubt tell you more about them. His email address is: d-byrne@tamu.edu
TAMU has a web page on Dr. Basye: http://aggie-horticulture.tamu.edu/rose/
TAMU used to have pages with information and photos of 86-3 and 86-7, but those pages have disappeared.
I grow 86-3. It is disease-free in northern California. The foliage is nearly identical to Fortuniana. The blooms are smaller than Fortuniana, and are single. I'll submit a photo that shows the foliage, but a photo of the blooms will have to wait until Spring.
