just to clarify before we go further, I'm right in thinking you call a herm a reversable plant that sheds pollen ?

I wouldn't use that definition. Some herms are not reversible.

I get the feeling that you would like tie me up with definitions, e.g.

"theres NO hermaphrodite specimens with cannabis just plants with both male and female flowers live on one plant are called monoecious(intersexual). And Plants with male and female flowers borne on separate plants are termed dioecious."

I doubt that the above statement is correct, but I don't wish to get into a debate about semantics, this is a cannabis forum. In common parlance, a hermaphrodite that is female that produces male flowers that contain pollen.

I don't feel this is constructive or going anywhere, I will say to produce XX x XX I'd find the plants that are stress resistant self them to reveal all about them and reverse the chosen ones, perhaps I should just be using these "true females" perhaps not? but then I should be using these for all breeding by that logic.

Well I glad that you are stating your position. I'm assuming that you believe that XX plants are reversible. I don't believe this to be true. My theory is that any female that produces pollen is by definition XX'. Males can also be X'Y and then all of the daughters are herms. That's why fems worry me. You see I like males ( In a non homo-erotic kind of way). It was the Haze males that gave us so much, not the females.
Sex reversal is a tool. I preferred to turn the Skunk males into ladyboys. When I couldn't get certain females to go butch, I formed my opinions and let it go. I am not a world authority on Fems, I've never made them professionally or sold fem seeds. There are those that do, perhaps they would like to voice their opinions. I may learn something.

All this talk of old skool NL5.. Is there any chance we could see this girl in all her glory again?? as all NL now is bland poop...

p.s interesting stuff for a pollen chucker like my self...

Ok if its not true with these "XX" only you, SamS and if some would have you believe those with the Exodus Cheese (though this doesn't hold true imo) have these irreversable plants... but you have stated they showed balls etc but shed no pollen? the reason for selfing chosen or desirable plants is to flush out undesirables ie those that segregate to f**k and test them for intersex traits.. I fully agree that reversel is a tool and not the be all and end all, but I have never taken this position.. I fully endorse the reversal of males.. imo its a great tool.. I don't think theres many out there that does proper breeding regardless of M/F F/F or incorporating both etc... I can fully understand the worry with females but for me theres the same worry with M/F matings.. I think its one thing Hyb regrets is informing people about reversal as it is misused but thats not the tools fault its the users.

hi all

firs of all I'd like to make a few remarks :

to moonunit : the grosse lisse is indeed one of the old french cultivars but there must be at least 20 types of grosses lisses depending on their origin, there are still cultivated but some more typical cultivars such as marmande tomato is preffered to it. I'm not aware of the german one. You can contact some collectives that are implicated in the conservation of old tomato varieties, I'm sure they would be ready to help you, but I'm more into carrots and onions at the moment (cannabis should follow quite soon):D

to Krk: your posts are always nice and interesting, sorry for the earlier remark, I just though you wanted to be impressive, even so the article was interesting but not so much linked to the topic. but you're totally right that some people were just waiting for that; anyway thanks for inviting me to the other forum.

to nevil and kopite you (nevil) must have been able to some heck of experiences at that time... I would have loved to. Nevertheless, I must say that a
hermaphrodite plantt is a plant that bears male and female sex on the same plant, in the same flower such as the big majority of angiospermes with the sepals, then petals, then stamens (male) and finaly stigmate (femelle).

a monoecious plant has male and female sex on the same plant, on the same inflorescence or on different inflorescences. the inflorescence bears flowers.

a deoecious plant has only one type of sex on the plant;

researchers accepts the fact that cannabis may somtimes show some hermaphrodite characteristics with male flowers produced from female flowers (typically what can be seen with sex reversion).


Even if some people think it is stupid, I believe using the right terms is more proper especially in quite specific talks like that.

a sex reversed plant is herma
a normal "herma" plant is monoecious
a normal "normal" canna plant is deoicious.



I believe that Nevil's therory of Xm/Xm (scientific way of writting X'/X') versus X/X real femal chromosomes is very interesting, it could very much explain a lot of things, nevertheless one must no forget the theory of the ratio X/Y for sex determinism :

if the ratio is 2 (2X/0Y, not very mathematical but nevermind) it gives a femal

if the ratio is one (1X/1Y) it gives a male

odd ratios such as (3X/1Y) gave only female in previous experiments
this would tell that the Y chromosome hasn't got any factor for determining the sex, only the ratio is important, but this is a theory.

we have to be aware that even the most up to date researches (especially the G. Mandolino's team working on hemp) are still not sure of how sex determinism works,
it is well known that plants turn from allogamy to autogamy every so ofter so does herma plant turn to dioecious plants (because of male or female sterility mutations). these a natural mechanisms that are very usefull to get diversity (heterozygote with allogamy) and then to switch into a conservation mode (autogamy/homozygote plants).


My last remark to myself

Nobody has talked about the heterogamic cross that happens in cannabis (like in every other angiosperme) : the mother plant gives all the cytoplasmic genetical material and, as know, many traits are linked to mitochondrial or chloroplastic genes such as sterility and resistance to pest or herbicides.

The use of sex reversion could also be a very useful tool to change the ways of cross (Afemale x Bmale or Amale x Bfemale) and so change who gives the cytoplasmic material . this needs to be worked on.

I just had a quote I wanted to do

You see I like males ( In a non homo-erotic kind of way). It was the Haze males that gave us so much, not the females

I believe it was just the way it was, it that case, the favourable traits were kept in a plant that turned to be a male, but it is not because it was a male that the traits given were good.

I'm being told off by my girlfriend... time to eat!

cheers

From this article...
http://www.bio.uaic.ro/publicatii/a...d/2007_VIII_f2/2007_Anale_GBM_VIII_f2_l07.pdf

Is this your train of thought Nevil?

Frankel and Galun, 1977 affirm that the males are X/Y, and the females are X/X. Besides that, the allele
Xm exists, that determines the appearence of male flowers in female inflorescence. Thus, X/Xm plants have
female inflorescence, but they can be not strictly females. Depending on genetic and non-genetic additional
factors, these plants tend to masculinization, reason for which Kőhler named them “subgynoecious”. The
Xm/Xm plants will have female inflorescence, but functionally are males. Considering the results obtained in
various studies on polyploids by other researchers, Kőhler concluded that the masculinizing genes are
autosomal and they are balanced by femaleness carrying genes of X chromosome, while the Y chromosome
is “empty” under the aspect of sex determining genes.
Analysing these arguments and hypotheses, the following models were established:
- male plants with male inflorescence: X/Y, Xm/Y;
- male plants with female inflorescence, Xm/Xm;
- variable phenotypes, from true females to monoecious plants, but all with female
inflorescence, Xm/X;
- female plants with inflorescence of female type, X/X.
 
Stop starting shit b0b!

Personally don't think Bob did anything.. one thing I do hate are people who hide/sneak call it what you will... I feel you have done that Mr Fresh Genetics why the need for this ID and JB ? why the need to post using both? you are one or the other or do you have a prob with split personalities?

@bonbolos, you clearly have a good head on young shoulders.. take care.
 
hi all

it seems that this thread has not much else to give, as a conclusion I think that :

.we all agree on the importance of protecting cannabis diversity, and of the problems linked to bad quality breeding with fem seeds
.some of us do understand that sex revers techniques may be usefull tools if integrated in specific breeding programs with specific goal and real breeders,
.the release of fem seeds for commercial purpose is more complex and may lead to loss of diversity (at a certain extend) and herma problems
.more professional research needs to be done on the heredity of sex in cannabis



@bonbolos, you clearly have a good head on young shoulders.. take care.

I'm very much touched by this remark, :o:) cheers man, I'm looking forward to gain more experience with age and interaction with other very interesting people such as you and the MNS community.


I thank everyone for the more (or less) constructive comments, it did make evolve my way of thinking things thru.


Cheers

I like your style krk
No excess verbiage. Full of information. As I see it, the position you take is the same as mine, but using different symbols.

hay hempy,,:),,,,check me out on MrNiceSeedsfourm :),,,,im a baby over here:),,,,nice place you guys have here:)

i understand there will allways be many camps working in many different directions,,,,

i see you in the camp that will never be intrested in feminization,,thats cool!!,,,but your camp is pretty big,,,,our camp [the fem breeding camp] is pretty small when it comes to breeders,,,so i guess we are just recruting at the min,,,

i love all the cannabis camps,,,i just wish shanti would supply our camp aswell as your camp,,,im sure he could do both

From the paper krk posted I'd say its safe to say that the intersex is autosomal and can be masked - hence why I feel selfing is extremely important...

The ONLY camp there should be is the one whos interest is for the better of cannabis.
 
Thanks for all of these amazing lessons in genetics. Much better then sitting in a classroom. Please forgive my lack of understanding. I'm here for knowledge.

bonlobos-"we have to be aware that even the most up to date researches (especially the G. Mandolino's team working on hemp) are still not sure of how sex determinism works,"

Alligator eggs within a nest are normally all one sex or the other when they hatch. Scientists figured out the temperature of the nest was the determining factor. It is my hunch that the same will be found to be true for cannabis. Is it possible for a gene to be influenced by some outside natural force like temp or light spectrum? I appologize for my ignorance but I had to interrupt because sex determinism is a topic which has interested me for a long time. :)_~

many camps,,,with parralell intrest,,,all fighting for the same goal

but its cool for us to have a conflict of intrest,,,,conflic promotes segregation ,,,segregation is the basis of disruptive selection,,,imo

Light, temp, insects in soil can all effect the gene or genes at play, but the plant has to have those genes in the 1st place... personally I feel the closest I have read in relation to sex determination within cannabis is that of silene dioica

so we know it interacts on the PAR

I see how you looking on things Kopite but Im not sure is that right.

There is only XX & XY what is common and normal by any bio or med standards but XXY is not so much rare or like you quote XmX.

Any other variation except XX or XY is taken for anomalia and that is for what I think you were wrong.

At humans and animals Klinefelter's syndrome can in some parts explain this, but I still didnt read its common but XX & XY ... its same with plants.

Like you quote here, plant groups
Just find groups of plant species by sexing and you will see where cannabis belongs.Its a group of separate sex where for fillial is required two plants not one.
So what brings XX x XXY ? is that pure XX filial ? I dont think so and there is where "100% females" dropping in the water.
