To clarify the effects of genotype-by-environment interaction (GEI) and to develop high-yielding, cold-tolerant lentil lines suitable for cold rainfed conditions, a two-year study was conducted across four locations in Iran: Maragheh, Ardabil, Zanjan, and Kurdistan. Nine lentil landraces and one promising line (Pardis) were evaluated alongside the check varieties Bilehsavar and Sana using a randomized complete block design with three replications. Each plot consisted of four rows, each four meters long. The results indicated that the main effects of environment (E), genotype (G), and their interaction (GEI) were highly significant. Parametric and non-parametric stability analyses, together with GGE biplot analysis, were employed to interpret GEI patterns. The GGE biplot showed that the first two principal components explained 52.2% and 29.4% of the total variation in grain yield, respectively. Mean comparisons revealed that genotype G3 produced the highest average yield (781.5 kg/ha), followed by G5 (762.5 kg/ha). Genotype G10 achieved an average yield of 704.4 kg/ha, representing a 43% yield advantage over the check variety Bilehsavar and 6% over Sana. Overall, G3 and G5 emerged as the most promising genotypes, exhibiting superior performance across multiple evaluation methods. These findings underscore the importance of employing a multifaceted approach to genotype evaluation, enabling breeders to make informed decisions that enhance resilience and productivity in cold, dryland lentil production systems.
