BREEDING- Cannabis Marijuana seeds Growing Guide
It is possible to breed and select cuttings from plants
that grow, flower, and mature faster. Some plants will
naturally be better than others in this regard, and it is easy
to select not only the most potent plants to clone or breed,
but the fastest growing/flowering plants as well. Find your
fastest growth plant, and breed it with your "best high" male
for fast flowering, potent strains. Clone your fastest, best
high plant for the quickest monocrop garden possible. Over
time, it will save you a lot of waiting around for your plants
to mature.
When a male is starting to flower (2-4 weeks before the
females) it should be removed from the females so it does not
pollinate them. It is taken to a separate area. Any place that
gets just a few hours of light per day will be adequate,
including close to a window in a separate room in the house.
Put newspaper or glass under it to catch the pollen as the
flowers drop it.
Keep a male alive indefinitely by bending the top severely
and putting it in mild shock that delays it is maturity. Or
take the tops as they mature and put the branches in water,
over a piece of plate glass. Shake the branches every morning
to release pollen onto the glass and then scrap it with a
razor blade to collect it. A male pruned in this fashion stays
alive indefinately and will continue to produce flowers if it
gets suitable dark periods. This is much better than putting
pollen in the freezer! Fresh pollen is always best.
Save pollen in an air tight bag in the freezer. It will be
good for about a month. It may be several more weeks before
the females are ready to pollinate. Put a paper towel in the
bag with it to act as a desecant.
A plant is ready to pollinate 2 weeks after the clusters of
female flowers first appear. If you pollinate too early, it
may not work. Wait until the female flowers are well
established, but still all while hairs are showing.
Turn off all fans. Use a paper bag to pollinate a branch of
a female plant. Use different pollen from two males on
separate branches. Wrap the bag around the branch and seal it
at the opening to the branch. Shake the branch vigorously. Wet
the paper bag after a few minutes with a sprayer and then
carefully remove it. Large plastic zip-lock bags also. Slip
the bag over the male branch and shake the pollen loose.
Carefully remove the bad and zip it up. It should be very
dusty with pollen. To pollinate, place it over a single branch
of the female, zipping it up sideways around the stem so no
pollen leaks out. Shake the bag and the stem at the same time.
Allow to settle for an hour or two and shake it again. Remove
it a few hours later. Your branch is now well pollinated and
should show signs of visible seed production in 2 weeks, with
ripe seeds splitting the calyxes by 3-6 weeks. One pollinated
branch can create hundreds of seeds, so it should not be
necessary to pollinate more than one or two branches in many
cases.
When crossing two different varieties, a third variety of
plant will be created. If you know what characteristics your
looking for in a new strain, you will need several plants to
choose from in order to have the best chance of finding all
the qualities desired. Sometimes, if the two plants bred had
dominant genes for certain characteristics, it will be
impossible to get the plant you want from one single cross. In
this case, it is necessary to interbreed two plants from the
same batch of resultant seeds from the initial cross. In this
fashion, recesive genes will become available, and the plant
character you desire may only be possible in this manner.
Usually, it is desirable only to cross two strains that are
very different. In this manner, one usually arrives at what is
refered to as "hybrid vigor". In other words, often the best
strains are created by taking two very different strains and
mating them. Less robust plants may be the result of
interbreeding, since it opens up recesive gene traits that may
lead to reduced potency.
Hybrid offspring will all be very different from each
other. Each plant grown from the same batch of seeds collected
from the same plant, will be different. It is then necessary
to try each plant separately and decide it is individual
merits for yourself. If you find one that seems to be head and
shoulders above the rest in terms of early flowering, high
yield and get buzz, that is the plant to clone and continue
breeding.
In depth genetics is beyond the scope of this work. See
