Journal Article 1997

Autor: Ortiz, R. Vuylsteke, D.R.

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 ...

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 ...

Scientific strategies for crop improvement ensue from genetic knowledge gain from the relevant breeding populations. Few genetic studies were undertaken in Musa before the 1990s, despite the importance of the crop in human diet in the tropics. It was believed that genetic studies of most cultivat...

Epidermal and histological characterization of Musa species and cultivars were carried out to investigate the descriptor value of calcium oxalate between groups and subgroups of cultivars. Epidermal peels of the bracts of selected plantain and banana cultivars stained with 0.01% safranin solution...

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...

Plantains and bananas are economically important crops in many African countries where they are cultivated in compound gardens by small holders primarily for domestic consumption. These subsistence farmers generally believe that the cultural practice of removing the male buds from bearing banana ...
