First I didn’t say IBL but since you asked here’s a few:
Bubblegum
79 Xmas Bud
White Widow
Afghan Kush
Skunk #1
Northern Lights
Durban Poison
Hindu Kush
Malawi Gold
Columbian Gold
Maui Waui
Most are landrace but they are all still available.
As for stable genetics the list is much larger.
Strains like AK47, Sensi Star, Bubba Kush, Cali-O, C99 are all very stable genetics that I’ve grown personally.
The blueberry line has been worked heavily by DJ Short and others.
Hell even Tony Green is bxing gorilla bubble if you want a more recent strain.
Tell me where I can purchase any of these supposedly 'stable' / 'landrace' cultivars in seed form.
I’m buying one right now actually. 79 Xmas Bud. Search around. You’ll find the others.
C99 is out again by bros Grimm. Serious seeds has AK and bubblegum in stock everywhere. It’s not hard to find good proven and stable genetics. It really isn’t.
There are solid strains out there. I’m not going to argue genetics. I made my point. Been doing this since 2001. I’m well aware of marketing and hype. I’ve managed to avoid most of the garbage in the industry by keeping my eyes and ears open. Good luck finding your unicorn.
Great read @jumpincactus ..Question though..Were you stoned AF when you wrote that? LMFAO@Vikingvault
The original question the OP was asking was why his grow wasn't homogenous thruout the grow. There has been some good discussion here thus far. To answer the OP's question is, a lot of whats available out there as already mentioned are tent chuckers claiming to be breeders. They aren't working with enough numbers/populations with the work they are doing. A lot of these guyz are in it for the quick buck and aren't putting in the numbers, time and dedication and truly working a line. Locking out undesirable traits and locking down the characteristics they desire. For homogenous offspring a person has to work the line to where it is "true breeding".
If you are keen to breed your own strains of cannabis, then you are going to need to know how to stabilize the seed stock. Stabilizing a strain means it becomes homogeneous, and any seed from that strain will breed true. Classically, landraces are stable. A seed from one plant will grow the same way as another seed from another plant from the same crop.
Stabilizing happens naturally over time with a large enough crop. Climate, day length, altitude, and soil quality all contribute to the genetic makeup of cannabis. Given enough time, strains become homogeneous and breed true every time. For this reason, landraces has been used often for breeding as they have known traits that can be bred into new strains.
Stabilizing your indoor crop at home can be a little more difficult because of a number of factors. Limited numbers of plants means limited seed production. This usually means that the few seeds produced do not represent the complete new genetic diversification.
It is quite possible to produce only unwanted phenotypes in a complete grow. It is also possible that great-looking new phenos contain undesirable traits in the next generation.
The quantity of plants bred from a particular strain can also affect stabilization as well. There is a greater chance of “throwbacks” to earlier strains if there has been a lot of crossbreeding performed in the plant’s history.
Plants bred from only a few known stabilized strains will be more stable in their offspring. This can make the stabilizing process much simpler.
VARIABILITY & PREDICTABILITY
Variability and predictability are the variations in phenotypes and the expected ratio of distribution of different phenotypes. Genetics 101 foresees that breeding with stable parent stock will typically produce predictable results.
Offspring will be distributed relatively evenly across all the seeds in the batch. 25% will be father-dominant, 25% will be mother-dominant, and 50% will be hybrids with combined features.
Remember, this is across all the seeds produced. A random selection of four seeds will not necessarily produce the predicted variations. They may all be of one pheno or another.
This is why breeding on a small scale from a small range of seeds may not produce the variations as predicted. A majority of the seeds need to be planted to observe the predicted variations in phenotypes.
Without genetic assays that can give precise information about the plant’s characteristics, experience plays a big part. Growers rely on look, growth pattern, leaf shape, color, and potency for desired new strains. They select a number of plants for breeding from the same seed batch that have similar characteristics. These plants are interbred, and the plants that resemble the desired strain are bred together again.
Crossbreeding between four selected males and females can produce 10,000 different combinations of the targeted hybrid. These variations can be very subtle, and it is the master eye that distinguishes heroes from zeroes.
STABILITY & BACKCROSSING
It will take several generations to breed a stable new strain. Selective homozygous breeding, or breeding from within the same strain, produces less variations. Brothers crossed with sisters from relatively stable parents produce more predictable results.
Desirable dominant traits can be isolated and undesirable traits are gradually eliminated. Unstable parent stock risks producing heterozygous offspring. There is a risk of greater variation, and undesirable, unpredictable traits can emerge.
Many breeders will backcross with one of the original parents. It is not necessary to backcross to get stable plants—selective breeding will do this over time. However, backcrossing can speed up the stabilization process and reinforce preferred dominant characteristics.
INSTABILITY
The vicissitudes of plant genetics can be seen when driving past any modern food crop. Fields of heavily hybridized and inbred cereal crops, for example, will generally be homogeneous. However, there will always be some freaks that stand out from the crowd.
There is always the corn, wheat, or sorghum stalk that is too tall and takes longer to mature than its contemporaries. Or an atypical plant will grow with unexpected variations. These have expressed recessive genes, and are throwbacks to older styles of crop or attempts by the plant to express a different variant of the genetic combination.
The same occurs with marijuana. A batch of stable hybrid seeds can produce a plant resembling a grandparent or original landrace, the same way a redhead might happen here and there in a family with very few redheads in their genealogy. This is rare and can be an inconvenience or a boon.
A stable genetic like Skunk #1, for example, spontaneously produced the unique Cheese strain with no input from the growers. The particular seed recombined the DNA in a novel way that was outside the expected phenotypic variations. So don’t be bummed if you get some radical variations. You might stumble on the next big thing!
RISKS OF INBREEDING DEPRESSION
Homozygous breeding over a number of generations can refine a new strain splendidly. However, it does have its risks. As with animals, too much inbreeding can cause genetic depression. This is a lack of genetic diversity than can be detrimental to the overall health and sustainability of the strain.
Unwanted alleles that can negatively impact a strain are more likely to be passed on when both parents are carriers. When undesirable characteristics are passed on by both parents, the recessive characteristics become dominant and will be passed on to all subsequent offspring.
Outbreeding can solve these regressive attributes. When the breeding population is small, inbreeding depression can occur more rapidly. This is often a problem in Schedule 1 countries. The law means there simply isn’t the space to generate enough interbreeding stock to select prime examples.
The solution is to introduce a novel father into the gene pool to strengthen the strain by increasing genetic diversity. Within a few generations, the depression will be relieved and plants will regain their genetic vigor.
I sir am always stoned as fokk!!!!! :p Is there any other way to beGreat read @jumpincactus ..Question though..Were you stoned AF when you wrote that? LMFAO
Oh so fields of Kush in the afghan region used for making hash are planted from clones?
ya just gotta know the right person or be lucky enough to be in the right place at the right time,they are out thereMan, it's weird how all of these supposed landrace / IBL varieties are completely unavailable in seed form, despite the fact that it'd be trivial to reproduce them once they were obtained by anyone.
ya just gotta know the right person or be lucky enough to be in the right place at the right time,they are out there
Well said, they are out there for sure. People have to keep in mind that lots of folks who grow do not use the internet for anything canna related and would never sell seeds. I know of several around my area.ya just gotta know the right person or be lucky enough to be in the right place at the right time,they are out there
