The objectives of this study were to; i) identify farmers’ cropping systems, production constraints, and farmers' preferences for traits improvement using the 1000Minds decision-making tool, ii) assess phenotypic and genotypic diversity among locally cultivated and introduced yam germplasm, iii) identify genomic regions associated with useful agronomic traits using Single-Nucleotide Polymorphic (SNP) markers and assess the effect of genotype by environment interaction of useful agronomic traits in selected yam genotypes.
