Study of Genetic Improvement and Susceptibility in Relation to the Infestations of the Leaf Roller and Capsule Borer Antigastra catalaunalis (Duponchel)

One hundred twenty nine accession of sesame with susceptible (TC-25) and resistance check (SI-250) were screened under natural infestation condition during two consecutive seasons 2019 2020 to identify the source against leaf roller capsule borer (Antigastra catalaunalis Dup.) at AICRP on oilseeds center JNKVV, College Agriculture, Tikamgarh (M.P.). The categorized as highly resistant (HR), (R), moderately (MR), (S) (HS) based cumulative score (0-9) grade (1-9) individual accsession. Among 131 viz., In pooled analysis, damage ranged from 0.0 40.0 per cent checks, Flower 29.6 15.85 1.3 checks , respectively, while capsules 17.15 3.05 0.4 % respectively. analysis none found free A. catalaunalis. Based scoring ,twenty one namely EC-334961-1, Annand local, IS-653-A, NIL-16426, IC-14331, NIC-8282, IS-387, G-13, EC-334955, NIC-8062, G-8, SI-1925, EC-35000, G-19, IS-90, GRT-83138, EC-303423-C, NIC-17362-A, ES-310420, IS-178-C, SI-250 forty S-0481, ES-75, TILO/Hana, EC-335001-A, S-003116, NIC-16114-B, BS-61, EC-164966, KMR-90, EC-335003, IS-722-2-84-I, NIC-17477-I, 43994, Oct.-81, Ec-182832, NIC-8033, G-2, G-6, NIC-9835, IS-77, GRT-8327, S-0619, ES-131-I-84, IC-152485, IS-449, IS-150-3-84, ES-64, IC-30884 ,GRT-8359, S-0281, IS-712, GRT-83128, NIC-16218, KJS-21, NIC-14730, Juland Sahame, SI-1865-1-B, GSM-21, IS-346, S-01159-C, GRT-8336. With check, SI -250 (RC) rated these could be a possible used in breeding programs develop varieties. These germplasm lines might exploited hybridization for development cultivars.
