Abstract:
Forty three mustard genotypes/varieties were tested against the mustard aphid Lipaphis erysimi (Kalt.) under natural field condition at the College of Agriculture and Research Station, Raigarh during Rabi season of the years 2013-14 and 2014-15. The result showed that the 6 moderately susceptible and 37 susceptible genotypes /varieties had aphid infestation. Generally, aphid infestation showed trend from flowering stage, reached the peck at pod formation stage, and then trend to the decline in all the genotypes/varieties.
