the same terminology referring to filial generations of that line applies.

This is definitely not a new topic. I’ll continue to use F1, F2, etc. in the same way that everyone else does as you describe but I don’t think my original post was inaccurate.

Cannabis crosses are not F1s, so says science!

[image] Phylos Bioscience: Currently the way the cannabis industry uses the term F1 hybrid is wrong. An F1 hybrid (or filial 1 hybrid) is the first filial generation of offspring of distinctly different parental inbred types. Cross-pollination involving two true-breeding, or homozygous, parents, result in an F1 generation that are homozygous and consistent in seed form. There are very few, if any, true F1 hybrids in cannabis because every modern variety is heterozygous (highly variable). The P…

Does conventional breeding and filial notation apply to today's polyhybrids?

Watts defines an F1 as: the heterozygous offspring between two homozygous but unrelated seedlines. This makes sense and gives the F1 generation a unique combination of traits; uniform phenotype but not true breeding. This is important in the plant breeding world. This means that when a customer buys F1 seeds that they should expect uniform results. source- Watts. 1980. Flower & Vegetable Plant Breeding Grower Books, London
