Re: Red Beards

A follow up.
 To get red bearded blue plants a good choice of parent is a red
bearded white. In most cases half of the children will be white and
half blue and all will have red beard. I use this sort of cross often.
The reduction of anthocyanin (blue & violet) is a dominant trait. The
reduction of the carotene (yellow pigment) is a recessive. As white
and blue plants both have the recessive reduction of carotene, none of
the offspring will have yellow, or in this case the pink (lycopene).
As in most cases the white with red beard has only one of the dominat
reduction of anthocyanin genes. half of the ofsring will have this and
be white, the other half won't and will be blue.

You could also cross with a pink with bright red beard but in this
case offspring would be half cerise  (redish-violet) and half would be
pink, all red beards and of course some more intense then others. This
would requir crossing one of the cerise (the one with redest beard) to
either a blue or white with red beard.

As the red beard is hard to get to be intensely coloured I would be
sure both parents have red beards and select children primarily for
intensity of beard first and secondly for form and plant
characteristics. The blue colour will come and can be selected when
I'm happy with beard colour. 

I have been working on red beards on blue flowers and this is the
approach that I'm using.
