Cauliflower is an important vegetable crop globally botanically known as Brassica oleracea var. botrytis. It is value for its edible inflorescence and nutritional properties. However, biotic stresses, including pests, pathogens, and diseases, pose significant threats to its productivity, exacerbated by changing climates and cropping systems. Breeding for resistant varieties has become imperative to mitigate yield losses and ensure food security. While traditional breeding has improved crop resilience, it is often slow and unable to keep pace with evolving challenges. For the development of tolerant cultivars to the stress, CRISPR/cas9 like advanced genome editing technology plays a crucial role. By combining traditional breeding methods with cutting-edge genomic resources and artificial intelligence, researchers can accelerate the creation of climate-resilient, high-yielding cauliflower varieties. These innovations are crucial for combating both biotic and abiotic stresses, adapting to environmental change, and ensuring a sustainable global food supply.
