This study assessed
the ability to yield the intraclonally cross-pollinated seeds of clones
Honduras (HON) and Cameroon (CAM) from Musa
(M. balbisiana) and
THA018-THA, Calcutta4 (CAL), Microcarpa (MIC), Zebrina (ZEB) and Truncata (TRU)
from Musa acuminata (M. acuminata).
Ten variables were measured. Anova and two-sample Student’s t and Z tests were
applied. Results shown that M. acuminata
differ in M. balbisiana. The latter
is more vigourous and productive in seeds than the former. Clones HON and CAM
expressed the highest values of vegetative and seeds yielding in fruit. They
might be used, not only in the conservation of genetic resources of banana in
the form of seeds in laboratory, but also in hybridisation programme.
Nonetheless, in hybrids dedicated to trade, such ability to yield seeds must be
eliminated by successives back crosses in the view to releasing edible fruit.
In clone HON, the distal hand is more productive in seeds than the medium and
proximal ones. In contrast, in clone THA, all the three positions yield the
same number of seeds. Their uses must take into account such particularity.
