The study on the propagation of banana seedlings took place in Lwami in the Cirunga area, Kabare territory. The aim was to improve banana production in South Kivu in general. The rapid multiplication of bulbs in the macro propagator as the sampling method experimentation coupled with observations in the field. The multiplication rate in situ was 15.5 for dessert banana (FHIA 23 variety), 6.4 for plantain (FHIA 21 variety) and 5.3 cooking banana (FHIA 17) compared to the beer banana (CHIBULULA variety) which multiplication rate was 1. In the field cultivation, FHIA 21 and FHIA 23 have a large size and offspring than CHIBULULA and FHIA 17 but they are no difference into FHIA 21 and FHIA 23 according number of offspring and l size.  Again, the number of banana leaves emitted and banana pseudostem heights of those varieties are the same in ex situ cultivation. The multiplication of banana seedlings is an asset in the middle of South Kivu to have the suckers quickly exempt from diseases. This work recommends the Agriculture Inspectorate to make the banana offspring available to farmers, allowing them to multiply this crop.
