Researchers tested 288 mungbean varieties across three farming regions in Benin to find which ones produce the most grain reliably, even as growing conditions vary — pinpointing top performers that could anchor food-secure, protein-rich cropping systems in West Africa.
288 mungbean genotypes evaluated across three agro-ecological zones in Benin showed significant genetic variability and genotype × environment interactions for all 13 traits measured.
Grain yield exhibited low broad-sense heritability, indicating that environmental conditions — not just genetics — are a dominant driver of how much a variety produces.
Three statistical methods (AMMI, WAASB, and MGIDI) were combined to identify the most stable, high-yielding genotypes, offering a multi-trait selection shortlist for breeding programs.
