out of interest, why cant you give rep out or edit posts?


and waht are your views on epigenetics? you didnt respond to that issue.

i wonder what charlesX thinks about Reverced Backcrossing

i think Reverced Backcrossing might stop Genetic drift or allelic drift

I think I'd do an outcross, then F2 the F1s, then make selections of male and females that most closely fit the clone, to make F3s, then backcross to the clone, then inbreed that line. It would be far simpler and would result in a line that didnt need to be outcrossed in order to be of use.

Have a nice day...

wow you told me. but the thing is thats not all hes doing. duhhhhhhhhhhhhhhhhhhhhhhhhhhhh hes creating hermies to bx back to a hermie...
i dont really care if you have a nice day.


i cant believe you said that Heavy D,,,,,,your talking some serious crap with that reply to col

your not grasping the undrestaning behind my ideas if you think im using hermi polen

an the Reverced Backross method is only a method to stop "genetic drift",,,,if it wont work to stop generic drift il give-up the idea,,,,,,

but i am convinced Reverced Backcrossing will be the perfect way to "RESET" the sequence of allene back to its perfect state,,,,if genetic dift takes its tole




i guess you have 1 valid point if you think sex revercal alters DNA an this alters inheritance factors....but still,,,where is your evidence,,,i have my reference points to say DNA is not affected by sex revercal ,,,,

YOU are going against years of testing bro,,not ME

Due to the effects of epigenetics, you may have trouble identifying the correct offspring to use as the phenotypes expressed in the offspring may well not be indicative of their natural state if such stress had not been present in the life of their parents.

Hm.. seems like a good route plan.

I want to have 2 ibl parent plants to create f1's, so if i ever decide to make other ibls, i can whack either of my "cheese" ibl parents with what ever i want to in the future.


2 f2 fathers, 2 selected S1 females. both selected through test crossing for seed tests.

Cross one with the other, Choose seperate males from each seed batch, bx f2xs1 into the cheese, take the 2 seperate [f2xs1]xCheese lines, Choose both lines to be skunky, but with their own little quirks, take to f8 - f10, Once both lines have the stablity i want, test cross fathers and females from each line into each other, take notes of whos pollenated who, grow out produced seeds, find which batch of seeds have the desired charecteristics set out for at the begging of it all, use the 2 parents to produce ma seed.

also id like to see what either of my parent ibls would do say crossed into the ibls already popping up, such as the SourD.

Hi again,

In my opinion it should look more like - if A, then B, if C, then D. Pretty tough to plan as far ahead as all that not knowing how it's going to go. Avenues may end up in dead-ends, backing up may be necessary. In GMT's hypothetical, we outcross right away, what will that tell us? Not much maybe. Then we go as far as f3, then backcross to the original clone - a clone we know little about due to the path chosen. The backcross at that point may in fact be a step backwards. Then inbreed from 4 gens onward? This doesn't sound simpler to me at all.

On the other hand, if we begin by selfing the original clone, this will tell us plenty. If the offspring is all over the board, then we know backcrossing to it after f3 would maybe not have been the wisest choice. Selfing the clone seems a very logical first step in my opinion regardless of the direction from there.

I'd like to respond to this thread, but:

A) reading it hurts my brain... likely because...

B) there is so much nonsense on these pages that I don't even know here to begin.


It's not that I don't like you Rick, I don't know you... but I do think you post alot of nonsense about topics you don't understand, which leads to more confusion as people read your words and might not realize that you really don't understand what you are talking about.

I've been trying to clarify many of these cannabis breeding topics on the internet for over 10 years.... and really these threads make me feel like all that work, all those explanations was for naught!

Have you read any breeding texts? Marijuana Botany? Allard's Principles of Plant
Breeding?

I wrote a small, simple chapter for Jorge Cervantes' Medical Bible that I think might clarify some of your basic assumptions re: breeding cannabis. I would recommend you search that out, read it a couple of times and then get back on your path to enlightenment. Maybe armed with the basics you could then approach Allard's work, or many other excellent writtend works on plant breeding.

Good luck in your search,

indeed it is hard to plan so far ahead, but a planned path could help ease out afew things.

im just looking for strong smells and a growth pattern, so selection is by eye and nose, plus stress testing ect..

Hopefully with huge quantitys of seeds grown for each generation, the real true beautys will show,

btw im not a breeder at all, just a guy with a very imaginative mind.
