dominant traits, dom cultivars..?

Just like to start a thread that may help folks choose cultivars to breed. Having an idea of if and what will get passed down of course is super helpful.

1. i can say that seems to be dominant in crosses. is of course "blueberry". being ibl anything hit with blueberry, the "berry" always seems to come through. 1 reason there is so many crosses of it.

snow lotus, black domina?? skunk#!

feel free list what dominant cultivars or dom traits from those cultivars that seem to come through more often then not. As in some cases great to have a cultivar that lends structure or frost without adding different smell or taste to the cross.

peace

deep chunk seems to dominate !..........a part of me kinda likes Polly hybrid pollen chucks ............ for the diversity of specimens ........... and f2s of course

C99 goes both ways... Dom in some cases & allowing the other parent to shine in others.

It seems to add frost most of the time.

If you do breeding blocks/squares or whatever it's called, it's 25% chance for either parent. Either the parent's offspring pheno's have dominant or recessive traits that show up.

It takes large crop numbers to see all the genetic possibilities. So it's 25% chance for any single trait. I don't know how many traits cannabis has.

Last time I grew a Bubba cross only 1 of the 6 females plants had any resemblance flavor/odor wise. I'm having much better luck with the Bubba leaner's children though
 
What you are talking about is creating a "gene list".

I've been wanting to do this for ages so let's get it going.

Let's focus on a gene list, as a "dominant cultivar list" would provide too narrow a field of selection, in fact, would only provide those looking to make their own hybrids with a P1 that is already in everything and used by everyone.

With a gene list, we could create a living document.

This can definitely be done, especially with the immense amount of information/documentation on a forum like ICMag and with the help of researchers like Jason Sawler of DAL U, who co-authored The Genetic Structure of Marijuana and Hemp.

Where the authors mentioned some very interesting findings:

For example we found that Jamaican Lambs Bread (100% reported C. sativa) was nearly identical (IBS = 0.98) to a reported 100% C. indica strain from Afghanistan. Sample mix-up cannot be excluded as a potential reason for these discrepancies, but a similar level of misclassification was found in strains obtained from Dutch coffee shops based on chemical composition [10]. The inaccuracy of reported ancestry in marijuana likely stems from the predominantly clandestine nature of Cannabis growing and breeding over the past century. Recognizing this, marijuana strains sold for medical use are often referred to as Sativa or Indica “dominant” to describe their morphological characteristics and therapeutic effects [10]. Our results suggest that the reported ancestry of some of the most common marijuana strains only partially captures their true ancestry.

and continued...

In contrast to other clonally propagated crops like apples and grapes, however, strain names are assigned to marijuana plants even if grown from seed. Thus, a marijuana strain name does not necessarily represent a genetically unique variety.

We've been confusing what genes really are for too long. Genetics are not "sativa nor indica dominant" That's an over simplification, and it needs to stop.
Both "species" share the same genes, so a gene list would help anybody select a plant that expresses the recessive or dominant traits they need, regardless of it's claimed ancestry or name.

Humans share 99% of our DNA with chimpanzees but we are hardly the same, so comparing genes between indica and sativa means very little when you consider how small a percentage difference in genetics can drastically change an organisms morphology.

Creating a gene list is OK in theory, but how do you propose we start this gene list? Do you know of a specific Cannabis gene in which all the possible alleles have already been documented for functional expression, relative dominance, and their existence or absence in specific strains or cultivars?

yea phylos is def a great start aswell as far as genes which eventually may help figuring out what gene does what and in what combo. sucks that we all dont have sequencers and all we can do is go off our observations :)

would be great to get solid amount of info from what folks have observed from at home "breeding" or seed saving.

Cheers!
