• The demographic pressure in Benin has led to an increase in demand for cereals, in particular maize ( Zea mays L.), which constitutes the staple diet for the populations. Yet, in this context of climatic variability, the environmental conditions greatly limit the yields of this crop. The purpose of this study was to compare the agro-morphological characteristics of nine (09) local and improved varieties of maize ( Zea mays L.) by screening the most efficient and promising varieties which better meet the agro-ecological conditions of the district of Djidja (southern Benin). To more control sol homogeneity, semi-Latin square design with three repetitions was used as experimental design during the trial. Twelve agro-morphological characters selected from the maize descriptors were used to compare the varieties. The results showed that the agro-morphological characteristics varied significantly depending on the varieties studied except for the emergence rate. The improved variety IWD SYN W was the best tolerant variety to climate change for cultivation in the municipality of Djidja comparatively to the other eight varieties. These results can directly support the maize productivity programs in southern Benin.
