Screening of Some Fungi Isolation of Rice Cultivars in Different Site of Allahabad, Varanasi, Mirzapur, Jaunpur and Chandauli District in Uttar Pradesh

Abstract

Rice (Oryza sativa L.) one of the staple food crops of 60% of world's population, suffers from different kinds of diseases caused by fungi. In the present study, five paddy samples were collected from different places of Allahabad, Varanasi, Mirzapur, Jaunpur and Chaundali District of Uttar Pradesh, in India and screened for fungal pathogens using Potato Dextrose Agar plate method. Results showed varied Disease Incidence in collected samples ranging from 56.66% to 83.33%. The variety "BPT-5204" collected from Allahabad showed a minimum DI of 56.66% whereas "Basmati-370" collected from Jaunpur showed 83.33% of maximum of total DI, followed by "Narendra-59" from Mirzapur 80%, "Sonam" from Chandauli which showed 73.33% DI and "Rupali" collected from Varanasi which showed 63.33% DI. Highest fungus frequency was recorded in rice variety Basmati-370 and lowest fungus frequency was found in BPT-5204. Seven fungal species namely Penicillium, Helminthosporium sp, Fusarium sp., Aspergillus niger; Aspergillus ochraceus, Altrnaria sp., and Aspergillus clavatus in all the five samples have been recorded.
