Abstract:

The present study was conducted at the experimental farm of ICAR Research Complex for Eastern Region, Patna, India in Kharif season 2016 with an objective to identify false smut resistance rice genotypes. False smut (Ustilaginoidea virens (Cooke) Takahashi) is of serious concern to the rice growers as it affects rice quality and significantly reduces the yield particularly in irrigated ecosystem. Twenty one genotypes were evaluated for their resistance and susceptibility to the disease under in-situ conditions. Significant differences were observed for resistance to false smut disease among genotypes. Four rice genotypes Swarna Shreya, IR96321-1447-521-B-2-1-2, IR96321-1447-651-B-1-1-2, and IR 83294-66-2-2-3-2 were immune or highly resistant against false smut. Maximum per cent infected panicles and the number of smut balls per panicle were observed in genotype Sabbhagi Dhan (65.00%) followed by IR96321-1099-227-B-3-1-3 (55.00%). The resistance genotypes may be further utilized as the genetic sources in disease resistance rice breeding programme.
