Creating True Breeding Strains By Vic High

My guess is yes, I see no reason why it would not.
But one would need to try in a proper experiment to be sure to what degree.
I have used it as herm-away on late flowering plants for years.
I have never had it not work, but there may be a plant out there that will not respond to it.

Edit:
I had to look the term up for accuracy.
(Although monoecious plants are often referred to as “hermaphrodites”, true hermaphrodites – which are less common in Cannabis – bear staminate and pistillate structures together on individual flowers, whereas monoecious plants bear male and female flowers at different locations on the same plant .)

I must admit, I did not know the difference… :exploding_head:
So I feel I must state…
I have not tried it on a true monoecious plant with male and female flowers on the same plant at different locations…AKA monoecious

Now I want to know more, you cryptic bastard… :rofl: :joy: :rofl:

Totally agree, I was thinking for plants that are well expressed in their sexuality like mother plant and wanting to work with the clones and decide to either make weed or seed.

Yes I like the idea of 6-BAP or gibberellic acid for deciding which sex you want to express while immature :+1:.

These hormones drive the machinery so why not use them.

This is where the confusion for me sets in though when talking about cannabis or hemp.

“ Using selective plant breeding, monoecious industrial hemp varieties have become more prevalent. Monoecious varieties exhibit both male and female reproductive organs on the same individual plant. Without plant breeding, intervention, and maintenance, hemp varieties would revert to their natural dioecious state”.

:+1: Yes and I wonder if two unrelated inbred or homozygous lines are crossed then you get the heterosis and then cross the f1’s self or full sib then you see the transgressive segregation or cross over the shows up at 5% so you don’t have the typical AB or ab, but the aB or Ab. Thing I find funny is big A in a Thai might act like a little a when going against a big A of some Afghani. Dominant and recessive depending on the types being crossed sometimes.

I wonder if the super recessive action mentioned in article could be from an epistatic recessive reaction?

In the f1, heterosis will mask weaknesses and more plants will appear to be transgressive then there really are. Once they segregate in the f2+ is where we should fish out additives…

And they stack too.

That was stolen from the @Comacus thread.
It does seem like a likely candidate for our project. :grin:

Why do you see potential? Usually they’re not very popular at parties :grin:
For the 75% female population maybe?

I am looking at the plasticity of the type perse in that it is possibly more likely candidate for Apomixis/apogamy.

I think the plasticity of certain types makes steering a little easier if you now have a steering wheel and know the direction you want to go.

Yes, transposons and epigenetic regulation can be studied in hemp. Transposons, also known as jumping genes, are mobile genetic elements that can move within a genome and cause mutations. Epigenetic regulation refers to the control of gene expression via modifications to DNA or histones that do not involve changes to the underlying DNA sequence. Both of these areas of research can provide insight into the genetics and molecular biology of hemp, and can help improve the understanding of how these systems impact hemp’s traits and characteristics.

Mitochondria play a crucial role in apomixis as they are responsible for providing energy to the developing embryo in the absence of fertilization. Mitochondria also inherit their DNA from the maternal parent, which is important in the maintenance of maternal traits in apomictic offspring. Additionally, mutations in mitochrondrial DNA can lead to genomic instability, which has been shown to occur frequently in apomixis.

Well @shag I thought I would post this link of a person of interest when looking at apomixis.

I will have to disagree. :weary:
It is on topic…
Apomixis is about as true breeding as it gets. :slightly_smiling_face:

@Mithridate @shag Yep just trying to keep all the topics on point but you know what I mean :cactus:. Yes this is very interesting stuff and can have at least 80% success rate just need to tweak it. Sharbel stated that he is also delving into the cannabiniod side of the research so should be very interesting.

From what Sharbel stated with the type he is working with is just a handful of genes (20-40) so looks promising with apomixis being the next revolution for plants. Going into the Y chromosome idea that it is needed to start the process of apomixis. This would make sense but then something must not get produced to down regulate the suppression of the apo genes and allow the apogamy apomixis to happen. Thus it is a matter of inheriting the correct genes but also having the right signals to turn male expression (tissues) into female tissues. Basically turning meiosis into mitosis but need the trigger to induce pollination but then turn off the down regulation or suppression of apomixis to produce clonal gamete of the mother cell.

Egg cell fooled

A group from Wageningen University & Research was also involved in the study and showed that the PAR gene is normally inactive in egg cells. The PAR gene normally only becomes active in the egg cell after fertilization, it then divides to create a plant embryo. In the egg cells of dandelion plants that form seeds via apomixis, the PAR gene proved to be switched ‘on’ prior to fertilization. In other words, these egg cells ‘think’ they are fertilized and start dividing without fertilization has taken place.

Hawkweed

In New Zealand, parthenogenesis genes are also being studied by researchers at Lincoln University and at Plant & Food Research. Their research focuses on hawkweed, a plant genus that Gregor Mendel studied extensively. In the mid-1800s, Mendel noted that plant characters were inherited differently in peas and hawkweed but he was not able to explain why. We now know that this is because peas reproduce sexually while hawkweeds reproduce by apomixis.

Hawkweeds and dandelion belong to the same plant family so the New Zealand researchers compared the PAR gene found in dandelion with the genes of hawkweed and discovered something that the team also observed in dandelions: while all plants contain PAR genes, the plants with apomixis had an extra piece of DNA just in this gene. This extra DNA appeared to be in almost the same place in the hawkweed as in dandelion, even though the plants are believed to have separated from a common ancestor more than 13 million years ago.

Further analysis revealed that the extra piece of DNA was a so-called transposon: a piece of DNA that can ‘jump’ within the plant DNA. In hawkweed and dandelion, the transposon is positioned in the promotor, the region of the PAR gene that regulates the gene’s activity. The researchers now suppose that these jumping genes ended up in the promotor of the PAR gene independently in both plant species and that this is a case of parallel evolution.
