It is common that when acquiring a package of seeds some acronym that in many occasions the consumer does not know its meaning. These acronyms refer to the type of seed according to its genetics, so depending on the type of seed in question, being of the same variety, we can expect different results.
The creation of the various types of seeds comes from the Mendel’s Laws, which promulgated the basic principles on the transmission of genetic inheritance, principles in force in the creation of cannabis seeds.
This principle has allowed seed banks to create an infinity of varieties accentuating desired features of each of the parents, which is why we can currently find different varieties on the market that adapt to the preferences of each one.
Identify this nomenclature to be able to choose the seeds that best suit us and knowing the possible results that we can obtain from each one is important when making our purchase.
The acronyms and types of seeds that we can find are:
Landraces o purebreds:
Are the pure varieties, indigenous to a given area and have never been crossed. They are part of any of the three great cannabis families: sativa, indica, and rudelaris. These varieties are characterized by being very homogeneous among them and having very similar characteristics in their growth and flowering patterns. All cannabis varieties come from one of them.
The name of IBL seeds comes from the English word InBred Line. These varieties come from crossing of plants with a very similar genotype and a long stabilization processTherefore, IBL seeds are highly stabilized plants, which have only been crossed with themselves, so they have very homogeneous traits.
F1 first generation subsidiary:
F1 seeds are the result of crossing of the pure varieties or distinct IBL. The offspring of these two parents are relatively homogeneous and have the so-called “hybrid vigor”, that is, the plants from F1 seeds will have the most desired characteristics of each of their parents and they will probably be more vigorous and productive than they.
F2 second generation subsidiary:
The F2 seeds are the result of crossing of two F1 varieties. The plants from these seeds are more heterogeneous since they have characteristics of the father, the mother and both simultaneously. These plants lose the hybrid vigor of the first generation.
When F2 individuals are crossed between them, F3 seeds are obtained and thus simultaneously.
BX seeds are the result of crossing an F1 specimen with one of its parents in order to accentuate some characteristics of one of the parents in the offspring. You can repeat the process and get BX1 and so on simultaneously. This method is frequently used to obtain seeds from a female clone from which the parents are not possessed.
S1 seeds are obtained by reverse the sex of a female plant and cross it with itself to get seeds. Plants from this type of seed will have traits very similar to those of the mother.
Most of the varieties that can be found in the market are polyhybrid, varieties from the crossing of two hybrids that are not stabilized so the offspring is very heterogeneous, although they are usually vigorous and good specimens can be found.
