F (filius) - F1, F2, F3 etc.

The branch generation is a term that, in its application, numerically designates and orders the different generations of descendants. The "F" in these generational designations stands for "filius," which means "son" in Latin.
The successive generations are listed accordingly (F1, F2, F3, etc.) to show the different stages of plant development and crossing.
These generations are important in plant breeding and genetics to understand how traits are inherited and to select plants with desirable characteristics for further cultivation or research.
In practice, the parents of the first generation of a cross are called the parental generation. The plants resulting from pollination now form the first branch generation, also called F1. If these descendants are now crossed with each other, one can only speak of the F2 or second branch generation. In addition to the selection of desired characteristics, this selection is always carried out under the premise of inbreeding, which can also have negative effects on the general health of individuals, not only in plants. A strong selection should therefore always be made as to which plants form the parents of the next generation and which plants are better disposed of.
