Since you are new to trying your hand at hybridizing, my advice would be to just go for it, mark your crosses (I use colored paper clips) and record the crosses (Pod and Pollen parents) on paper or on your computer. And then wait and see what happens. If you get seeds ... and you likely will ... then grow those seeds out, after properly drying and chilling them, to see what you get. I can often tell if a cross I tried worked because I can see some of the parent traits in the new seedlings blooms. I also have started doing a visual pedigree chart of my favorites to see if any seedlings from my hybridizing efforts are picking up genetic traits from previous generations. It's a lot of fun and sometimes you can get something really worthwhile that you might want to name and register. I am just a hobby daylily lover, so I am not hybridizing to sell plants, but to create something desirable in my gardens. It's for personal reasons that I've been hybridizing for several years now. I find it absolutely fascinating and exciting to grow out daylily crosses!
