Clone of a Clone of a... Degredation Experiment

So I was having a debate with an experienced grower about clone degradation. I'll tell you first about the debate we were having so anybody can weigh in.

Second I will tell you about the idea I had for a side by side experiment involving harvesting "excellent" Clones and starting an excellent clone line. Next to it I will also have a "poor" clone line. If enough people are interested in it and my hypothesis still holds enough water that it is worth investigating after everybody picks it apart, than I will conduct the experiment in my 5 kW garden.

The debate: Regulator Dave (RD) vs. The dude

The dude called first generation clones "F1" , 2nd generation "F2" and third "F3" and so on. He was very adamant about the idea that clone stalk is only for commercial growers and that all clones grow shitty herb.

Dude says: " I would never grow with anything that did not come from the generation of clones from the mother grown from seed "

So his "F1 clones" were the only viable clone. He then gave a bunch of examples of growers that had declining quality with clones. He was solid in his position and believed without a doubt that anything past an "F2" is a shit clone. His method of propagation is to plant a seed, veg the mom and then take clones from the mom and grow those to harvest.

I told him I just could not agree that growing from seed would overall be a better strategy to grow the Sticky Icky Dank. I told him that the laws of probability and statistics were against him with that strategy, and that it was foolish to not grow proven clone only winners.

We held onto the debate for about 20 minutes after we put the Power Kush blunt out. Both sticking to our positions. We both did agree that it is known that seeds have around 25- 30% more growth vigor than their clone counterpart. I claimed though that aside from the 25 % loss, the idea that an "F3" clone and beyond is a shit clone just does not seem true to me. And further that after the initial shift from seeded plant to cloned plant there is no further degradation.

After I made it home the conversation continued to rattle around in my brain. Something to keep in mind is that despite the fact that his idea went against the "truths" I have come to know, He spoke with much experience and was quite knowledgeable in other cannatopics. I wanted to give his ideas a fair subjective chance to change my own.

The conclusion I came too was last night when we got home led me to wonder if we were both ....right???


I just met the guy and may not have a chance to talk to him again. But I would like to ask him some questions. Feel free to answer them if you'd like. I will be grinning if there are people that take both sides of this debate.

Would he consider this to NOT be a generative way to take clones from a seed grown mother If: You grow the mother out continually take clones from it while keeping it in veg. say even for a long time, maybe even years, always growing to harvest his "F1" clones. This method would not go against his theory that a clone is only good that is from the SAME generation. The mother plant would always be a first generation from seed plant and the clones would always be of the same generation i.e "F1" his "good" clones.

Lets assume that he would say yes, actually I think he would have to say yes because it does not break any rules of his theory.

So with that in mind I would ask him this, do you think that it is the process of cloning that causes the degeneration? Or do you think it is the age of the plant that causes the degeneration. Or is there another explanation I do not see yet.

Challenging his theory:

A clone from a mother from seed is the same plant and is the same age as the mother. If you grew the clone and the mom side by side they would still be the same generation. If you took a clone from that clone and grew it next to both the mother from seed and the first clone from the mother they would all be the same age and so on and so on. No matter how many clones from clones from clones you took originating from the seed mother they would always still be the same age as the mother that they were growing next to.

Now remove the mother from the scenario, after you take the first clone, say the mom goes into flower, the clone is still the same age as the mom would have been. If you take a clone from a clone from a clone ect. The resulting clone is still and into eternity the same age as the mother would have been. So the age thing does not really hold water. Right?

So the only way cloning could cause degeneration is if it was due to the process of cloning. The only way I can see that happening is by taking crappy clones that barely live and grow really slow for the rest of their life and possibly for the rest of the life of all the clones that come from it.
If you take an excellent clone and the plant never gets stunted, the plant does not lose any chlorophyll from the leaves and looks exactly like it did when it was cut (which with our method of rooting clones they often don't change at all) the growth should be the same and should continue being the same if the only clones kept were excellent clones that never got stressed. This is applied vise versa for crappy clones taken from crappy clones.

All this amounts to is that his theory states: If you take crappy clones you get crappy plants, right?

Finally to the more interesting part. The side by side experiment.

Experiment design

I will take one of my seedlings (blue satellite 2.2), take both good clones and bad clones, we'll take one of the really crappy slow growers and we'll take one of the excellent clones and we will veg them until we can take clones from them.
Then we will grow out and flower the clone from the excellent clone and the clone from the crappy clone and compare them to see if there has been any degeneration. We could even run this experiment longer, always taking crappy clones from the crappy clones............. and always take excellent clones from excellent clones from excellent clones............I would be willing to run it for a long time as long as the quality of the B.S 2.2 is acceptable.

We could observe and see how many generations it takes for degeneration to occur, and we would also see the difference between a good clone line and a bad clone line.

My hypothesis is that the good clone line will always result in better plants & end result than the bad clone line assuming all conditions between the two stay constant we would give "good" line and the "bad" line everything the exact same.

Crappy clones make crappy plants.. So if my hypothesis is right the Dude and I are both right?

If my hypothesis is correct would it mean that if at anytime the clone line you have, has had one bad clone in the hierarchy the whole downstream clone line is degraded?

So I hope this thread sparks some interest and I hope the experiment is worth doing because it seems like it would be fun.

Lastly I want to say that I have a very thorough knowledge in experimental design and statistics. So the experiment would be done well.
 
An unhealthy clone whose health does not recover will give you unhealthy cuttings. Nurse an unhealthy clone back to health and you will have healthy cuttings. DNA does not change just because a cutting is unhealthy, so I don't know what The Dude is talking about when he claims continual cloning degrades final product. As long as the mom remains healthy, all is well. I'm willing to bet he and other folks did not keep mothers as healthy as they thought they were.

Looking forward to your experiment.

that is interesting!
the clones have genes same as mother...if mom was healthy then all clones have the propensity to express those same genes, regardless of how many bad clones or good clones, the genes aren't about to change.
maybe due to environmental concerns the clones would not be able to optimize that potential.
just my opinion

A group of us growers have been running the same clone only cuts for over 6 years. We have swapped the same clones over and over between us and have grown and shared hundreds of new mothers from clone after clone. We have seen zero deteriation in over all yield, vigor or quality period. This guy you have been talking too has no clue whats hes talking about. Thier are a ton of commercial growers who will share the same experaince. How old is the chemdog D cut? Think about how Chemdog and og kush are still some of the strongest and most sought after plants. If cloneing caused weakness you would not have these clone only strains still have such an impact.

I cant back it up, but I have not noticed any degradation of my clones even after using them taking clones then flowering the mothers, veg back to moms, and repeat. the plants look BETTER each time.

The secret to my success is simple. ***I learn to take better care of them each grow which maximizes my quality and quantity***

=)

I support the idea of *No degradation in cloning*

All I have to say is I'm pulling up my chair, I have always been taught the theory of the dude and can't say I have ever seen proof in my experience of this except my Blue Dream cut is so fucking awesome except never yields like they say it used too. This is a clone only strain.....makes me wonder cause it is def the b.d.

hm this experiment would be very good to do event tho i can promise there will be no degradation or what so ever is called:

- DNA doesnt change because of stress:
bad lighting
bad watering
flowering

- DNA does change because of:
Radiation
UV-Light
very few Chemicals

like said above - unhealthy clones always are as good as healthy ones if given time to recover.
ACCEPT you caught a virus - but then you are screwed anyways ...

unless you put your plants in a nuclear power plant, your ozone generator or dip it in some nasty chemical there will be no way that your clone in generation x is worse than the one you have now. there are ppl on the board who actually have side by side experiences over 20 years - one clone from clone, other one from one mother plant - they were just the same after many years!
if you get into science and genetics you'll find out that most things you belive are so, are just not so. also: hybrid vigor is in clones as well from what ive read and from my experience.

i would be happy if you do this experiment because this has gone far too long - nearly everybody in the scence still belives that genetics degrade


wikipedia DNA:
"DNA, is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms"
"DNA is often compared to a set of blueprints, like a recipe or a code, since it contains the instructions needed to construct other components of cells, such as proteins and RNA molecules."

wikipedia DNA-Mutation:
"Two classes of mutations are spontaneous mutations (molecular decay) and induced mutations caused by mutagens."

spontaneous mutations usually are repaired by the cell itself - just the very big induced mutations cant

if you know the science you knoe the outcome of this experiment

The only degradation of a clone would be it's lack of an optimal growing environment just like any plant in nature..IMHO

This test has been run for many years already by those of us right here in the community growing the same clone for sometimes well over 20 years. Clone of a clone of a clone ... doesnt change. Can you say TrainWreck.... just as example ... look how long this girl has been passed around :) I say the test is over the results are in

Technically, all you & your friends have been passing on are cuttings, and along with perhaps 98% of the cannabis culture out there. "Clones" just happens to be the popular jargon of those, who are into propagating an exceptional cannabis plant. So as a result; there is no need to worry about any genetic degradation, because when you take a cutting, none of the genetic material has been altered.

The same cannot be said when growers clone orchids. This is taking minute tissue material, and then reproduce an award quality plant with thousands of offspring from just one flask. All the offspring are not the exact same genetic make-up of the original parent, to put it in very broad terms.

To explain fully, I'd have to start a thread with several pages, but I hope I was able to dispense any worrying on your part. You could take cuttings for centuries, and still not have to worry about any genetic changes.:watchplant:

I would just add, i have cloned f1 hybrid, taken that clone regenerated it took clone from it grew it out regenerated it, cloned that 1, and vigor has still remained better then the seeds im using to supplement and have variety. It is a tad less robust then its great great great great grandmother but i think its gaining in potency, entirely subjective and many environmental issues have changed!

My observation, with 1 plant is THIS PLANT has lost a little growth vigor from the seed version in comparison to the clone of that seed version, but has lost no potency and has made little changes if any at all(this is contrary to my goals !) i want a budding flowering compact dense nuggets to go with my INCREDIBLE RESIN and FLAVOR. Ya cant always get what you want---------- However I must side with you on my observations. Clone several generations down the line can be just as healthy with a small loss off growth vigor. However it is seeming harder n harder to clone it, but i dont think thats the multiple cloning that is making it more difficult, i have hardly any humidity in the winter and that does seem to be a problem with rooting. It may be a strain issue, some strains do some dont do well several generations away from seed mom, Certainly they all dont show same loss in vigor some are total dogs in cloning maybe he ran into some bad strains to take clones from!!

If you photo copy a document, and keep copying the copies, the document becomes illegible.

In the movie multiplicity one of the clones decided to clone himself, and that copy came out retarded.

But with cloning cannabis plants, there is no degredation, and if there is it would be undetectable by humans. My moms would always get outta control, would take a clone and flower the mom, using the cutting as the new mom. Loads easier than trying to tame the hydra.

Clones of clones of clones for 20+ years is no problem as long as the plants are well maintained and virus free.



What about Meristem-Tip Culture of Cannabis?
Under appropriate conditions, each shoot meristem can develop into a complete new plant or clone. Such new plants can be grown from shoot cuttings that contain an apical meristem. Root apical meristems are not readily cloned, however. This cloning is called asexual reproduction or vegetative reproduction and is widely practiced in horticulture to mass-produce plants of a desirable genotype. This process is also known as mericloning.
Propagating through cuttings is another form of vegetative propogation that initiates root or shoot production from secondary meristematic cambial cells. This explains why basal 'wounding' of shoot-borne cuttings often aids root formation.

This clone was a accident breakage of the 2 week flower plant,I put it in soil it rooted but had this crazy leaf pattern,I know when it goes back to the square 1 mode it might have 1 set of smooth but have never seen 3 leaf smooth?/ whatcha think guys??

Ahh, good question! And in a scenario of meristem, & mericloning there is slight genetic deviation. These procedures do not completely copy the genes to the offspring, and the only real benefits of doing this is to achieve thousands of plants in very little time.

Orchid nurseries are perfect examples of this. It could take hundreds or thousands of seedlings, several years to produce one or two award quality specimens. Those plants in turn, are mericloned for the guaranteed award quality bloom; however, since mericloning can slightly deviate the genes to the offspring, there are sometimes slightly different plants as a result, (not as good as the parent plant).

In short, it's no different than running copy after copy through the xerox. If you keep using offspring after the other as donors, you'll destroy the original makeup.
