Abstract
Fifty four genotypes of sesame (Sesamum indicum L.) of varied geographic and genetic diversity from India were evaluated against the leaf webber and capsule borer Antigastra catalaunalis (Duponchel). The % plant, flower and capsule damage was observed to be from 7.94 to 54.43%, 8.67 to 45.45% and 7.73 to 32.15% respectively. During vegetative stage (30 DAS), eight genotypes viz., EC-334990, SP-1144, ES-62, SI-2192, IS-446-1-64, ES-335005, SI-250 and IS-178-C and during flowering stage (45 DAS), SI-250 and IS- 178-C were found resistant showing flower damage <10%. At capsule stage (75 DAS) none of the genotype was showing resistance. On the basis of overall performance (damage) at different stages of plant growth the genotypes viz., SI-250 (8.11%), IS-178-C (8.75%) and ES-335005 (9.97%) were found promising, and will be of use in resistance breeding programme as donors for resistance against A catalaunalis.
