Squid's future breeding project plans

[greenthumper]

Matt is just talking from a sheer genetics perspective. I believe he is correct in this although there is little research regarding S5+ cannabis as cres said. If I were trying to create a real strain I would use mass selection. For my personal stash though there will definitely be some selfing, I see the use of 99% female purple plants regardless of vigor

 

[The Squid]

Yeah, I figured he was talking more general genetics.

I will eventually have more mass selection. Just don't have the space to right now.

And I will be making a couple standard crosses before getting to the point of selfing it to stabalize that pheno or combo of phenos that I want.

And from what I have asked cres and he has answered. This way would create a new reputable and marketable strain.

There is a lot of luck involved with breeding from what I read too. So even though I am working with smaller numbers as opposed to the breeders that grow out dozens and even hundreds, no one could say for sure what kind of great phenos and selections I could select and use. You never really know that way. You just have to do it and see.

I think "luck" or "art" of growing is only applicable if you don't bother to learn the science. Its all probability IMO; it would be interesting to see which methods cres uses himself.

 

[The Squid]

Well that's kinda what I mean, even with the science, sometimes one can never be sure what they are about to get. Good probability is luck, haha. And yes, I am interested in how he does it too. Because there are no fems in the AFN store.

Also I wanted to add in. You can also get something you like. Self it to say S3...and then cross that with a regular non sefled plant, a male of course. And get a new strain that way. This way you're fine breeding with fem seeds because you stress tested them and selfed it with sts or cs yourself, so it should weed out most potential of being hermie that way.

Edit: Ok nevermind, I just checked. Cres is the only one with fem seeds. Or at least High Rise Seeds. It seems there are more breeders than just cres.

You will see new phenotypes in the F2 every time, guaranteed. The fact that homologous chromosomes recombine means that two parent alleles can and will produce a new phenotype. This is how "grassy, cheesy" sativa mixed with "musty, earthy" indica eventually produced "skunk" smells.

Squid I'm not telling you not to do it, just giving you a well-rounded viewpoint. I am currently in the process of selfing two clones I have, just so I can rotate/condense mothers and know I'm gonna come up with something as good or better in the seeds that I make from selfing the mother. I also am growing some of Cres' S1 mighty durban and paki x mighty durban. I just know that I won't self them again unless its a dire circumstance and I just have to keep the line pure, or if one works its way into my mother rotation, and I want to self it to save it as seed and rotate to other mothers.

I will, however, breed with it because of the advantages I mentioned about most of the traits being true breeding. Either or both will be getting some Samurai Jack x Auto Assassin male pollen within a month and a half.

"Without recombination, all alleles for those genes linked together on the same chromosome would be inherited together. Meiotic recombination allows a more independent selection between the two alleles that occupy the positions of single genes, as recombination shuffles the allele content between homologous chromosomes."

...and one more. Keep in mind that cannabis is more tolerant of inbreeding than cattle, but the same things apply. If the line gets too inbred, cross it back to one of the P1, or one of their siblings, or to one of the F1, but not back to the same individual.

" If the frequency of a deleterious allele in a population is only 0.01 (i.e., one out of every 100 alleles), and all the animals mate randomly, then only one out of every 10,000 animals would be expected to inherit the trait from both parents, and thus express the defect. But imagine that this trait is present in a particular bull, and that bull is very popular (because he also has some desirable trait, such as very long horns in the case of Texas Longhorns). As this bull is bred to many females, half of the resultant offspring would now carry any given deleterious recessive trait possessed by that bull. If these individuals are mated to one another, then 25% of their offspring would be homozygous for the deleterious allele, and another 50% would carry the allele in a heterozygous state. In this extreme form of inbreeding, in just two generations the defect went from being expressed in one out of every 10,000 animals to one out of every four animals, with three-quarters of the animals now carrying the defect. The decrease in fitness that results from such inbreeding is known as inbreeding depression."

Thanks mattinuk. I appreciate all the info, mate. I will be doing a combo of both in my breeding and like you say, if shit get's wonky, you can cross back to the original, or as lose as you can get at least.

I also am growing some of Cres' S1 mighty durban

I have already taken the Might Durban to S2, then breed it to a different Mighty Durban line for hybrid vigor.

JM is going to grow some of these this summer... Myself also.
