Old fox bought it to my attention that STS was first made for cucurbits.
How do gynoecious cucumber varieties differ from other varieties?
Gynoecious varieties are special hybrids which produce predominantly female flowers. Seeds of a standard monoecious variety are commonly included in the seed packet to ensure adequate pollination. (The seeds of the monoecious variety may be dyed or placed in a separate packet.) Gynoecious varieties often outproduce standard varieties when a pollenizer (monoecious variety) is present.

Complete Guide To Using STS To Create Feminized Seeds

Have a look through these articles, it might help out with a few questions you will have. The pollen you get from a reversed female will (98%-99% of the time) make feminized seeds if used on itself or another female plant, because the reversed female only has the fem chromosomes XX.
True males have the XY chromosomes.

Sex determination systems in plants have evolved many times from hermaphroditic ancestors (including monoecious plants with separate male and female flowers on the same individual), and sex chromosome systems have arisen several times in flowering plant evolution. Consistent with theoretical...

Looks like study night! thank youOld fox bought it to my attention that STS was first made for cucurbits.
Cucumbers and other vine crops are monoecious. Monoecious plants have separate male and female flowers on the same plant. Male and female flowers are similar in appearance. However, the female flowers have small, immature fruits at their base. Pollen is transferred from the male to the female flowers by bees and other pollinators. When properly pollinated and fertilized, the female flowers develop into fruit. The first flowers to appear on cucumbers and other vine crops are usually male. Female flowers appear shortly thereafter.How do gynoecious cucumber varieties differ from other varieties?

Not sure what your asking ,So in nature plants cross pollinate fair enough, so it spreads from the male plant.
With STS I can have many strains? in seed and they will not fuck with each other? and the seeds will be female and same as mother plant?
is that right??
Can you have many strains ? Well you can pollinate as many strains as you want ,you can keep them together and they will produce seed without effecting the other pollinated plants.
If using fem pollen the offspring will be female ,,but if the genetics of either parent has hermies in its ancestry then there is a risk of throwbacks and hermies being passed on ,
So best using plants that you’re familiar with. Even then, hermies can still pop up.
Will the seeds be female and the same as the mother plant ?
If you cross one strain to a different strain you can expect varying phenos ,some close to either parent ,and some as a blend of both parents. Or even throwbacks to an ancestor .
If you cross the same strain to same strain ,,eg,,you reverse one blue dream and use the pollen on another blue dream the offspring will will be blue dream ,but you will get varying phenos of blue dream ,,just like if you used normal male and female plants, so the more stability the strain has the more alike the offspring will be .
If you reverse a clone and pollinate another clone from the same mother ,you are then selfing ,,,you will get varying phenos depending on how stable the mother plant is,,,if the strain is not fully stabilised ,and most fem seeds we buy are not,,then out of ten offspring you will/should find one or two just like the mother,,
Some will yield better or worse and you may be lucky to find one that is even better than the mother,,eg, better smell or better stone.

The old way they would all screw each other and then who knows what you have? Loving this STS shit!

Good luck with your studying tonight, but let's break this down to first-principles & get this really simple before you go reading any further & do your head in.....
Cannabis plants are Dioecious by nature (ie. there are male & female plants). When you buy "Regular" seeds, this is what you're getting - a mix of potentially male or potentially female plants. No way of knowing which is which until you grow them & the individual plants start showing their sex.
In nature, the male plants produce pollen from "balls/sacks" (or whatever you want to call them), which "fertilise" the females, who subsequently produce the offspring (seeds).
A fertilisation between a male & female from the same strain is called a "Genotype" & will produce offspring of the same Genotype. However, there WILL be differences in the resulting offspring (as @Sedge mentioned), which are called "Phenotypes". They may grow differently, but they are the same strain.
To recap:
Genotype - Same strain.
Phenotype - Variations within that same strain.
Are you with me so far?
Crossing/breeding between different strains with pollen from males (Genotypes) will produce offspring showing different characteristics of both parents. There's no exact science to this, so you'll often read the phrase "Pheno-hunting".
This can be done with regular seeds, or with "reversed" females. Generally, as growers, we want female-only plants,
Now... to answer your initial question:
STS (or Colloidal Silver) can be used to "reverse" a KNOWN female plant to produce "male" pollen sacks. Since the plant itself is fundamentally female, its chromosomes will be carried-over into the pollen produced.
Collect & use this pollen to fertilise another KNOWN female plant (from the same or another strain) & you'll have a very good chance of female plants from the offspring (seeds) she produces. This is what makes "Feminised" seeds.
You'll still need to "Pheno-hunt" to get the ones you want to keep. Once you have them, you can use STS to replicate them by "Selfing" with STS.
Good luck with your journey/reading tonight.

Yes I'm getting you
I love break downs, explains a lot! thanks man. this will take me weeks to learn. Mission is before winter to gain the knowledge! I love TSE and the awesome members, so glad I found this place May the force be with me! my religion is Jedi Knight!
