The aim of the work was to study the genetic origin of the persistence of male bracts and neutral flowers in diploid bananas bred by crossing diploids and tetraploids. The genetic system proposed for somaclonal variation and evolution in triploid bananas is described. [L'objectif du travail a con...

A multilocational evaluation trial comprising 18 Musa genotypes was carried out from 1991 to 1994 in three representative locations in the humid forest (Onne, Nigeria and M'Balmayo, Cameroon) and the Forest-savanna Transstion (Ibadan, Nigeria) Zones of West and Central Africa. The main objective ...

Apical dominance, i.e., the inhibition of lateral bud growth due to growth substances released by the terminal bud, has been considered as a limiting factor for the perennial productivity of plantains (Musa spp., AAB group).Segregation ratios in F1and F2plantain–banana hybrids suggest that inheri...

Plantain (Musa spp., AAB group) cultivation is threatened by black sigatoka, an airborne fungal (Mycosphaerella fijiensis Morelet) leaf spot disease. Several traits in plantains and bananas are mainly affected by major genes. The host resistance response to black sigatoka is under the control of ...
