Screening of sesame genotypes/cultivars against major insect pests

Abstract

The investigations on the screening of sesame genotypes/cultivars against major insect pestswas carried out at the College farm, College of Agriculture, N.A.U., Bharuch during 2020-21. Out of 10 genotypes/cultivars of sesame screened for their relative resistance against major insect pests, the genotype/cultivar GTil 6 and GTil 10 were found resistant against jassid, Orosius albicinctus Distantand whitefly, Bemisia tabaci Gennadius. Cultivar GTil 10 were found resistant against leaf webber, Antigastra catalaunalis Duponchel and Bemisia tabaci while, AT 413 and G Til 4 were found moderately resistant against Orosius albicinctus and Bemisia tabaci. Genotypes AT 413 and AT 437 were found moderately resistant against Antigastra catalaunalis. Significant maximum yield was recorded in cultivars G Til 10 (488.30 kg/ha) whereas, minimum yield was observed from genotype AT 409 (151.07 kg/ha).
