Charcoal rot caused by Macrophomina phaseolina (Tassi) Goid is one of the most devastating diseases of sesame and causes heavy losses worldwide. The disease is becoming severe in sesame growing areas due to increased level of inoculum in soil. The pathogen of charcoal rot disease becomes more destructive particularly when high temperature and water stress conditions occur during growing period of the crop. A field experiment was carried out for two consecutive years during Kharif 2017 and 2018 at oilseed research area, CCS HAU, Hisar for identification of resistance source against charcoal rot of sesame. Host resistance is an important component of integrated disease management for charcoal rot of sesame. Among various management practices against charcoal rot, breeding for the resistant varieties is effective, economic and eco-friendly method to overcome this problem. Resistant variety ensures protection against this disease, save the time, energy and money spent on other measures of control. Three hundred and fifty (350) sesame germplasm lines were evaluated for identification of the resistance source against charcoal rot disease. Among evaluated germplasm, majority of them showed moderately susceptible and susceptible reaction whereas two lines viz., NIC-8533 and S-1671 were identified as highly susceptible against charcoal rot disease. None of the germplasm line showed complete resistance while eighteen lines viz., NIC-7837, NIC-7875, NIC-17849, SI-2174-1, SI-3296, IS-92-2, HT-9913, IS-455-A, PCU-129, PCU-136, IC-303419, HT-20, HT-9907, KMR-13, TC-159, TC-184, TC-318 and EC-303419 were identified as moderately resistant against charcoal rot of sesame. The information generated through this experiment can be utilized in horizontal resistance breeding programmes.
