Despite considerable efforts of Musa improvement programmes, banana and plantain production still depends upon a limited number of landraces selected by man from the natural germplasm. Inability to replace land-races by cultivars obtained through cross-breeding creates the increased risk of epide...
The triploid nature of plantain and its pattern of inheritance should have represented a challenge and an incentive for geneticists. However, few genetic and cytological investigations have been done in Musa spp. Both banana and plantain have been ignored and neglected as material for basic genet...
Clonal propagation of fruits, flowers, and forest trees leads to high levels of heterozygosity, fixes favorable combinations of traits, eliminates undesirable deleterious effects, allows easy identification, propagation of favorable mutations, and is an efficient method for in vitro and ex vitro ...

The basic concepts of the genetic improvement of beans through hybridization are described. In general, the breeding process involves the following phases: (1) development of exptl. lines, (2) evaluation of exptl. lines and identification of new cv., and (3) commercialization of new cv. The main ...

Cassava, yam, and plantain are staple food crops essential to food security in the humid and Sub-humid tropics of Africa. However, these crops have long growth cycles, high perishability and slow multiplication rates of propagation materials, and they are subject to a number of biological stresse...
