How does one create a feminized line?

[africaseeds]

I've heard people talking about creating and working a feminised line.
How would that work. Would you start with feminized pollen from one strain and spray it on a completely different clone and then grow out those seeds and self a plant and keep in breeding it?

What are limitations on a feminized line and could one theoretically create a feminized IBL?

I don't mean how to feminize seeds. I know how to do that. I meant how to do line work with fems? Like how do I go from S1 to S2 to maybe S3 and can I even make an IBL from a feminised line?

exactly as you say take a female and reverse... grow seeds. select and self or cross to other female. or can take fem pollen hit a different variety grow out the seeds and then use pollen to Back cross to original mom

yes can stabilize for traits much faster. yes can cross to other females.. however you do loose some vigor, ace for example says it can be upwards of 20% BUT may be worth it vs getting 20% of plants that do not have your desired traits..

instant gratification and good way to "hold" an elite plants traits, but you will always have better vigor with regular seeds.. plus you will loose genetic diversity.

IBL isn't nessasarily a good thing with fems ore regs for that matter. depends on your goals. To take that and cross to another stable plant to make a true F1 and have that awesome vigor and select a mom from those offspring with whatever % of mom or dad u prefer. the greatest varietys are hybrids! blue berry, Afghan Thai Mexican, SSH, OG kush (Thai Pakistani etc), super silver haze, Skunk (afghan mex columbian). perhaps DJs and Sams line a great example. made a cross to make F1s then only selected from that gene pool.

IBL means something that is "true breeding" so I don't think u can use IBL if using fems, more so BX 5 or so times.

if have access to African varietys make regs along with your fems if you must!

saying S1 sorta infers what needs to be done, so your question is rhetorical. its like saying how do I walk 3 blocks west? wellll u walk west for 3 blocks

Best thing to do is have a goal! what are you looking to achieve in your project? make copies of a special mom? or make a novel variety? for SOG or SCROG? keep starting from seeds or find an awesome mom to keep from your breeding? flavour speed etc..

Oregon cbd only uses fem for breeding and they make the best cbd/cbg seeds on the market

They did an interview saying that males just took up time for them and was not really needed. There lines are ibl

Thanks for all the replies!

Might want to read up on the limitations of femmed plants and breeding. After a few generations of fem only breeding, you can run across problematic genetic issues. If I recall, it's somewhere around S5'ish?

What generation of fem x fem are the seeds you're starting with?

>>What generation of fem x fem are the seeds you're starting with?
All S1's. Was just curious though about how far you can take it. I'm curious to know what the scientific reason would be that there would be genetic issues after S5, but I'm sure there isn't much research on that yet. Thanks for the info.

When you read up on it, you'll find there's been quite a lot of research done. Though I have no links, I've run across breeders with the issue many times in the last 15+ years. The basics are, you're skipping part of the full DNA mix when you use only females. After too many generations you get problems.

Breeding back to a male, every few generations, can prevent this from happening.
