Abstract
One hundred accessions of sesame with susceptible (TC-25) and resistant check (SI-250) were screened under natural conditions during two consecutive seasons of 2013 and 2014 to identify sources of resistance against leaf roller and capsule borer (Antigastra catalaunalis Dup.) at AICRP (Sesame) centre of College of Agriculture, JNKVV, Tikamgarh (M.P.). The accessions were categorized based on 0 to 9 scoring methodology. In pooled analysis, flower damage ranged from 1.0 to 65.0 against 42.6 and 8.5% on susceptible and resistant checks, respectively, while capsules damage ranged from 0.25 to 15.0% against 9.0 and 2.0% on susceptible and resistant checks, respectively. In pooled analysis none of the accessions were found free from infestation of A. catalaunalis. Based on the cumulative scoring, thirteen accessions namely IS-355, IS-413-A, RJS-56-A, IS-58-2-A, NIC-16401-A, OLT-44, IS-425-C, SI-2670, SP-1162-B, IS-178-C, IC-14160-1, ES-110-C and resistant check SI-250 (RC) were rated as resistant. These could be a possible source of resistant and used in breeding programmes to develop resistant varieties.
