Abstract excerpt
Groundnut (Arachis hypogaea L.) productivity in Niger remains low despite its potential, mainly due to erratic rainfall, poor soil fertility, and disease and pest pressure. This study aimed to quantify the effects of genotype, environment, and genotype × environment interaction (G × E), evaluate yield performance and stability, and identify superior genotypes and optimal test environments. A total of 21 groundnut...
