Path coefficients were worked out in linseed varieties for sodic soil as well as for normal soil conditions to determine the true components of a complex character like yield. Path coefficients revealed that days to 50% flowering and plant height had the maximum direct effect on yield under sodic soil conditions but plant height had negative direct effect on yield in normal soil conditions. In sodic soil conditions tiller number/plant and capsule number/plant exerted a negative direct effect on yield but influenced the yield via days to 50% flowering and 100 seed weight. The positive correlation between 100 seed weight and yield in sodic soil conditions was mainly due to its indirect effect via plant height, tiller number/plant, capsule number/plant and days to maturity. Days to maturity had high and negative direct effect on yield under both the soil conditions.
