Screening of Genotypes for Resistance Against Sarocladium oryzae Causing Sheath Rot of Rice
A field experiment was conducted to screen rice genotypes against sheath rot during kharif 2019 under natural epiphytotic conditions at the farm of Rice and Wheat Research Center, Malan. Out of one hundred eight genotypes, ten genotypes exhibited moderately susceptible reaction while ninety eight showed susceptible reaction when categorized on the basis of disease incidence whereas when these genotypes categorized on the basis of disease index, five genotypes showed resistant reaction, twenty four showed moderately resistant reaction, sixty one showed moderately susceptible reaction and eighteen genotypes showed susceptible reaction while none of the genotypes was immune in any category.
