F1 hybrids vs X Hybrids
Hello, I have heard about F1 hybrids in vegetable plants such as tomatoes. I have also heard about hybrids designated with an "X" between genus and specific epithet, such as Clematis X jackmanii. Are these the same kind of thing? Are F1 hybrids the result of crossing 2 different species, which I believe is what Clematis jackmanii is? Thank you
When two botanical species are cross bred with each other and the seedlings (= the cross itself) are described scientifically, then this is a called a hybrid species name. In a hybrid species name there is always a × mark between the genus name and the hybrid species name. The × is not written in italic and always in a small size. This × mark is written against the hybrid species name, so without a space.
Thank you very much, Eileen. Your response is very helpful
