yo greeninthethumb, you think charles xavier is wrong?

i can do my own punnett squares but explain to me what is wrong and why. what credibility do you have? what are you trying to argue? i almost have my degree, so i feel like i can speak a little bit about the subjects. why the hell would i need to do a punnett square for this? you can already tell the ratios just by looking at it... we are only dealing with 2 sex chromosomes from each parent.


(Note the nomenclature... This is dealing with sex chromosomes, not autosomes.)
Female = XX (can't argue with that)
Female S1 = XX (no Y chromosome because it only has copies of it's own chromosomes)
Female S1 x Male = XX x XY (50% Female, 50% Male)
... X ...X
X XX XX
Y XY XY

Was hoping someone else could look at it and figure it out but I guess I'll just toss this out there.

When you self a female (hopefully using hormones so you can use a true female with no intersex genes) S1 of XX obviously gives all XX.

But then you go on to write "S1 female x male" which for one thing doesn't even make sense. If you are selfing a female there is no male. When you use hormones to induce male flowers on a female you're not going to change it's chromosomes. You toss sts on a female and her dna does not change. Okay? If you're crossing a female to a male why would you say S1? Obviously you're not selfing her.

So where did you grow them out? They didn't even need a greenhouse to be able to finish? I guess you're sitting in a sweet spot. So how many individual plants did you grow out? When would they finish?

Do you think anything on the market captures your experience with the landrace seeds? Do you miss those plants?

And lets be honest here, it wasn't that you didn't NEED to clone her, it's that you didn't even know cloning was possible back then. Not to mention the fact that the indoor lighting revolution hadn't occurred yet. So in retrospect, do you wish you'd kept some clones around?

From imported lots of thia i had one that was collected from with in thialand by a mate but all the lines were imported in just like in the us and other places.

The diffrence was here we can grow them out doors were we are.

Back then you did not need to keep clones if you had seeds of a given line you knew what the smoke from that seed would be before you grew it out thats what i call pure and stable.

You guys can make every excuse you like fact is the older growers that infact did grow lots of diffrent pure sativas know what im saying is fact.

Green, you type in an extremely agressive manner. You may want to consider toning things down a little.

How did you grow them? Greenhouses I assume? When would they finish? How many thai plants did you grow out?

Will you share some thoughts on your experience? Does anything on the market today remind you of it?


have any of you guys tryed Nirvanas new seeds,,,,Traverling Thai etc???,,,MAU AT NIRVANA has also just started selling Cambodian too, i think its very interesting

we still have loads of Thai stick in the UK,,,,i even got a batch called Chocolate Thai a few months ago,,,,,they were the best fat sticks ive had in years,,,,i was happy smoking the Thai next to Cheese,,,,an thats weird for me,,,im a hybrid smoker,,,lol,,:)

ive still got loads of Thai stick seeds especialy from the choco batch,,,,,my friend cracked a coupple just to see them in veg,,,the never reached flower tho

Hempy,

I believe threshold effect and penetrance may likely be coming into play regarding your observations, or lack thereof. You may be somewhere where temperature or photoperiod (for example) thresholds may not have been reached, resulting in lower penetrance, where as I might be observing something else with the same genotype. In other words, the same exact plants that you observed no intersexed tendencies with may have been simultaneously throwing balls galore mid-way through flower in Northern California.

lc00p4,

I think you've maybe got your definitions of monoecious and dioecious reversed. Anyway, I think I would be tempted to term most drug strain cannabis subdioecious.

with hempy being in australia im sure he had no trouble growing out some thai, and he wouldnt need a green house, check out the climate he comes from , half of australia is in the tropical belt .
Many of us aussies grew thai , and very successfully i m ight add .

I don't know who he is or where he grew them...that's why I asked. I'm sure the bush is a great place to be growing some fine cannabis.

When you self a female (hopefully using hormones so you can use a true female with no intersex genes) S1 of XX obviously gives all XX.

If you're crossing a female to a male why would you say S1? Obviously you're not selfing her.


I think YOU are wrong Green!

What Charles posted is NOT 3 lines of continuous breeding, it is 3 SEPARATE pieces of information.

#1. Female = XX (can't argue with that)
#2. Female S1 = XX (no Y chromosome because it only has copies of it's own chromosomes)
#3. Female S1 x Male = XX x XY (50% Female, 50% Male)

Female S1 x Male is exactly what it says; it is a Female S1 crossed with a MALE.

If you take a Female S1 (XX chromosomes) and cross it with a regular MALE (XY chromosomes), you get 50% female and 50% male. That is all he said.

You ASSUMED Charles was taking the S1 listed on the 2nd line, reversing it, calling it a male and then crossing it with another S1 to create line 3, that is NOT what he wrote.

What is an fIBL? What is and fIL? I still don't understand why you don't use the accepted terms used for breeding. It will really simplify confusion.

As far as RSCS....I don't know. I'm mostly under the impression that true landrace seeds are a thing of the past. We live in the information age where world travel is more prevalent than ever. What makes a landrace is segregation from the other cannabis populations of the world. But these days everyone can get some skunk seeds. I imagine it's infinitely more difficult to get your hands on landrace seeds than it used to be. How do you know some growers a few miles away from a plot aren't growing skunk and contaminating the pool with pollen?

Besides all that, what's the point of moving back to landraces anyway? Credible, competent breeders have done everything your talking about 20-30 years ago? If you want to make improvements to the cannabis genepool it makes more sense to use the improvements that have been made in the last few decades. Why try to pretend the last 30 years haven't happened? Why not build upon people like Sam's work?

btw-Sam has said the lineage of Haze many many times. I recommend you go back and read his old posts. He's also the one who told me that the reason thai has so many hermies is because the growers of the region were selecting for sensi...

yeh thats how i see it too,,,,,,,,Charles is chatting about totaly seperate cosses

S1 x Male = M/F 50/50,,,,,,"Canna terms"

f1 X Male = M/F 50/50,,,,,,,"Biology terms"


both are actualy the same thing,,,,
