Phenotypic stability of the yield components of three sunflower (Helianthus annum L) inbred lines in their third, fourth and fifth year of self-pollination was analyzed. Stability parameters were calculated following an Eberhart and Russell (1966) model. According to regression coefficients, the investigated lines showed satisfactory stability of the protein content in seeds and weight per 1000 seeds. The line D4441 in the third year of self-pollination was identified as the most stabile one regarding protein content. As for weight per 1000 seeds, the best genotype stability was detected in the line Rs 4 I 10 in its fourth year of self-pollination.
