Online published on 23 July, 2019. Abstract Screening of 22 varieties/lines of Indian mustard (Brassica juncea L.) for their resistance to mustard aphid, Lipaphis erysimi (Kalt.) was carried out at the Department of Entomology and Agricultural Zoology, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi. The lines NDR08-14-1, NDR08-1, MCN14–33, MCN14–31, NDR1–11, MCN14–24, MCN14–23, MCN14–27, and NDR07-2 were observed with the least aphid population and thus proved to be resistant. Variety/lines NDR8501, MCN14–32, NDR-7, MCN14–25, MCN14–29 and VARUNA were observed to be moderately resistant, while NDRS 2010, DIVYA-33, MCN 14–30 were susceptible, with lines NDRS 9–2 and NDRS 2001-1 being highly susceptible. The maximum yield was obtained from the line NDR08-14-1 (13.14 q/ha) in comparison to the line NDRS2001-1 with the least yield (6.71 q/ha).
