Help with breeding

Howdy good folks

I want to try and produce my own feminized seed. I already know how to make the seed, what I need help with is genetics...
So ive got several strains from overseas and want to use them to produce seed. Say for example, I want to produce fem seeds of gelato. Is it best to use the fem pollen from one female and pollinate a different plant of the same strain or is it best to pollinate the same plant that i too the pollen from? Would the resulting seed give consistently similar plants or would i be "degrading" the genetics? How many times is it possible to repeat this process from the offspring until i start getting crap seed?

I strongly recommend you check out the breeding information already posted. Here's the Breeder's Laboratory sub-forum.


IAANPC (I am a newbie pollen chucker), so take what I say with a bag of salt.



Creating the pollen from one plant, then pollinating a clone of the same plant will create S1's. The results will vary, depending on which plant you're using. Yes, a larger number of the plants will resemble the original plant.


Many feminized seed offerings are the product of one reversed female, used to pollinate a different female plant. Some of the higher quality breeders use several similar females (which takes a lot of time/resources to find), and cross them to several other prime examples of a different strain.


Waiting to see whether a cross is good or not sure takes a long time. lol

For creating fem seeds

Step1
Aquire a reversal spray (please post a link as I want to buy some pre made myself),, clear (no bits) cordial silver of a high ppm is essential

Step 2
Find 2 plants of decent tolerance to environmental reversals,,, this is so your progeny won't reverse without a reversal spray

Step 3

Aquire polen from a donor plant



At this point you ditch the donor,,,

You then have xx chromosome polen,, now you can dust a stress tested plant with confidence

When you do an outcross,, you get a limited number of phenotype expressions,,, if you incross you limit the scope of the genotype but recombination can give rise to quite a variety of phenotype expressions

When we go to s2 or s3 we start radicly increasing the inbreeding coefficients,, this is what breeders do to "fix traits" into a seedline,, backcrossing is also used to fix traits

So there you go,, any questions?,, just ask

Just to be clear the gametes are all X. because gametes are haploid, the pollen is usually either X or Y the Ovum in the calyx is always X, it's by making sure all the pollen is X that makes the seed XX but the second X comes from the seedparent not the pollen.

Those are pretty open ended goals...

What are you trying to accomplish?

Selection is extremely important.
