A dlaczego nie s1 w femkach nie mam pojecia, nie sledze za bardzi jego poczynan od kiedy Duke Diamond od niego odbil bo to on wprowadzil swierzosc po reaktywacji
I ja nie mam pojęcia - on jest w ogóle przeciwny nasionom feminizowanym.
http://brothersgrimmseeds.com/cinderella-xx
Brothers Grimm have traditionally refused to offer feminized seeds because we didn’t believe it was necessary, and we didn’t want to risk hermaphroditism.
W takim wypadku zapewne także i hodowli z wykorzystaniem linii S.
Ciekawe ilu hodowców je wykorzystuje - Szybko można osiągnąć bardzo wysoką jednolitość roślin. Bardzo łatwo uzyskiwać z linii S bardzo jednolite F1 - masa zalet.
Nasi polscy producenci nasion?
Ciekaw jestem jak powszechnie i czy w ogóle jest to wykorzystywane.

F1 klona i C99
Our big-yielding, lime-citrus scented female clone named “Genius” due to her clear, energetic, thought-provoking high was crossed with a robust Cinderella 99 male to create Apollo Eleven.
wersja feminizowana klon x cindy 99 F1
First, we induced our favorite Cinderella 99 female, famous for resin production, to be the pollen donor for our big-yielding, lime-citrus scented female clone named Genius to create the ultimate Apollo in feminized form. We call it Apollo XX to indicate the two X-chromosomes.
Wygląda to tak jakby stawiali na hybrydy
The progeny showed variation as would any F1 hybrid, however they all reliably expressed amazing, fruity flavors and aromas – ranging from black cherry to Hawaiian punch. We decided to recreate this fantastic hybrid using our selected Cinderella 99 male, so that the masses have the chance to grow this cult classic.
IBL raczej nie tworzą - dużo backrosów w ich projektach widać.
Queen of Soul
Queen of Soul is the result of a breeding program that spanned 3 generations. Starting with our favorite Cinderella 99 female which has proven for over 15 years to create the classic flavors, high, and resin production that made C99 famous. We crossed her to an exceptional Vortex (by TGA) male, then grew hundreds of her seedlings to maturity and evaluated them. The finest male from this generation was chosen to pollinate Princess (mother of Cinderella) which created a 3-way hybrid of Princess x C99/Vortex. The resulting seedlings were grown and evaluated to select a male for a second backcross to Princess – which produced the amazing hybrid that we call “Queen of Soul.”
klon Princess jest obecny nie tylko w C99

Apologies beforehand if this is a stupid question...
So i have a single female plant of unknown strain, as im unable to acquire seeds in my situ atm i want to self this plant to itself through its clones.
My question is, doing this, will there be much, if any diversity/dif pheno's in the seeds?
Thanks for any help.
weedobix napisał:i have read it's similar to making f2's
Prawda jak by nie patrzeć. Pojedynczy selfing to jakby F2 - z tą różnicą, że wszystkie allele pochodzą z jednej rośliny.
Tak to przeglądam sobie i wygląda na to, że nikt nie planuje robienia homozygotycznych linii S4-S5 w celu otrzymywania z nich jednolitych F1. Dziwne.
a jednak: Coś tam jakby ... ale ....

Then from this 4 way picked two very different but similar expressions from the girls, and reversed them each to each other and each to itself to make 4 lines. aa ab ba bb
Then selfed the ones from each line that fit different criteria, until all the four lines true breed for a trait then re combine to add vigour and present the traits picked in higher %.
is this sound logic?

Self-Pollinating (Selfing)
“Clone Only” Varieties
Often, 2 hybrid plants are crossed and the “variety” is given a name, but soon the male plant is lost, and the plant is available only as a clone. In this case the plant must be “selfed” to produce male flowers on a female plant. Self-pollinating (aka selfing) is the process of creating seed by pollinating a plant with its own pollen. Self-pollinating is a plant having sex with itself. Self-crossing can derive populations of plants from a single individual.
The first generation population derived from selfing an individual is called the S1 population. An individual from S1 that is selfed again is called S2. Subsequent generations derived in the same manner are denoted S3, S4, etc.
Traits for which the plant is homozygous remain homozygous upon selfing, whereas heterozygous loci segregate and may demonstrate novel expressions of these characters.
We know homozygous loci remain homozygous in future generations upon selfing. Heterozygous loci are increased by 50 percent. Every subsequent generation will be 50 percent more homozygous than the parent from which it was derived.
Repeated selfing, or single-seed descent, is the fastest way to achieve homozygosity within a group or family. The more plants grown from a selfed population, the better probability a breeder has of finding selfed progeny that show all the desired traits.
Self-Pollinating Breeding
Step One: Identify superior genotypes for the trait under selection.
Step Two: Cross superior genotypes and select improved progeny.
Step Three: Repeat steps One and Two over a series of generations.

Selfing
Definition - What does Selfing mean?
Selfing is the ability of a plant, or the intentional coordination of environment to achieve selfing, to produce seeds without being pollinated by another plant or requiring another plant for any part of seed production.
Plants that can “self” are hermaphroditic plants that self-pollinate. A selfed plant will produce male and female flowers, but its progeny may not be true to form or express all of the desired traits of the mother.
Without homozygous alleles, the offspring of a selfed plant will display a diversity of phenotypes based on the recessive or dominant nature of the genes.
Hydrolife explains Selfing
Plants that undergo selfing cannot produce male only plants; they create female only and hermaphroditic seeds. This makes the prospect of future crosses or hybridization problematic. The female plants resulting from selfing may also carry the hermaphroditic trait.
Selfing is generally only a helpful practice to breeders when the desired traits of the mother plant happen to be homozygous, otherwise, at best, 75 per cent of the wanted attributes will be present in the offspring’s phenotype.
A criticism of selfing as a propagation method is owed to its diminishing returns. Many growers claim a loss of vigor with successive generations of selfed plants.
