Journal Article 1995

Autor: Vandenhout, H. Ortiz, R. Vuylsteke, D.R. Swennen, R. Bai, K.

Ploidy polymorphism occurs in the hybrid offspring derived from interspecific crosses between triploid plantains (Musa spp. AAB group) and diploid bananas (M. acuminata). Therefore, Musa breeders are interested in the determination of ploidy and its effects on phenotypic expression of quantitativ...

Virus-like symptoms (due to banana streak virus, cucumber mosaic virus, or both) have been observed in plants of Musa hybrids (TMPx) and local landraces included in multilocational trials in sub-Saharan Africa. Virus-like symptom incidence in these multilocational trials was analyzed using the ad...

Black sigatoka is a leaf spot disease on plantain and banana. Its sausal agent is the fungus Mycos-phaerella fijunsis Morelet. Black sigatoka is one of the most important constraints of plantain and banana cultivation throughout the world. Yield loss can be up to 50 %. Chemical control of the dis...

Plantain and banana (Musa spp.) are integral components of the farming systems in the humid forest and mid-altitude ecologies of sub-saharan Africa. They provide more than 25% of the carbohydrates for approximately 70 million people in the region. Major constraints to plantain and banana producti...

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...

Plantain-derived tetraploid hybrids are routinely crossed In Musa breeding programmes with diploid Musa accessions for the efficient generation of putative triploid hybrid seed. However, natural open pollination of these same tetraploid hybrids also consistently generates viable seed. The mean ge...

Plantains and bananas (Musa spp. L.) are inter- or intraspecific triploid hybrids derived from crosses between M. acuminata Colla. (A genome) and M. balbisiana Colla. (B genome). Cultivars have been assigned to different taxonomic groups (AA, BB, AAA, AAB, ABB, etc.) based on morphological qualit...
