Abstract:

Rice blast caused by Magnaporthe grisea is one of the most destructive diseases of rice causing significant grain yield losses. Keeping in view the importance of disease, studies were conducted on cultural and morphological characters at Indian Institute of Rice Research (IIRR), Hyderabad, Telangana. Survey was carried out to identify and characterize the fungal pathogen associated with rice blast disease in different crop growing regions of Andhra Pradesh and Telangana states. A total of 40 blast disease specimens were collected from different locations of Andhra Pradesh and Telangana and disease severity was recorded. Later the associated pathogen was isolated and identified. In pathogenic studies, considerable variation was found among the isolates. Isolates which showed excellent sporulation index-4 (RBNL 12, RBMU 37, RBPB 38, RBDR 1, RBKM 8 and RBMT 11) has also recorded high PDI (78.13-80) under artificial inoculation on HR-12. The sporulation index-1 of the isolates RBRG 20, RBTP 13 and RBND 24 was poor but they showed high PDI (70.01-80.23) on HR-12 under artificial inoculation.
