is one of a number of variegated Musa. Others mentioned in the literature
are: Musa (AAA group) Dwarf Cavendish several
un-named clones
Musa (AAB group) Aeae = Musa (AAB group)
Koae
Musa (AAB group) Vittata
Musa (AAB group) Banane panachee
Musa (AAB group) Anil Vazhai or Variegated French Plantain
Musa
basjoo 'Variegata' is mentioned in several books including those cited above.
No doubt the plant existed in the past but, at the time the books cited above were
written, I believe the plant had been lost to cultivation and that none of the authors had
actually seen it.
However,
there are now a few plants of Musa basjoo 'Variegata' in existance. How has
this come about?
Variegated
plants arise periodically when any plant is propagated. If a variegated plant arises
as a sport on a previously non-variegated plant it is almost always a chimera and this is the case in Musa basjoo. The
variegated plant arises as a bud sport on the main plant through a mutation affecting
chlorophyll production in a single cell in a shoot meristem which is eventually manifest
in the plant itself. Roughly speaking bud sports occur at the rate of 1 in
10,000. The greater the number of plants propagated the greater the chance of a
sport occuring. Bananas, among plants in general, are particularly prone to throwing
bud sports and this process seems to be further accentuated when bananas are
micropropagated. It is very common to see abnormal plants in a population of
micropropagated bananas, perhaps 1 in 2,000 or even more frequently if cultures are badly
managed. Most abnormalities are unattractive and, if plants do not spontaneously
die, plants are simply thrown away.
With
the growing market for plants for tropical effect in the garden, more and more plants of Musa
basjoo are being micropropagated. It was inevitable that sports would occur as
a result of this and some of these would be attractive variegated plants. Variegated
plants of Musa basjoo have been found in batches of micropropagated plants in
Holland and in the UK and no doubt elsewhere too. Thus, Musa basjoo
'Variegata' has been re-borne having previously been lost to cultivation.
But
has Musa basjoo 'Variegata' really be re-borne? One or two variegated
plants in a batch of micropropagated plants do not a cultivar make! It is rather
common to find variegated plants in batches of micropropagated bananas but not easy to
propagate them. Chimeras tend to be rather unstable and either revert back to the
normal green form (common) or become completely white or yellow (uncommon). This
instability makes it difficult to propagate variegated bananas even by conventional
suckers. This is the main reason that plants of the most famous variegated banana,
'Aea'e' or 'Ae Ae', are so rarely found and so expensive. The instability tends to
greater in tissue culture, which more or less precludes micropropagation from being used
for variegated bananas.
As
more and more plants of Musa basjoo and other bananas are produced through
micropropagation it is inevitable that more and more variegated forms will emerge.
Some will be green/yellow, some green/white and some green/yellow/white. Whether any
of these will be sufficiently stable to be propagated and released as commercial cultivars
remains to be seen.
