Abstract
The common bean (Phaseolus vulgaris L.) is one of the main legumes produced and consumed in the Central African Republic (CAR). But in CAR, the common bean production is constrained by certain biotic and abiotic stress which severely impacts the quantity and quality available in the value chain. To compensate this loss of the production, the Central African Institute for Agronomic Research (ICRA) had introduced in CAR ten varieties of common bean from Rwanda and Cameroon. A four-repeat randomized full-block device was used for testing the performances of these ten varieties of common bean. The measured variables were the vegetative growth, the production, and the sensibility to plant diseases. Overall, the different varieties exhibited a high germination rate (88.6%). The highest rate is observed in variety RWR2245 from Rwanda (100%). Varieties from Rwanda, RWR3194 with 1000 kg ha-1 and BOA5M1-6 with 916.66 kg ha-1 gave better yields followed by varieties Ecapan 025 from Cameroon with 833.33 kg ha-1 and RWR2245 with 833.33 kg ha-1. The yields obtained are roughly referred to the agronomical standard. The varieties NITOU and NUA566 from Rwanda were more susceptible to disease incidence and pest attacks compared to those from Cameroon.
