Plantain and banana (Musa spp. L.) polyploid hybrids have been obtained after interspecific hybridisation and ploidy manipulations (i.e., interploidy crosses). The identification of promising hybrids for cultivar release requires their field testing to assess agronomic performance. The potential ...

Crop growth and damage parameters (plant growth and yield, root damage and nematode population densities), believed to be associated with resistance of Musa genotypes to nematodes under field conditions, were evaluated in a field trial of 24 Musa genotypes inoculated at planting with a combinatio...

Reproductive growth in polyarchic Musa spp. varieties occurs by the simultaneous growth of several shoots, resulting in competitive inhibition of fruit development in the individual shoots, particularly under poor soil fertility conditions. Nine plantain genotypes were forced into single-culm gro...

Plantains (Musa spp. AAB group) are starchy bananas widely grown in Africa and tropical America by small landholders. Genetic analysis of the plantain genome is difficult due to its triploidy and high sterility. Ploidy manipulations (scaling up and down the number of chromosomes) and interspecifi...

Africa is one of the secondary centers of diversity for the genus Musa. There is a wide range of genetic diversity in the bananas found in the continent with different types dominating different ecological sub-regions. Banana production in Africa is affected by a number of diseases and pests. The...

Recent successes in the conventional cross-breeding of plantains and cooking bananas by genetic improvement programmes will inevitably lead to an increase in the number of new clones that require testing before release to farmers. In most cases testing focused on disease resistance and yield but ...

Plantains and bananas are an important staple food crop in developing countries. Genetic improvement programmes have been spurred by the rapid spread of black sigatoka disease, but the genus Musa is intractable in terms of conventional breeding strategies. The potential ofbiotechnology in banana ...

Spatial nutrient distribution was studied under a multi-species hedgerow cropping with plantain on an acid ultisol in southeastern Nigeria. The objective of this study was to evaluate variation in soil nutrients under alleys formed by multi-species hedgerows at three sampling sites: 0.5 m around ...

Micropropagated plants of 36 Musa genotypes with diverse genetic backgrounds, including 14 tetraploid plantain (TMPx) and banana (TMBx) hybrids, were evaluated for their response to banana streak badnavirus (BSV) infection under three environments from 1995 to 1997 in Nigeria. The characteristics...
