The production of Brassica crops, which include economically important species like broccoli, cabbage, and rapeseed, has transformed tremendously from ancient times to contemporary biotechnology innovations. Through history, these crops were cultivated for their nutritional and medicinal properties, with the earliest traces found in ancient Egyptian, Greek, and Roman cultures. The conventional agricultural practices, such as rain-fed cultivation, broadcasting by hand, and organic manuring, formed the basis of environmentally friendly practices. The Green Revolution (1960s–1980s) turned the tide with the introduction of HYVs, chemical inputs, and mechanization, dramatically increasing productivity. Yet, these developments also created environmental issues, such as soil degradation and misuse of pesticides. The latter half of the twentieth and early twenty-first centuries were marked by revolutionary biotechnology advances in the form of hybridization, genetic engineering, and tissue culture, which led to increased disease resistance and stress tolerance in Brassica crops. Recent emphasis is on precision agriculture, using CRISPR-Cas9 genome editing for genes such as drought resistance and AI-based tools for maximized resource utilization. Climate-resilient measures such as no-till agriculture and biofertilizers, coupled with sustainable water management practices, are mitigating the impact of climate change. The future points to the use of nanotechnology for targeted application of agrochemicals, robotics for efficient farm management, and genomic selection for enhanced crops. They are meant to align production with ecological balance, stabilizing food amidst global uncertainty.
