Thank you. The larger, older climbers are from Nessie, my cross between Montecito (Brunonii and Gigantea) and Mlle Cecile Brunner, crossed with Annie Laurie McDowell, another of my roses. The results run from almost miniature, thornless, ever flowering plant that refuses to grow to cathedral eaters which have yet to flower. The younger seedlings from this year contain some Nessie genes but are also hybrids containing Lamarque, Secret Garden, George Washington Richardson (Mlle de Sombreuil), Florence Bowers Pink Tea and some others crossed with miniatures, floribundas and a few select HTs, among others. There are also a number of species crosses in that and the other two seedling tables, including Hugonis, Xanthina, Primula, Serafinii, Foliolosa, double R. Spithamea, Minutifolia, Stellata mirifica, Banksiae and Basye's Amphidiploid 86-3 (Banksiae X Laevigata) and R. X Actii (Wichurana X Hugonis). Those are definitely "what if?" type crosses.
Jin, I doubt you did anything "wrong" when you tried raising seeds, other than select a seed parent known to not germinate easily. I'm sure if you tried it again using a different seed parent your results would be much better. Seed raising is actually not time consuming at all, depending upon which parents you choose. Some types, such as Banksiae, are known to often require two (sometimes more) years to germinate, though I have had several from Banksiae lutescens germinate in as little as four months from planting. Many minis sprout very quickly. When I harvested the Nessie seeds, I anticipated them being large because the mother is large, bred from even larger types. When they came out the size of sesame seeds, I figured nothing would germinate. Wrong! They came up like Winter Rye! Even with house eaters, it is possible to raise small roses. There are several seedlings which have grown like oatmeal on a two year old and never flowered, while others are only a few inches tall and have flowered repeatedly, starting at only three or four months from planting.
If you honestly want to know what roses have proven themselves good seed parents, buy a premium membership from Help Me Find-Roses. It only costs $24 a year and supports a very worthy cause. That opens the door for you to be able to explore every parentage there which has any known information.
What's really fun is being able to not only see what is behind the rose you are considering, but what else each one has helped create. Just click on any of the named roses in the tree and it takes you to that rose's page where you can explore all the same information about each one to your heart's content. You will notice some are used extensively as both seed and pollen parents while others are almost to never used as one or the other. You can obtain results from using pollen from many while they won't set seed or what they set just doesn't germinate. It's a bear trying to get Autumn Damask to set seed at all here, and when it does, it doesn't germinate, but by digging into many flowers, you can harvest enough pollen to use on several seed parents. Those seeds usually germinate more easily. If it won't work in one direction, try it the other.
I envy your rain, though not to the extent to which you are getting to "enjoy" it. Geoff at Cool Roses told me he had battled rain for a month which had caused a lot of the virus indexed Fortuniana I sent him to rot. We don't need THAT much rain, but a couple of inches, gently spread out over several weeks would certainly be acceptable!
Wowza!! You have some gorgeous roses there, especially William R. Smith, Mons Tillier, and Bassoeus Tea!! 
And that is an exquisite bloom of Grey Pearl!!! 
swoon!!
Right now the blooms have a light pink cast to them.
