I'm so happy to see this thread resurrected, as I wasn't posting here when Patrick first started it in 2017. My breeding goals have morphed over the years. I started breeding in 2002, played mostly with species and diploid Asiatic hybrids for many years, with a smattering of diploid trumpets, aurelians and Blackhearts thrown in. But once I met Bob Griesbach in 2006 and visited him again most summers afterwards until his move to Florida in 2016, I was fully smitten with Orienpets and tetraploid trumpets/aurelians. Bob was of course very generous with seeds and pollen. I started slowly as I had so few fertile OTs to pollinate with the pollen I would bring back from Wisconsin. Oh the failed crosses on to 'tet Black Beauty', 'Scheherazade', 'Leslie Woodriff' and others over the years. But I slowly developed my own fertile hybrids using Bob's germplasm and selected commercial bulbs. The breakthrough was a 2006 cross of a light yellow Griesbach trumpet pollinated with a mix of OT pollen brought back from Bob's garden. These started blooming in 2009. One trumpet-shaped flower, nice yellow out and in with a good red throat caught my eye. It proved to be perfectly fertile both ways with either tet trumpets or with other Bob OTs. Its bloodline still runs though some of my hybrids. I've mentioned this story before, but will post a picture of the breakthrough hybrid again. It was instrumental in leading to my current goals:
1. Like Tracey, develop garden plants that I find aesthetically pleasing, with colorful flowers, strong stems, good fragrance where I can.
2. Line breed OTs, both white and yellow, with tricolored interiors. Improve their fertility. I've managed to broaden the interior color bands, sometimes push the bands further up the interior, and either diffuse or concentrate the pigmentation. Continue to reinforce and diversify these traits.
3. Cross OTs to tet trumpets and line breed. I don't mind diluting out the Oriental influence, as I pick up fertility along the way. But I do try to keep OT type interior colors in otherwise trumpet-heavy hybrids.
4. Line breed to reinforce tet trumpet traits developed by Bob, principally white flowers with picotee margins, and also white flowers with a tet White Henryi look, namely interior papillae and conspicuous yellow to orange throats.
5. Selectively combine above lines; for example, what will a white trumpet with really strong violet picotee x a tricolored OT yield? I've had success already in crossing tricolor OTs with tet White Henryi types resulting in a broader interior band of orange before the red kicks in.
6. 'Pink Jazz' x any and all of the above! Thank you Tracey and Patrick for the suggestion. 100s of bulbs now in ground from three years of crosses. 'Pink Jazz' readily sets seed with pollen from both my fertile OTs and tet trumpets. Now to bloom them to see what may result...
7. Per Patrick, cross the biggest OT x OT and biggest tet trumpet x tet trumpet. Side project so far.
8. Kick my diploid trumpet breeding back in to high gear. Love 'Tropical Isle' and its full-flowered, colorful offspring, though bud count is low and stems can be weak. I've been neglecting my diploid trumpets for several years, and have lost some good ones. So few commercial diploid trumpets exist any more, so I want to broaden my diploid germplasm again. Reinforce and mix up colors, violet, yellow, orange, green, you name it. Fragrance a priority.
9. Convert germplasm from # 8 to tets to then use on # 3 and #4. No progress yet, high priority. Imagine OTs with green or really dark violet exteriors.
10. Rest. Whew.
