The triploid genome of plantain (Musa spp., AA group) has been considered intractable to genetic improvement because of the production of putatively homogeneous 2n (= 3.r) gametes. Plantain breeding schemes have been based on the hybridization of 2n megaspores from the triploid plantain and haplo...

Progress in the breeding of plantain and banana has been restricted by the complex genetic structure and behaviour of cultivated polyploid Musa. Genetic improvement has been hindered due to the large amount of space required for growth and maintenance of plant populations, in addition to the long...

Molecular genetic techniques may have a wide range of applications for improving the efficiency of Musa breeding and conservation. These range from analysis of genetic behaviour and structure, germplasm characterization and marker assisted selection. Restriction fragment length polymorphism (RFLP...

Genetic diversity amongst 76 plantain landraces has been studied using RAPD analysis at two levels of intensity and compared with groupings based on phenotypic indices and morphotype. There was a good correlation (R2=0.78) between estimates of genetic diversity based on 76 RAPD bands and 164 RAPD...
