 ABSTRACT

Agro-morphological characterization of genotypes under extreme environmental conditions is important for understanding functional diversity and productive potential of crops. In this study, four maize genotypes (Zea mays L.) were evaluated in the Sahelian context under two water regimes: stressed and optimal using a split-plot design with four repetitions and two factors (genotype, water regime). Our results showed significant differences between the genotypes for several agro morphological traits. The principal component analysis of the thirteen traits that were measured revealed that the first two components explain 95.25% and 95.95% of the total variation for optimal and water stress conditions respectively. In addition, our results showed that eight of the thirteen studied traits contribute the most to discriminating the four genotypes under both crop conditions.
