Genotyping the local banana landrace groups of East Africa por Karamura, D., Kitavi, M., Nyine, M., Ochola, D., Ocimati, W., Muhangi, S., Talengera, D., Karamura, E.B.

“…Seven diploid landraces originally from Tanzania, 37 triploid landraces (24 East African highland bananas (EAHB); 5 'Ilalyi' (AAA genome), and 8 ill-defined types from Tanzania), 6 exotic triploids, and 3 exotic diploids originally from the International Transit Center were genotyped with simple sequence repeat (SSR) markers. This study sought to understand the genetic relationship between the EAHB and the diploid landraces and other banana groups (local triploid landraces, and introduced (exotic) cultivars) so as to decide whether to include the diploids in the breeding scheme of EAHB. …”
