During this study, different varieties of cotton seeds from various cotton growing areas in Côte d'Ivoire were physically and biochemically characterised. These are the varieties W471B, W448C, X442B and R405-2000 (Korhogo, North), BDL and BULK-SR (Bongouanou, East), W471A and W448C (Katiola, Centre). Physically, these varieties were characterised through 8 parameters: seed index, kernel rate, hull rate, seed moisture, linter rate and healthy, damaged and aborted seed rates. Biochemically, six parameters were measured: Total phenol activity, polyphenoloxidase activity (PPO), phenylalanine activity (PAL), peroxidase activity (POD), protein content and total sugar content were evaluated. Moisture (12.32%), aborted seeds (50%), spoiled seeds (41.63%), hull (44.87%) and linter (1.32%) were higher in the east (Bongouanou). The rates of seed index (09.10%), kernel (66.65%) and healthy seeds (53.66%) and linter (1.32%) are higher in the North (Korhogo). At the biochemical level, the results of our work revealed that for the same seed varieties, when total phenol and POD activity are high, PPO activity is low and vice versa.
