Great thread to start Kim!
Archiving is a great idea, but I agree, that unless we get to the point where we can archive rose tissue in very small manageable chunks (like viral or bacterial cultures in liquid Nitrogen or similar - which I suspect will be affordable in the next 25 years or so) what we archive may not be anything more than history. I have a fairly extensive database on MS Excel that documents all of the last 14 years of my breeding since building the greenhouse. With a little bit of work, anyone would be able to trace ancestries to get to named varieties.
With limited real estate (we live on 1 acre) I have not been able to keep all of the roses that I would like and have just a “handful” of named roses (bred by others) that I still keep.
With regard to seedlings that I have kept - there are very few old ones. I bred roses for about 6 years before building the greenhouse. There are only 2 seedlings that remain from those years.
Even many of my “important” proprietary breeders have been let go over the years, to be replaced by some of their offspring.
Since having a greenhouse (this is the 14th year that we have planted in the greenhouse), I have code named my seedlings by “year planted in the greenhouse”, starting with “A” for the first year all the way to “N” for those planted this year. Looking at the parentage of the seeds that we just planted, by far, more recent seedlings dominate both as seed and pollen parents.
They are as follows by group:
Seed parents:
“F” year - 1 seedling as a seed parent.
“G” - 2
“H” - 1
“I” - 3
“J” - 6
“K” - 15
“L” - 16
“M” - 13
Only 3 Named varieties were used as seed parents, ‘Midnight Blue’, ‘Gemini’, and ‘Cal Poly’.
Pollen parents:
“F” - 1
“G” - 1
“H” - 1
“I” - 2
“J” - 2
“K” - 7
“L” - 19
“M” - 16
Additionally, I used 4 named varieties as pollen parents, ‘Cal Poly’, ‘Black Magic’, ‘Hot Cocoa’, and ‘Kardinal’, and the species R. minutifolia.
It can be seen that the “K” and “L” year seedlings predominated. I dabbled with the brand new “M” seedlings last year, but the volume with them is very low due to the immaturity of the plants. Many of the “M” seedlings that prove to have good germination will be used more extensively in the coming year.
I am describing this to explain how transient are most of my seed and pollen parents. As mentioned earlier, I have let go many of the seedlings upon which my current breeding stock was built. Many that I used this year, will not be used again, even though some of their seedlings may prove to be an important link to the future.
It’s interesting how important links to future generations may themselves not appear to have much to offer (and they don’t in and of themselves), however, that lucky seedling, coming from a lucky break, carries the work forward, while the “link” becomes lost. There are very few “lost” links that I regret losing because the important genetics can be found in their offspring.
For the thousands of seedlings that I have grown, there are very few still living that I would include in an archive. I am not trying to throw cold water on a good idea, however, I think that looking at breeding potential, a vast germplasm can be found in a relatively smaller number of individual seedlings if carefully selected.
Some thoughts on Mr. Ralph Moore’s roses:
There is a vast resource among his seedlings that have been preserved that may be flying away very quickly. I am fairly confident that he would want us to share with each other as much of his material that we can. Kim, even those roses that he asked you “not to let get away”, I think that he would want them shared. For those of us who knew him, he seemed especially interested the last few years to get some of his more important seedlings that hadn’t been fully explored spread around. Besides the “standing on the shoulders of those who went before us” quote that many of us heard Mr. Moore say, he often liked to quote, “the only things that last are what you give away”. I think that there is much wisdom in those words.
