In the present investigation, 20 mustard varieties, along with one check variety, were screened for resistance against mustard aphid infestation. The results categorized 2 varieties as highly resistant, 10 varieties as resistant, and 8 as moderately resistant. Aphid-infested plants exhibited a significant reduction in chlorophyll content, indicating a decline in photosynthetic efficiency. Furthermore, varieties with higher concentrations of secondary metabolites, such as total phenols, proteins, and glucosinolates, showed lower aphid incidence, suggesting their role in enhancing resistance.
