Parents, F 1 , F 2 , and backcross generations (BC 1 and BC 2 ) of a cross of safflower, Carthamus tinctorius L., were planted at two locations in Iran (Safiabad and Ahvaz). Data were collected on yield/plant, heads/plant, seeds/head, seed weight, flowering time, and height. Location effects were either significant or highly significant for all traits except for heads/plant. Generation differences were either significant or highly significant for all traits except for heads/plant and seeds/head. Location ✕ generation interaction was significant only for seed weight. Genetic analysis of the generation means were carried out at each of the two locations for those traits that showed significant differences among generaions. Dominance played a major role in the variation of yield/plant and seeds/head at Safiabad. For the remaining traits at either location, in addition to different degrees of additive and dominance effects, significant interallelic interactions were obtained. The full model analysis for seed weight showed, in addition to highly significant additive and dominance effects, a highly significant additive ✕ location interaction. Dominance ✕ location was not significant for seed weight
