The thesis investigates phenotyping and quantitative trait loci mapping of hard-to-cook traits and yield-related traits in common bean. It presents research on evaluating a panel of locally conserved common bean accessions for agronomic and yield traits through field trials. Data was collected on traits like flowering time, maturity duration, plant architecture, and seed yields. Statistical analysis was conducted to determine genetic variability and identify correlations between traits. The research aims to identify superior lines and loci associated with important traits to support common bean breeding
