Abstract:

Transgenic cotton is one of the most successfully commercialized transgenic crops worldwide. In 2023, its planting area accounted for 80.4% of the global total cotton acreage, and by 2025, the adoption rate in China had reached 95%. While transgenic cotton has effectively controlled Helicoverpa armigera infestation and significantly reduced the application of chemical pesticides, the evolution of target pest resistance, ecological risks associated with changing cropping structures, and persistent public concerns regarding the environmental safety of transgenic crops have emerged as core issues constraining the high-quality development of this industry. Against this background, this paper systematically reviewed the progress of transgenic cotton breeding, industrial application, and environmental safety assessment in China over the past three decades. It summarized the diversified breeding technology systems for insect resistance, herbicide tolerance, disease resistance, stress tolerance, and quality improvement, analyzed the mechanisms of Bt resistance evolution in H. armigera and the region-specific prevention and control strategies, and evaluated the ecological risks of transgenic cotton to non-target organisms, soil microecology, and gene flow. Furthermore, in view of the current layout of cotton-growing regions and frontiers in biotechnology, this paper prospected the future directions of gene-editing breeding, long-term ecological monitoring, and refined biosafety management, aiming to provide a scientific reference for the sustainable application of transgenic cotton and the high-quality development of China's cotton industry.
