Abstract

                                Five sunflower genotype tested under 10 different environments exhibited signifi- cant differences among themselves for grain and oil yield per hectare. With reference to environments also the character expression differed significantly. Variety x Exviron- ment [Linear] interaction was however non-significant. All the varieties behaved uni formly with reference to differant environments exhibiting unit regression coefficient with estimates of 5d not different from zero and thus proved stable over all the envi ronments tested In yield of grain and oil, EC. 68415 was the most superior followed by EC 68414. On per day productivity basis however SUF. 2 proved superior over a variety of environments.
