Feminised F1 hybrids both ways

[El Timbo]

Out of interested has anyone tried making F1 fem hybrids both ways with the same 2 female plants? i.e., A x B and B x A - and if so did you observe any differences in the progeny?

I just posted this in cbd breeding but think it is applicable because you are describing a type of reciprocal cross.

with no males though

Not tried it, but in theory, you should see differences. Not from the DNA but the mtdna

Ace is offering both Malawi x Panama and Panama x Malawi fem F1s.

I can see the MxP fems but no PxM fems...

Could you explain this theory please?

I have crossed reversed pre-98 bubba with White Rhino, and may soon be in a position to cross reversed WR with pre-98 bubba.
I'll keep you posted

Could you explain this theory please?

not an expert but mitichondrial DNA is inherited from the mother.

Ok thanks - the PxM fem is no longer available but they do talk about differences in the progeny. There are different Malawis in each cross though...

Indeed!I had forgotten it,just was the first example that came to mind!

Dubi from Ace somewhere has mentioned about the difference in breeding his Zamal x Hashplant fem cross trying either way and alternate results in progeny...I'll try to find the piece.

Exactly, the mtdna is responsible for the ATP, so the most vigorous female should always be the mother in a fem cross.

Are you sure? Always? And you say you've never tried it? I get nervous when people start using the always word

 

[GMT]

I did also use the should word lol.
But unless there are issues like mixed sex flower sets, I would always say yes, always. Of course if there are issues with either plant, it should not be used as either parent.

Would this apply only to the vigour trait?What about potency for example?

Why do you say always use the most vigorous of the 2 as the mother? To what end?
