Cannabis Plant Genetic Terminology: F1, F2, S2, IBL and BX

With the rising stardom of cannabis, people are now wholly invested in not just consuming but also growing the plant. Since all forms of cannabis are expensive, growing it might be a more cost-effective alternative. However, it may not be as simple as your backyard vegetable garden.

Fundamentals of Cannabis Breeding

The top-rated cannabis strains are earned by cross breeding high grade parent strains. These strains are commonly known as hybrids. Even so, strains obtained from areas where there are no strains present for breeding are known as purebreds or landraces. Popular landraces include Sativa, Indica and Ruderalis. Sativas are known to be highly effective as energizing strains. They operate better for people trying to indulge into a work ethic. On the other hand, Indicas act as deep relaxing agents to wash away an entire day’s fatigue.

Configuring Cannabis

Understanding the language associated with growing cannabis can be slightly puzzling, especially for newbies. Let’s decode the basics of cannabis breeding.

F1: First filial generation or more commonly known as F1 is the first offspring obtained from cross-breeding pure-bred parent strains.

F2: F2 stands for second filial generation. These strains are grown by cross-breeding F1 parent strains.

S2: S2 strains are obtained by “selfing”. Selfing (in biological terms) refers to the process where one strain plays the role of both the parent strains to bring forth a new strain. These are also known as feminized strains since the female gametes are forced to pollinate without male gametes.

IBL: True breed/Inbred line or IBL is a breeding method where breeders consistently breed identical strains for generations to stabilize the dominant traits.

BX: Commonly known as backcrossing, BX is a breeding procedure used to control the genetics of a strain. This way breeder’s are able to grow strains with their desired traits inherited from donor parent strains.
