Stabilizing desirable traits in heterozygous plants?

I am sure this subject has been beaten to death I have a clone of Burmaberry which I would like to make crosses with but I want to try and first work with it so that it passes on more of its desirable traits to the progeny.

I already out crossed it to another untested line, the results were volatile to say the least, from pure sativas to pure indicas and every imaginable combination in between.

I know that Burmaberry is a cross of shiksaberry #3 and a Burmese land race or at least an IBL (reeferman seeds). I believe it was a straight pollen chuck, no real breeding was done.

Obviously an IBL would have been first prize but I don't have a male. So that leaves back crossing. But I remember chimera saying that back crossing a known heterozygous plant is futile. So what options does this leave me?

I was hoping for a reply from either Tom or Chimera so it looks like its my day!


I only recently became interested in selfing so I don't know too much about it as a breeding tool. Would the technique described above hold all the benefits of a true IBL?. Is selfing like back crossing in that it leads to inbreeding depression very quickly?

If I understand you correctly I should self each subsequent generation of desirable individuals until I see the traits under selection breeding true?

Very interesting to me that a heterozygous plant can still produce homozygous individuals, with the desired traits, in its progeny. Obviously this is why it is so important to select from as large a population as possible.

Tom if I have a clone and I know nothing of its history would it be advisable to cross it with a known true breeding line, to reveal its stability?

Self the clone. Grow out the S1's. Look for the Mendelian ratios that should arise in different traits.

Aa x Aa = AA,Aa, & aa @ 25%, 50%, & 25%.

Ok I get it so selfing has become a serious breeding tool!

If I use pollen from a reversed female and I out cross it to an unrelated line then will the resultant seeds still be so called 'feminized' seed?

I think I have almost enough info to get started on my breeding project. I will update in this thread!

Off to study Phenomenal's thread on making colloidal silver!

If I understand right, that has nothing to do with selfing, it's about breeding all female plants and they can be what ever progeny/line/cross you choose?

The question was: does the plant have to be self pollinated to ensure all female seeds... Or can you use that same pollen from the reversed female to pollinate unrelated plants and still get female seeds?

Are you saying no you can't?

What has nothing to do with what?

I'm sorry if I might not understand right.
Not my language this english.

What I'm trying to say, that if you pollinate female with female ( reversed ) they are going to be females, cause there is no male part in progeny..
There is only allele xx=female.
So the progeny is always females.
The pollen can come from lady itself or from some other female, some other cross/landrace too?
This is what I have understood.
