Abstract:
Two hundred two rice genotypes were phenotyped under the field (Retanga, Khordha) conditions during kharif, 2020. Based on the observation of screening, the genotypes were categorised as highly resistant (HR), resistant (R), moderately resistant (MR), moderately susceptible (MS), susceptible (S) and highly susceptible (HS). Results revealed that, among the 202 rice genotypes screened, 50 genotypes recorded a damage score of ‘0’ and rated as highly resistant. Whereas, 20 rice genotypes were noted under resistant category (Score-1). Twenty five genotypes were recorded under moderately resistant category (Score-3). In moderately susceptible category 36 genotypes recorded a damage score of 5. Thirty nine genotypes were recorded under susceptible category (Score-7). While rest 32 rice genotypes including susceptible check TN1 recorded a damage score of 9 and were grouped under highly susceptible category. Highly resistant and resistant rice genotypes can be used as a resistance source for future research work.
