Screening of indigenous rice genotypes of Manipur for their resistance reaction against rice yellow stem borer

Abstract

Different local Manipuri rice genotypes were screened out to find their resistance reaction against rice yellow stem borer. The per cent of the incidence of stem borer ranges from 1.07 to 4.97 per cent of stem borer damage. Among the 41 local Manipuri rice genotypes screened against stem borer, Moirangphou Khokngambi (1.47 per cent stem borer damage), Chingphou (1.70 per cent stem borer damage), Tei (1.71 stem borer damage), Bungpat (1.79 per cent stem borer damage), Phouren Khoknembi (1.83 per cent stem borer damage) and Langphou (1.98 per cent stem borer damage) were recorded minimum incidence against stem borer. Whereas, Mieling Manthowean (4.53 per cent stem borer damage), Kiebiphou (4.28 per cent stem borer damage), Mashi (3.89 per cent stem borer damage), Mashi Manui (3.81 per cent stem borer damage), Tathai (3.78 per cent stem borer damage), Aso (3.72 per cent stem borer damage) and Shangao (3.72 per cent stem borer damage) recorded highest incidence of stem borer.
