Chemical composition of Bt cotton fiber and seed oils: Influence of agro-climatic conditions on growth and yield
Author(s): Mei Huang and Zhenyu Wang
Abstract: Bacillus thuringiensis (Bt) cotton has revolutionized cotton cultivation across multiple continents by reducing bollworm-related crop losses and enhancing yield stability. While agronomic outcomes have been extensively documented, less emphasis has been placed on the biochemical characterization of Bt cotton products particularly fiber and seed oils and how these are influenced by agro-climatic conditions. This paper examines the chemical composition of Bt cotton fiber and seed oil, with a focus on cellulose, lignin, and wax content in fiber, alongside fatty acid profiles, gossypol levels, and minor bioactive compounds in seed oil. Cross-regional analysis across diverse agro-climatic zones (India, China, Brazil, South Africa, and the United States) highlights variations in growth, yield, and biochemical characteristics. Findings reveal that favorable irrigated and subtropical zones consistently yield fiber with higher cellulose percentages and seed oil rich in linoleic and oleic acids, whereas drought-prone or saline environments alter fatty acid balance, increase gossypol, and reduce overall yield. The results underscore the importance of integrating biochemical profiling with agronomic assessments to optimize Bt cotton’s contribution to textile and food industries.
