In addition to seed quantity, study of seed quality of crop in conditions of competition could be profitable for seed procurement from field. For this purpose, produced seeds of four wheat cultivars (Sayson, Alvand, Chamran and Sepahan) in interference with deferent densities of feral rye (0, 20, 40, 60 and 80 plants m-2) were harvested. In laboratory, of each field unit, 50 number of wheat seeds separated and placed in petridish for germination test. Results showed that by increasing feral rye densities, reduced grain yield, 1000-seed weight, percent and coefficient of uniformity germination, plumule length, radical length, radical dry weight, radical volume and density of seeds from wheat cultivars. In contrary, increased mean germination time. At each level of weed density, minimum and maximum amount of studied traits obtained from Alvand and Sayson, respectively. Obtained correlation coefficient was indicated of robust relation between 1000-seed weight and mean germination time. Also Mean germination time showed robust relation with seedling traits. Generally, results of this study showed that seed weight from interference with weed, had significant effect on seed quality and related traits.
