Yellow Clivia Groups
2 May 2000
A point of great importance, which yellows are true and
which are not, we now know that all yellows or near yellows are true breeding if
paired with the right genetic partner. Bill
Morris is currently attempting to group all the known plants in to two genetic
groups. Perhaps the egroup can assist him with his quest.
The first group (Group 1) refers to the majority of
yellow plants, the origin of these plants are from Kwazulu Natal, e.g.. Howick
falls, Eshowe area. Their distinguishing characteristics are uniformly coloured
flowers and seed pods, the flowers range from light yellow to dark yellow and
peach. The seed pods can be yellow
or yellowish green, or peach in the case of Chubb’s Peach.
Clivia’s belonging to this genetic group (Group 1)
Kirstenbosch yellow and all of it’s offspring
Karkloof Yellow, probably the same plant as Howick
Kewensis strain yellows
Also all of my own yellows, all the yellows I have
from Nakamura and most of the other Clivia growers yellows, all belong in this
group, as well as Chubb’s Peach.
The second genetic group (Group 2) is very rare in
cultivation and only a few known plants belong to this group, although I do not
have concrete evidence I firmly believe that all of these plants originated from
the Eastern Cape (Former Transkei area) and this unique genetic mutation did
indeed developed in isolation from the Natal group. Plants belonging to this
group are distinguished from the first group by both the flowers and the seed
pods, the flowers can range from pale cream to deep peach, sometimes with small
red spots on the petals, these red spots may change with growing conditions from
none to numerous, the seed pods are always two coloured, the base colour being a
nice golden yellow, with a pink blush or red spots.
Please note that if one crosses a Group1 Yellow with a Group 2 Yellow all
the offspring will be orange split for both types, and in the F2 generation it
is then possible to get group1 yellows, group2 yellows, group1 split for group 2
and vise versus as well as yellows which will be group1 and group 2 combined.
This mix up in genetic material leads to confusion and the result will be that
one can not guarantee your seed to be yellow, because a lot of orange offspring
will result from such crosses. It is there for important to cross breed plants
of the same group with each other, in order to keep the strain pure.
Plants belonging to group 2 are:
Natal Yellow also known as Giddy Yellow, Jardine and
Cynthia’s Best also known as Natal Yellow A
Apple Blossom also from the Transkei
Please note that I have removed plants from this list
as was noted in the clivia news letter Volume eight, number one, the reason for
this is that we have already proved that Naude’s Peach do not belong to this
group and are stilling awaiting the results of some of the other plants.
It is very much possible that there can be a third and
even a fourth genetic group, for example Miriam’s Picotee does not seem to fit
in any one of these groups as well as Meyer’s peach and Ndwedwe Peach, which
are all probably colour variants or freaks and not mutations, only time could
