Ruderalis contamination discussion

Hey Id like to hear what you guys think, I have grown CBD rich strains in the last couple few years and I have found from breeding with them that some of them pass on the auto flowering gene.

I think anyone serious about breeding should always know the exact lineage because as time goes on, we are going to endup with auto-flowering genes in all the strains!!

For instance, I used a Respect female in several projects now, the offspring always do fine its when I take it down to F2 that I am seeing problems. If you look at the lineage of Respect, there is one of those ''unknown sativa'' and I believe it to be ruderalis.

I am not 100% sure about the strains I made using the Respect yet but I have had the same problem trying to grow any seeds I made using a male Revolution from the same seed company. After sexing my plants I cannot put them back in the veg room without them going into full flowering mode. Most of their strains are CBD rich hence ruderalis contaminated... am I right?

I am afraid a lot of breeders are taking the ruderalis short cut when it comes to creating CBD rich strain ... only assumption at this point but please share whatever you think or know on the topic!

YOu might want to think about backcrossing before these results....

I would think that you are at the ultimate expression of un stability in a majority of F2's....you now are combining recessive traits that showed, if any, from the F1....or at least you had a better chance too...

Being cbd rich imho is not an idictment of ruderalis genetics....backcrossing would clear up alot of whether your particular cultivars are truly homozygous for cbd production or just expressing heterogenity in only that f2 generation....that is the danger without a good long breeding history over a few generation at least.....

In fact, I am of the opinion that all cultivars [strains] have the genomic capability for not only the autoflowering trait, but also the self sexing trait aka hermaphroditism. The guy who did all the epidemiology work on cannabis in the 60's [Rahm Das? ] made mention of this in that particular paper....

Also to add to this, in terms of speciation and botanical classification: Ruderalis is being considered as simply as variety of Cannabis Indica, just like Sativa, instead of its own species....So the science community is still on a 20 year argument over whether ruderalis in fact, Exists.

Another antecdotal example [because I have not completed testing yet...] is from pheno's I get from a alien Og/ Kush line I have been working....One pheno exhibits some Cbg/Cbn/Cbc/Cbd qualities, with all the phenotypic traits of the other "pheno"....yet, the THC content of the 1st pheno is significantly [at least I am assuming from head change/ terp smell/ etc...] less, if not altogether void..
Neither exhibit autoflowering traits as of yet...and I have worked these two for around 24 months, off and on.....

I would strongly hesitate to say that the sole progenitor of cbd genes, comes from ruderalis strains.....the background for that, just isn't in the literature that I am aware of at the moment...however, that may change and make me look like silly shit too...

Thanks for contributing! I am not saying that ruderalis is the sole progenitor of cbd genes, but I am affraid they are used as a ''short cut'' to get high cbd strains as opposed to selective breeding, which would take too long for the current high demand for CBD strains. You are right that I should not worry so much about it.

Unfortunately, I think all of my high cbd strains have some ruderalis because ultimately, they are all descending from la reina madre and juanita lagrimosa (http://en.seedfinder.eu/strain-info/Sra_Amparo/Reggae_Seeds/ , I believe the unkown sativa is a ruderalis)

At any rate, I have a lot of seeds to go through right now, I do grow a lot of my seeds 12/12 from seed and to have the autoflowering gene in the mix would really affect my yields.

I have used a gas chromatography kit a long time ago, so I have seen and experienced totally different highs from 2 different phenos of pennywise. I know now that I dont necessarily want super high CBD and low THC I want high THC and medium CBD.

I know my breeding is all over the place right now, I am not breeding for stability but for pheno hunting... once in a while I do back cross when I find something special but sometimes its not possible.
