Is precociousness inherited?
« on: February 26, 2021, 07:32:42 PM »
It seems like there has been some breeding work by members of this forum with Laaz's precocious PT.  Has anyone noticed if this trait transfer's to hybrid offspring?

Attempts in China to transfer this trait from their precocious clone failed.
My hybrids of Laaz clone with 5star are 3  years old and have not flowered yet. Last year I also crossed it  with another poncirus ( SwampLemon).
Best regards,

Ilya11, subjecting your early flowering crosses once again with Laaz's early flowering PT might bring an early flowering trait.   Procimequat is both early flowering, and early fruiting.. .

Can it make a difference when Laaz's precocious Poncirus is used as female parent? I suspect it has only nucellar seeds. But there might be exceptions when the pollen comes from a vigorious variety (for instance Swingle5Star, Pumelo).

I won`t suspect F1 hybrids with the precocious Poncirus to be precocious as well. But it might be an option to backcross the F1 with prec.Pt or another precocious variety.

Concerning C.wakonai I was reported:
Our recent results here suggest that the early-flowering trait is quickly lost during a backcrossing program (backcrossing to C.reticulata), even when we try to apply high selection pressure for early-flowering.  So I suspect there are recessive allelels involved in early-flowering and it will be necessary to ensure both parents have an early-flowering parent in their pedigree.

It might be similiar with precPt.

I was wondering about if it is an option to to create an edible precocious Citrus first and cross it with precPt or Red Dwarf from Jiri. If genes for precociousness are the same in both parents it might give a chance to find a homozygous hybrid.

Exactly whaat I'm thinking, this is going to be multi-generational effort. I'm going to cross my preco-pon with poncirus+ for a better tasting poncirus base. My ponc+ hasn't even flowered yet and may not for some years.

Red Dwarf?
