Description

This study assessed the ability to yield the intraclonally cross-pollinated seeds of clones Honduras (HON) and Cameroon (CAM) from Musa balbisiana (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.
