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 ...

The genetic improvement of banana and plantain has focused on breeding for resistance to black sigatoka. This has been quite successful, but the distribution of improved hybrids has been impeded by the outbvreak of Banana streak virus (BSV). Integration of viral sequences in Musa genomes make it ...

The majority of edible bananas (Musa L.) are triploid (2n = 3x = 33) cultivars known as dessert, plantain, or cooking bananas with predominant AAA, AAB, and ABB genomes, justifying the aim of breeding programs to develop improved hybrids of the different utilization classes in the triploid backgr...

Musa spp (bananas and plantains) constitute a hybrid-polyploid complex and are classified according to different genome compositions such as AA, BB, AB, AAA, AAB, ABB, AAAA, ABBB, AAAB and AABB. Knowledge of ploidy and exact genome compositions of the parental material is essential for Musa breed...

Fifteen AFLP primer pairs (EcoRI+3 and MseI+3) and 60 10-mer RAPD primers were used to detect polymorphisms and assess genetic relationships in a sample of 25 plantains from diverse parts of Western and Central Africa. The discriminatory power of the AFLP technique was greater than that of the RA...

Cytological studies in Musa spp. L. are hampered by the small size and poor staining ability of the chromosomes. The aim of this experiment was to use silver nitrate as a staining agent for Musa chromosomes. The results of this study showed that silver nitrate is a useful alternative stain for cy...

Plantains (Musa spp. AAB) are regarded as the most diverse subgroup of the triploid bananas. Initially they were classified on the basis of morphological characters. New molecular techniques are now being used to explain plantain diversity. Prior to this study no attempt has been made to merge mo...
