In South Kivu, banana occupies the first place in terms of cultivated area. Although the yield of bananas is still low, production varies between 4 and 10 tons per hectare per year. However, heavy threats from diseases and pests are currently affecting the production of bananas and plantains. Among these threats, we find bacterial wilt of banana. The aim of this study is to compare four varieties of banana for the production of rejects by the method of macro propagation in Mushweshwe. Four varieties of banana were used so, two of beer (Yangambi and Nshikazi) and two others cooking varieties (Cavendish and Gros Michel) were multiplied by the method of macro propagation. The 4 varieties combined 200 strains (cormes) at the rate of 50 units per variety. The stumps were sterilized with hot water. The results showed mother strains of the Nshikazi variety had a significantly lower mean circumference than the others, but the average number of rejects produced was not significantly different between the four varieties even if this variety Nshikazi (53 rejects) was high followed by Yangambi 35 rejects in second place, followed by Cavendish with 34 rejections and finally Gros Michel with 32 rejects. The correlation analysis between strain size and the number of weaned rejects showed that at a certain level, strain size negatively affected the production of rejects. Thus all the varieties used are good for the production of rejects. Finally, the estimate of production cost shows that the use of local equipment for the production of rejects costs less than the use of the standard unit.

In South Kivu, banana occupies the first place in terms of cultivated area. Although the yield of bananas is still low, production varies between 4 and 10 tons per hectare per year. However, heavy threats from diseases and pests are currently affecting the production of bananas and plantains. Among these threats, we find bacterial wilt of banana. The aim of this study is to compare four varieties of banana for the production of rejects by the method of macro propagation in Mushweshwe. Four varieties of banana were used so, two of beer (Yangambi and Nshikazi) and two others cooking varieties (Cavendish and Gros Michel) were multiplied by the method of macro propagation. The 4 varieties combined 200 strains (cormes) at the rate of 50 units per variety. The stumps were sterilized with hot water.

Abstract: (french)
Au Sud-Kivu, le bananier occupe la première place en termes de la superficie cultivée. Bien que le rendement des bananiers y soit encore faible, la production varie entre 4 et 10 tonnes à l’hectare par an. Cependant, de lourdes menaces dues aux maladies et ravageurs pèsent actuellement sur la production de la banane et des bananes plantains. Parmi ces menaces, nous trouvons le flétrissement bactérien de bananiers. L’objectif de cette étude était de comparer quatre variétés de bananiers pour la production de rejets par la méthode de macro propagation à Mushweshwe. Quatre variétés de bananiers ont été utilisées dont, deux à bière (Yangambi et Nshikazi) et deux autres variétés à table ou à cuire (Cavendish et Gros Michel) étaient multipliés par la méthode de macro propagation. Les 4 variétés réunissaient 200 souches (Cormes) à raison de 50 unités par variété. Les souches étaient stérilisées à l’eau chaude. Les résultats ont montré que les souches mères de la variété Nshikazi avaient une circonférence moyenne significativement inférieure à celle des autres mais le nombre moyen de rejets produits n’était pas significativement différents entre les quatre variétés même si ceux de cette variété Nshikazi (53 rejets) était élevé suivi de Yangambi 35 rejets en deuxième position, suivi de Cavendish avec 34 rejets et enfin Gros Michelavec32 rejets. L’analyse de corrélation entre la grosseur de souches et le nombre de rejets sevrés a montré qu’à un certain niveau, la grosseur de souche affecte négativement la production de rejets. Ainsi toutes les variétés utilisées sont bonnes pour la production de rejets. En fin, l’estimation de coût de production montre que l’utilisation de matériels locaux pour la production de rejets coûte moins cher que l’utilisation de l’unité standard.
