Breeding techniques
People keep asking me questions relating to breeding techniques (teks). It's an important subject worthy of a special thread. There are a number of useful breeders on the forum, this could be educational for us all.

Could we start with inbreeding? I think this is most important to all collectors and breeders alike. I personally am thinking with my "MR NICE" Early Queens growing all seeds and doing an open pollenation for seed stock. Is this a wise decision for the common grower/breeder to do with a pack of your seeds?

this should be a great thread Nevil. let hope people use there search to find the section.;) lets start with something simple though. that way everyone can read something practical to them from the start and it can get technical later for the more advanced breeders. i think it will be easier for everyone to follow this way instead off novice breeders getting lost in the fort few posts & having to ask question over and over again. thank for this thread i think it will be really useful for people. its like a early Christmas present i like lots would off payed for this info in a book.:)

1:1 matings is something I'd like to address. People suggest that I'm creating a bottleneck and it's true. A bottleneck of quality. Seeds are usually produced by using two parents. With a 1:1 mating you know which ones they were.

As a seed breeder, the job as I see it is to ensure that the customer has the highest chance of producing a keeper pheno, whilst at the same time keeping the median a high standard. Every packet should produce top shelf plants. These guys who say you have to buy numerous packets of seed to get a keeper, crack me up. The job is not to save the gene pool, but to satisfy the guy who gave you the money. Few people want to give you money to save the genepool (but I am taking donations) Haha!
If I'm making Early Skunk and the mother EP has been chosen. Which Skunk male fathers the seeds does make a difference. Single progeny tested males is your best guarantee of quality and crop uniformity.

Really? Wow. Just simply wow.

So who's job is it, other than the people who propagate the species, to protect this incredibly valuable genetic resource?

Stunned Nevil, really.

just interested but what can we do to protect the gene pool other than make crosses? it may not be the job but by making a cross arnt you protecting the genetics

i got a q when i find that perfect male, how can a keep him with out pollinating everything by mistake, do small carbon filters filter pollen???

While the individual genes may live on, unique gene combinations are lost with every successive 1:1 or low N population breeding scheme.

The only real preservation strategy, and responsible step (in the sense of preservation) is to open pollinate as many individuals from the original population as possible.

From there selections can be made and used for any other type of breeding scheme be it hybridization or within-line breeding, but the original pool, and all the alleles available in the initial population are still available for further selection in the future.

Most of the original unique populations (landraces or ancestral cultivars) have unfortunately been extremely bottle-necked and many valuable alleles have been eliminated, because the early breeders who worked with the species didn' realize that cannabis is an outcrosser and has different breeding requirements than most flower species.

Outside of you actually believe you are hurting the gene pool?

Great thread idea!
I'll be following this thread carefully.

P.S occasionally I might ask the odd dumb question or two. ;)
