Blight resistance refers to the ability of plants to withstand or recover from blight, a type of disease caused by pathogens like fungi or bacteria. This resistance is crucial for maintaining healthy crops and ensuring food security, as blight can lead to significant yield losses. Breeding programs often focus on developing varieties of plants that exhibit blight resistance traits. Farmers and agricultural scientists utilize various methods to enhance blight resistance, including selective breeding and genetic modification. By incorporating genes from naturally resistant plants, they can create new varieties that are better equipped to handle blight. This approach helps reduce the reliance on chemical treatments and promotes sustainable farming practices.
