Notes:
This information from a HMF user:
"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."
