Twelve genotypes of coriander were evaluated against coriander aphid Hyadaphis coriandri (Das) during 2015-16 and 2016-17. The genotypes viz., RCr-435, RCr-436, RCr-446 and RCr-684 were categorized as least susceptible; RCr-475, RCr-480, RCr-728 and UD-856 as moderately susceptible; RCr-20, RCr-41, UD-857 and Local as highly susceptible. The days taken for 50% flowering, plant height and days to maturity positively influence the aphid incidence, whereas, umbels/plant and seeds/umbel influence it in a non-significant manner. The biochemical constituents viz., total phenol and volatile oil exhibit non-significant correlation with aphid incidence.
