Forty two genotypes of fenugreek (Trigonella foenum-graecum L.) were evaluated in normal (full irrigations) and water stress (restricted irrigations) environments for three years. The genotypic expression was influenced by the environments significantly for five morphological characters and seed yield. Simple correlations have indicated that pods per plant as the main yield component. Stability analysis indicated that high yielders in general had high ‘b’ values indicating their adaptability to normal environments and vice versa. UM-13 followed by UM-15 showed absolute stability for seed yield. AMMI analysis and GGE biplot revealed good correspondence between the spread of genotypes and environments for pods per plant and seed yield. The biplot analysis showed that RMt 1 was found to be suited to water stress conditions over the years while UM- 29 and UM-24 were the most desirable ones with high yield over all the environments.
