Cottonseed, Gossypium hirsutum L., production and quality are affected by agronomic practices, cultivar differences, and environmental conditions. Experiments were conducted to compare the quality of seeds produced from six cultivars. Cotton was grown in experimental plots at Mississippi State, MS. At harvest, bolls were collected from selected positions on fruiting branches of the plants. After ginning, seed was collected for evaluation. Quality of the seed was determined by seed weight, kernel weight, size and color, microbial content, oil content, and free fatty acid (FFA) content of the oil. For all cultivars, yield and quality were highest in bolls adjacent to the main stem on branches in the center of the plant. Statistical analysis indicated that seed yield, seed and kernel weight, and oil content exhibited a significant (p < 0.05) cultivar by fruiting site interaction. FFA and microbial content were significantly (p < 0.05) different among cultivars and fruiting sites.
