Meiotic studies in Musa L. have been hampered by: 1) time-consuming efforts required to find the correct stages of cell division; 2) rigidity of the microsporocyte cell wall that makes preparation of smears difficult; and 3) poor staining of prophase chromosomes. This study describes an improved ...

Cooking bananas (Musa spp., ABB genome) were intro-duced into Southeastern Nigeria by the International Institute of Tropical Agriculture (IITA) in the mid-1980s as an interim measure to reduce the incidence of black sigatoka disease (caused by the fungus Mycosphaerel-la fijiensis Morelet) on pla...

Secondary triploids were produced by crossing primary tetraploids with selected diploid partners and the parthenocarpic banana (Galeo). Comparisons between secondary tetraploids and secondary triploids showed that the secondary tetraploids generally had lower yields than secondary triploids. The ...

Using the technique of random amplified polymorphic DNA (RAPD), we have identified 116 amplification products in Musa germplasm using nine primers. This has enabled us to identify RAPD markers that are specific to each of nine genotypes of Musa representing AA, AAA, AAB, ABB, and BB genomes. The ...

Leaf age effects on the leaf conductance to water vapour diffusion of the adaxial and abaxial leaf surfaces were measured in the morning and in the afternoon on 17 different plantain and banana (Musa spp.) genotypes. The irradiance levels increased three-fold while leaf to air vapour pressure def...

Breeding efforts for genetic improvement of banana and plantain have gradually shifted from individual trait selection to simultaneous improvement of several traits, following an ideotype concept. Therefore, information on the phenotypic and genetic association among these traits, and the influen...

Les efforts d'amélioration génétique du bananier et du bananier-plantain ont graduellement passé de la sélection de caractères individuels à celle simultanée de plusieurs caractères, suivant un concept d'idéotype. Ainsi, il devenu est important pour le sélectionneur Musa de connaître le degré d'a...

De grandes differences existent entre les cultivars quant a la frequence et la nature des variations phenotypiques sur les plantes regenerees apres culture in vitro. Une grande part de ces variations mime la variabilite naturelle et les variants apparaissent essentiellement comme des copies d'aut...

Plantain (Musa spp., AAB group) is a staple food crop in the humid forest regions of West and Central Africa. Its cultivation is threatened by black leaf streak (BLS), an air‐borne fungal leaf spot disease, caused by Mycosphaerella fijiensis Morelet. An on‐farm survey for BLS severity in relation...

The triploid genome of plantain (Musa spp., AA group) has been considered intractable to genetic improvement because of the production of putatively homogeneous 2n (= 3.r) gametes. Plantain breeding schemes have been based on the hybridization of 2n megaspores from the triploid plantain and haplo...

Bunch orientation is an economically important trait in plantain ( Musa spp. AAB group) and banana ( Musa spp. AAA or ABB groups). Pendulous bunches are more symmetrical than subhorizontal, horizontal, or erect bunches and are, therefore, better adapted for transportation. Erect, horizontal, subh...
