Black leaf streak disease (BLSD) or Black sigatoka disease of banana is very destructive and reduces yield. Most of the studies done on its pathogen Mycosphaerella fijiensis are done in the field and often influenced by natural environmental conditions. The objective of this study is to select cultivars under controlled conditions in the greenhouse. Artificial inoculation is done with a concentration of 15mg/ml of the mycelium inoculum of the pathogen and the propagator was used as a greenhouse in this experiment. The selection is made on local varieties of economic interest of dessert bananas (Adokpa, Fokona, Kaveguê, Tsikodu, Dankodu), plantains (Agbavé, Kadaga, Apim, Savé) and partially resistant controls from IITA to namely FHIA-01 and Yangambi Km 5. The inoculum is applied to the dorsal surface of the first three open leaves of each plant of each variety. The plants are evaluated at 30 days after Inoculation (DAI) and at 60 DAI. The control variety FHIA-01 is resistant, the local variety Savé is susceptible, the control variety Yangambi Km 5 and the other local varieties are partially resistant. The 15mg/ml inoculum of the mycelium and the propagator used as a greenhouse are very useful for the selection of varieties under controlled conditions. The susceptible varity Savé can be improved by stimulating its natural defense by elicitor.
