Default Variegated Hop Question.

(Oops sorry for posting this in the "What is this nut tree?" thread)

I have an old male Hop (Humulus Lupulus) from which late in the
season has budded out a variegated shoot (direct from rhizome).

The first two pictures are of a rooted cutting of the shoot.

The third picture is another cutting taken later from that cutting which
I took because of the strange mosaic variegation and odd leaf shape
on this bine (note that only five variegated leaves are showing in this
image as other leaves are from older 'normal' hops growing in the same
area.)

Both of these plants are now about 1M height (they will soon die back
for winter) and will produce small rhizomes. When I grow them both
up to maturity next year and use the pollen to fertilise some of my Hop
cultivars, Goldings, Tettnanger, etc. Will they transfer this trait to
some of the seeds?

Was hoping to produce a variegated ornamental female hop

Variegated plants are often chimaeras. If this is the case the variegation
won't pass through the pollen. (Depending on which genotype contributes to
the pollen you may pass the trait for the variant leaf colour onto
seedlings; this may well be recessive, but could be made homozygous by
backcrossing to the variegated plant. (Any homozygous plant may be weak due
to low/absent chlorophyll.)

But the above is not always the case. You can but try.

Thanks for that information Stewart, its good to know it's not a total
impossibility. It will be fun to try this next season.

Rupert.
