The relative resistance or susceptibility of nearly 215 rice genotypes supplied by Indian Institute of Rice Research, Hyderabad was screened to identify the resistant genotype against rice yellow stem borer. The trial was conducted following augmented block design with two checks ., local check (BPT 5204) and susceptible check (TN1) for a period of two successive kharif seasons (2016 & 2017). The per cent incidence of stem borer was recorded at their peak infestation of dead hearts at tillering stage and white ears at reproductive stage. The status of the screened genotypes was determined by following the standard evaluation scale (SES) for stem borer as suggested by IRRI. | Identification of rice genotypes for resistance against yellow stem borer in irrigated rice
