Assessment of antixenosis and aphids multiplication was carried out in the randomly selected genotypes of rapeseed against Lipaphis erysimi K. Selection of genotypes was based on our previous findings, categorized into different levels of resistance/susceptibility. Total of eight and six genotypes were randomly selected for antixenosis and aphid’s multiplication test from the pool of different levels of resistance/susceptibility. In antixenosis test, ‘G9’ (16.9) and ‘G29’ (5.7) proved to be highly susceptible, while ‘G28’ highly resistant (3.8) (1.7) in terms of mean number of aphids per flower and mean number of aphids per pod, respectively. ‘G9’ proved to be highly susceptible (21.4) while ‘G28’ proved to be highly resistant (5.5) out of eight tested genotypes in mean number of total aphids per accession. In aphid multiplication test, genotype ‘G9’ produced maximum number of offspring (93.8) while ‘G7’ produced minimum number of aphids (61.2) as compared to other tested genotypes.
