The stability analysis in seven genotypes for six characters viz. Days to flowering, plant height, number of umbles per plant, number of umblets per umbel, number of seeds per umblet and seed yield per plot of coriander grown from 1980–81 through 1982–83 (rabi) was performed and the presence of GxE interactions was revealed. The linear component was important for seed yield, days to flowering, plant height and number of umblets per umble. Thus the performance of genotypes over environments for these attributes could be predicted. Non linear component was important for number of umbles per plant and number of seeds per umblet, thus making these characters unpredictable. Genotype Pco-4 was most adaptable showing highest seed yield above average response and nonsignificant deviations from regression.
