摘要：
Twenty two elite Indica rice genotypes were evaluated for resistance against blast disease under induced artificial epiphytotic conditions. Screening of rice genotypes for blast resistance was based on disease severity (%) and AUDPC parameters. The disease severity (%) and AUDPC was less than 46% and 1000, respectively in all the resistant genotypes, while it was more than 46% and higher than 1000 in the case of susceptible genotypes. Substantial variability was observed among rice genotypes for resistance to Magnaporthe oryzae. Thirteen rice genotypes expressed resistance against the blast disease and the rest nine rice genotypes were observed susceptible under artificial epiphytotic conditions.
