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...

Musa cultivars (bananas and plantains) are important crops in the humid tropics of Africa, America and Asia. This paper reports the extent of morphological variation of the Musa germplasm maintained in the gene-bank of the International Institute of Tropical Agriculture in southeastern Nigeria. Q...

Plant breeders need to quantify additive and non-additive components of genetic variance in order to determine appropriate selection methods to improve quantitative characteristics. Hierarchical and factorial mating designs (also known as North Carolina mating designs I and II, respectively) allo...

The agronomic potential of landraces and cultivars must be determined for an optimal utilization of genetic resources in Musa improvement. Field assessment of 75 plantain landraces and 17 banana cultivars was carried out in two representative locations in Nigeria: Onne (southeastern humid lowland...

Parent–offspring regression has often been used for the estimation of breeding value and narrow-sense heritability in experimental populations, particularly for diploid species with regular disomic inheritance. With polysomic inheritance, estimates of heritability based on parent–offspring regres...
