genes to enter the pool. This is called ‘Introgression’. During the
process of introgression many new traits will pop up in the population.
If the population is small equilibrium may be violated. By
chance alone certain members will be eliminated from the population.
We will find that the frequency of an allele will DRIFT towards higher
or lower values.
Non-random mating and Natural selection:
This suggests that something external may influence a
population to a stage where mating is not random. If some flowers
develop earlier than others then they will gather pollen earlier than the
rest. If some of the males release pollen earlier than others then the
mating is not random. Or maybe all males release their pollen earlier
resulting in some of the later flowering females ending up as a
sinsemilla crop. This means that these late flowering females will not
make their contribution to the gene pool. Again equilibrium will not be
With regards to natural selection the environment may cause
a problem with a section of plants. If this section does not survive then
they will not be able to make a contribution to the gene pool. If this is
the case and if selections are made so that other plants do not make a
contribution then we know that trait frequencies can be controlled to a
certain degree. And the ability to control the frequencies of a trait is
what BREEDING IS ALL ABOUT.
HOWTO TRUE BREED A STRAIN
Breeding cannabis strains is all about manipulating gene
frequencies. Most strains that are sold by reputable breeders through
seed-banks are very uniform in growth. This means the breeder has
attempted to lock certain genes down so that the genotypes of those
traits are homozygous.
If we can imagine for a moment that a breeder has two strains
- Master Kush and Silver haze. The breeder lists a few traits that they
like. * Donates the trait that they like.
This means that they want to create a plant with the following features
and call it something like Silver Kush.
Now all the genetics that they need are in both of the gene pools for
Master Kush and Silver Haze. We could just mix both populations and
hope for the best or we could try to save time, space and money by
calculating the genotype for each trait and using the results to create a
TRUE BREEDING STRAIN (An IBL).
The first thing the breeder must do is to understand the
genotype of every trait that is featured in his/her ‘ideal’ strain. In order
to do this the genotype of each parent strain or population for that
same trait must be understood. Since there are 4 traits that the breeder
is trying to isolate then 4 x 2 = 8 Genotypes for these phenotype
expressions must be made known to the breeder.
Let us take the Pale Green Leaf of the Silver Haze for starters.
The breeder will grow out as many Silver Haze plants as they can find.
They will then note down if any of the population have any other leaf
color trait. I
For a cash cropper with a lot of free time then it might be a good strain, but the buyers will search for the resin gland
on the budz, it can be a problem for those who sell their crop. If I compare the Kong to the numerous Big Bud
harvests I have seen, there is nothing so special about the yield of the Kong, it is just a very good yielder but
still very unstable judging by those last Kong report we have read lately. So the final thoughts are: No, I would
not buy the Kong for my own personal smoke (potency, buzz and ordinary taste) and No neither I won't use
this strain for a future crop even if the yield was really good, because of the Time/yield factor. But yes, a
newbie would find this strain very interesting and he would be happy to tell his friends that he have had a hell
of a good yield. I can't give the Weight details on the board, but I can say that 4 clones = 1 pound. (Almost
the double weight of the northern light but it took much longer to achieve it though).” – Orchid Man
