Abstract:
Rice is one of the most important cereal crop of developing countries and the staple food of about 65% of the world’s population. Most traditional rainfed rice varieties are prone to biotic and abiotic stresses. The present study was carried out at the experimental farm of ICAR Research Complex for Eastern Region, Patna, India in <em>Kharif</em> season 2017 with an objective to identify brown spot, sheath rot and bacterial leaf blight disease resistant rice genotypes under drought condition. The incidence of brown spot, sheath rot and bacterial leaf blight in paddy ranged from 6.5 to 34.0%, 4.50 to 20.0% and 4.5 to 27.5%, respectively. Among the rice genotypes, the highest severity of brown spot was recorded in Rajendra Sweta (34.0%) whereas the lowest severity was observed in DRR 42 (6.50%) followed by IR83387-B-B-27-4 (6.7%) and Swarna Shreya (6.8%). Minimum severity of sheath rot was recorded in IR83383-B-B-129-4 and DRR42 (4.5%) followed by Swarna Shreya (6.0%). In the case of bacterial leaf blight, lowest severity recorded in Swarna Shreya (4.50%) followed by IR88963-3-7-2-4(5.0%). Among the rice genotype, the minimum severity against all three diseases was observed in DRR 42, Swarna shreya, IR83387-B-B-27-4, IR83383-B-B-129-4 and IR88963-3-7-2-4. These genotypes may be further utilized as the genetic sources in multiple disease resistance rice breeding programmes.
