F1 Species x Advanced Phenotype Seedlings

F1 Species x Advanced Phenotype Seedlings

This part of my initial testing was important to me to see what was possible by crossing modern types onto species. My guess was that the use of species with modern, advanced types could produce much more interesting results than the initial crossing of species x species that had been done to develop the domestic hybrid daylilies. Brian Mahieu had done this work previous to me, and so his results showed me I could expect good things. I just w3anted to go in some slightly different directions. In addition, I wanted to to focus on species that either hadn't been used in any registered cultivars, or that had only been used minimally. This work was interesting in-and-of itself, but it was a precursor to the work I wanted to do with tetraploids.

This seedlings is very fascinating. One of many I raised from this cross, this one has been my very favorite and I think this is a quite modern look for an F1 species outcross.

This cross of H. vespertina and Substantial Evidence gave me many interesting seedling, with this one just knocking my socks off! It has been lovely and has a tall scape. I find the flower quite modern and interesting.

Linda is an excellent old Stout cultivar that we have grown here on the farm for decades. I suspected that its peach color and wavey edge would blend well with modern pinks with high-ruffled edges. Here are some results that I think show the potential of Linda with these types. For more information on Linda, click here.

Frans Hals is one of my all-time favorite daylilies. We have grown it for decades and it has survived every indignity that I have thrown at it. To read more about the many hardships Frans Hals has endured here over the years, and more about the cultivar in general, click here. Like Linda, Frans Hals have a considerable amount of ruffle on the edge of the petals, and I suspected that would combine nicely with modern, ruffled types. You can see the results in the slide above.

Frans Hals combines well with many different forms and colors of daylilies, and can throw an amazing array of seedlings when combined with modern types. Most surprisingly is that Frans Hals can produce near white, cream and melon colored seedlings, as well as clean pink, lavender and purples on those melon base colors. As well, forms can range from narrow spiders to round and ruffled, trumpet shaped to flat formed flowers. It also passes its great branching, bud count, rust resistance, thrip resistance and general resilience.

This cross was made for improving plant traits on the color changing types. The slide above shows three examples of first generation seedlings from the cross.

Here is one example of the result from crossing two of the F1 Frans Hals x Pigment of Imagination seedlings shown above. This is the greenest daylily I have ever seen. It is also a color changer, ending up chartreuse with a green and peach-orange edge by the end of the day. WOW!

My introduction Mount Doom is the result of on old cultivar (Poinsettia - Stout - 1953) crossed to a modern cultivar (Way Up There - Huben - 2015) and shows the remarkable results that can be obtained by crossing old cultivars with modern cultivars. While many old cultivars were used in breeding in the past, they were not combined with the types of advanced and concentrated genetics that we have now. I advice people to experiment with old x modern! To read more about Mount Doom, click here.

On a whim, I crossed Frans Hals to Mount Doom. I am so glad I did! This cross showed that Frans Hals also produces the dark sepal backs that create the three-dimensional effect seen in Mount Doom. I am especially thrilled with the white ones with dark backs!

I am very happy with the results of test mating species and old cultivars with modern types. I have show to my satisfaction that it is a very worthy path to pursue, both to bring in new genes to the domestic hybrid daylily gene pool and to use tried-and-true cultivars that are as good today as they were decades ago when first introduced. What is most gratifying to me is the combination of interesting flower phenotypes with vigor and hardiness I have seen in so many of these seedling.
