Abstract
A study was conducted at experimental farm of PC Unit, Sesame and Niger, College of Agriculture, JNKVV, Jabalpur, Madhya Pradesh, during Kharif 2021. Seventy five genotypes including resistance and susceptible checks were screened against leaf webber and capsule borer (Antigastra catalaunalis Dup.) under field conditions (natural infestation). The observations were recorded at different phonological stages viz., vegetative, flowering and capsule stage of the plant growth. Based on per cent damages at different phonological stages of plant growth, the entries were categorized in to different resistance categories. None of the screened genotypes were found free from infestation. At vegetative and flowering stage thirteen genotypes were found resistant showing plant damage less than 10 per cent, however, at capsule maturity stage nineteen genotypes were found resistant showing capsule damage less than 5 per cent. On the basis of overall performance (mean damage) at all the three stages of plant growth the entries viz., S-0644 (7.48 per cent), TKG-306 (7.48 per cent), VCR/81/NO/80/NS/972 (7.63 per cent), IC-1025-A (7.64 per cent), SI- 250 RC (7.67 per cent), NIC-8473 (7.67 per cent), BM-59, (7.69 per cent), NIC-8224-A (7.78 per cent), 75-120 (7.80 per cent), S-0351 (7.82 per cent) and NIC-8368 (7.88 per cent) were found promising against leaf webber and capsule borer and utilized in the resistance breeding programme.
