Selfish is a last ditch effort by a plant to save the genetics if a plant has not been Polinated, whether done by nature or by man, it is a technical inbreed. It is not a way to continually pass on good generics, they will degrade over time.

A clone IS the mother plant, no genetics have been "passed on" as it is the original plant weather it's the first clone taken or the 1000th. This is why a Comercial grow clones from mothers and doesn't grow from seed, stability of genetics.

To correctly pass on genetics for untold generations, a male and female will be needed for any individual strain.

I am by no means an expert, but have grown for close to 30 yrs and this is what I've seen, having both, cloned same mother for several years, and selfed genetics to save a strain that couldn't be replaced. The genetics come from the mother, but are not an exact copy of the mothers.

hi Arthur,

Do you believe there is a difference, in terms of DNA, between:
(*) The mother plant
(*) Plants grown from the seeds, of the self-fertilization, of the mother plant.

If they have different DNA, please explain why.

Thanks for your help

Yes, when you self a plant, you take all the mothers DNA (from both her mother and father, both used and unused dna) and but it back in the original shaker and reshake. It could come out as the mother, or an infinite number of phenos.
Selfing works, it's just not the best way to do it. Just like cloning a clone works, but the farther you take it the poorer it will get.

Always figured any argument with the law on [HASHTAG]#s[/HASHTAG] I'd say yes, there is 1 plant not 30. She just needs 30 pots to live in.

The more i think about it, I realise, the resulting seeds, from self-pollination,
are highly unlikely to be clones. I had assumed that since the
genetic source, for both parents, was the same mother plant, then the result
must be a clone of the mother.

However, that's clearly not correct, because there is usually two genes,
coding for the same function, one from the mother plant, and one from the
father plant. For example.....

Let's take the (famous) case of the genes, in cannabis plants, coding for the
enzymatic conversion of cannabigerol (carboxylated) CBGa.
Cannabis has two of these enzymes, one donated by the father plant, one
donated by the mother plant. These enzymes convert (carboxylated) cannabigerol
to (carboxylated) cannabidiol (CBDa).... or .... they convert (carboxylated) cannabigerol
to (carboxylated) Tetrahydrocannabinol (THCa). And so, for example, a mother plant
that inherits two copies of the CBGa-->THCa enzyme would be a strain with a
CBD:THC ratio that heavily favours THC. Perhaps 20:1.

Consider a plant that possesses the CBGa-->CBDa enzyme from 'mom',
and the CBGa-->THCa enzyme from 'dad'. Theoretically, this plant will render a
CBD:THC ratio of approximately 1:1 (ignoring any complicating factors like the
relative dominance of the alleles coding for these enzymes).

But now consider the 'children' of this (self-pollinated) plant. Again, let's ignore the
complications of complete and incomplete gene dominance for a moment, and
let's assume that genes are shuffled randomly. The self-pollinated seeds will
likely show this pattern of enzymes:
25% will have two lots of CBGa-->THCa
25% will have two lots of CBGa-->CBDa
50% will have both CBGa-->THCa and CBGa-->CBDa

And that's just focusing on one gene. I remember reading recently that there are
78 (non-mutated) genes in cannabis, that are free to vary. So if you consider
the random shuffle against these other 77 genes, then it's clear that the resulting
seeds are highly unlikely to be clones (although, potentially, a clone could possibly
emerge).

Thanks for posting, Arthur, i learned something.

Have a nice day

Well your way ahead of were I am in genetics, but sometimes it's just a look from a different angle.

Some I've seen, (different phenos in the seeds of a selfed plant) and some I've heard, from some pretty large breeders out here on the west coast. They'll self, but only as a last resort.

Will admit have become fascinated with genetics in cannabis, probably know just enough to be dangerous!

Well, there are some true "perfect flowers" out there, that even when perfectly healthy grow male parts too, but in much smaller quantity. I think I may actually have one of those in my tent atm, a photoperiod mind you. It's actually the reason I'm building myself a mini growbox atm.. So take cuttings, reveg them, sts them and see if it was an anomaly or gentics.
I could just take the pollen from the male bits but that would muddy my waters.

I just found this site, thought you'd find it interesting as well @cryptolab. They're collecting cannabis dna, and plotting it. On the site it's completely interactive. Very interesting to see what strains are made of!

I am getting ready to harvest my auto in a day or two. Maybe I will give it a try. I will start with the beginning of the feeding schedule and see what happens.

Hi Seb,

how many buds do you have on this plant ?
Is it like, one central cola, or do you have buds on peripheral branches too ?

Aside from performing Low Stress Harvesting, LSH, to extend the flowering period,
(LSH - harvesting only the obviously ripe buds, every 3 or 4 or 5 days),
you also have the option, similar to Low Stress Training (LST), to get additional
mileage from this flowering period, by raising a budless peripheral branch,
such that it's higher than all the other buds (might involve bending budded
branches down)

I would be very interested to follow the progress of your harvest.

be happy

There's about 18 buds on this plant,with 1 main bud. I didn't LST this plant. It was my first real grow. I will be doing it on future grows. I checked the plant very careful today and the buds have little amber, cloudy and little clear tric's on it. There are buds that don't have full light exposure probably can use a another few days to finish. I have another plant that is about 4 weeks behind this one. I have learned so much since I started this grow and purchased 5 3500k Cobs from BigSm0 can't wait to start my next grow.

hi Seb56,
sounds very interesting.
