Kenaf is a common wild crop of tropical and subtropical Africa and Asia with numerous applications. However, it required optimal water for growth and yields which may be a constraint in tropical areas. This study aims to investigate the biochemical response of ten kenaf varieties to water stress to develop drought-tolerant kenaf. Ten kenaf varieties (Ifeken 400, Ifeken 100, Cuba 108, Au-72, Tianung, Vi-100, A60-282, AC-313, Au-754, and Au-2452) were planted n=5 in a pot of soil in a completely randomised block design. They were arranged and divided into five groups according to the days of watering (WR10, WR8, WR6, WR4). WR10 (watered on every tenth day), WR8 (watered every eight days), WR6 (watered every six days), WR4 (watered every four days), while the control received water as required. The plants were later harvested at maturity (110 DAP); Compatible solutes (soluble protein, soluble carbohydrate and proline), lipid peroxidation, and ascorbic acid, photosynthetic pigments (chlorophyll a, b and carotenoid), and antioxidant enzymes (SOD, POD and catalase) were examined. Data were analysed using anova at (P≤0.05). The results showed that among the ten varieties of kenaf examined, Ifeken 400, Ifeken 100, Tianung and Cuba 108 showed the highest values in all the biochemical parameters, which indicates that these varieties could be tolerant to water stress and could be useful in an area with little or no rainfall.
