Hemp Seeds: New F1 Hybrid Seeds
In the world of cannabis cultivation, there are many different terms. In this article, we will focus on one of them, F1 seeds. But what exactly are F1 cannabis hybrid seeds? How do they differ from other seeds? What are their advantages? You will find answers to all these and other questions in this article.
What are F1 Cannabis Hybrid Seeds?
F1 Cannabis Seeds represent the first generation of offspring from maternal varieties. This term is a genetic abbreviation of the word Filial 1, meaning "first children." These varieties are created by crossing two strong maternal lines. The resulting plants will have half the genes from each parent and will therefore closely resemble what the breeder wanted to obtain. In the cannabis industry, these varieties are still new, but they are expected to become a common part of cultivation in the coming years. The following three terms will help you understand the F1 concept.
Heterozygosity
Cannabis plants inherit genes from their maternal plants that determine their biological characteristics. Heterozygosity occurs when two different genes encode the same gene trait. For example, when a breeder crosses a purple cannabis plant with a green plant. The heterozygous offspring will inherit two different genes that determine color. One determines green color and the other purple color. These plants will therefore be unstable because some of them will have increased expression of the green gene, while others will have increased expression of the purple gene. The example is overly simplified, as plant color is also influenced by environmental factors, but it illustrates how such crossing works.
Homozygosity
Homozygosity describes the opposite phenomenon. Instead of inheriting two different genes that encode different traits, they inherit two genes that encode the same trait. If a breeder wants plants to have a purple color, they will be bred to inherit two genes, both of which encode high concentrations of anthocyanins. The result will be a more stable offspring because it will always have a purple color. By producing homozygous plants, breeders can achieve more uniform and stable crops, and thus more stable and desirable yields.
Hybrid Viability
Although inbreeding produces highly consistent and stable genetics, over time it can lead to inbreeding depression. This is a phenomenon that describes reduced viability, performance, and plant resistance. However, by crossing plants from two separate inbred lines, the offspring's genetics are renewed. This trait, called hybrid vigor (heterosis), is associated with increased production, higher disease resistance, and productivity of F1 hybrids.
