The study aimed to identify the most well-adapted lentil genotype and select key physiological traits with strong performance using a randomized complete block design with three replicates. The analysis revealed highly significant differences (P < 0.001) among genotypes for biomass yield (t ha?1) at both the Debre Zeit and Akaki sub-stations. In terms of maturation, Beredu was the earliest, reaching readiness at 92 days, while Challew took a prolonged 134 days to reach its peak potential at Debre Zeit. The 42-day difference between these two genotypes highlights the significant diversity in growth rates. At Debre Zeit, the genotypes R-186 (6.76 t ha?1), Derash (6.83 t ha?1), Dz2012-Ln0050 (6.39 t ha?1), and ILL-1760 (6.89 t ha?1) had the highest biomass yields, while at Akaki, X-125-54 (6.3 t ha?1), R-186 (7.37 t ha?1), Derash (5.9 t ha?1), and Dz2012-Ln0050 (5.97 t ha?1) performed best. The highest seed yields were recorded for Derash (2.69 t ha?1), R-186 (2.74 t ha?1), and Dz2012-Ln0050 (2.83 t ha?1) at Debre Zeit, and for R-186 (3.41 t ha?1), Derash (2.71 t ha?1), and Dz2012-Ln0050 (2.82 t ha?1) at Akaki. The results indicated that 20 improved lentil genotypes, planted under warmer temperatures and increased rainfall, contributed to higher yields. Correlation coefficients among all traits were highly significant, with both positive and negative values. At the Debre Zeit station, days to 50% flowering were positively correlated with days to 50% emergence (r = 0.87). Biomass yield had the greatest positive direct effect on seed yield (r = 0.91).
