Abstract
Mustard cultivation, a vital aspect of agriculture in India, faces significant challenges due to the infestation of Lipaphis erysimi, commonly known as the mustard aphid. This study aimed to assess the in-vitro multiplication of aphids across various mustard cultivars during the 2019-20 rabi season. A total of 45 cultivars were evaluated using a completely randomized design (CRD) with three replications. The aphid multiplication index was calculated by aphid multiplication index method, and cultivars were classified based on their resistance to L. erysimi. Results revealed a range of responses among cultivars. Two cultivars, Aravali and RP-9, classified as highly resistant, had the lowest aphid multiplication index values. The resistant category included three cultivars Durgamani, RH-406, and RVM-2. Thirty-seven cultivars were identified as moderately resistant. Three cultivars, YSH-406, Rohini, and NC-1, were found to be moderately sensitive.
