Diversity of Endophytic Fungi in Banana Cultivars of Assam India

Endophytic fungal isolates (139 no.) were obtained from 143 (62 roots, 18 fruits and 54 leaves) samples of 15 different varieties banana collected 10 sites in Assam, India during 2018-2019. Overall isolation frequency surface-sterilized tissue ranged 10%-80% (as per site) 6%-70% variety banana). All segregated into 40 types on the basis macromorphological micro morphological characteristics. Forty taxa isolated belonging to 14 genera including Absidia, Arthrinium, Aspergillus, Bipolaris, Cladosporium, Curvularia, Dendrophion, Fusarium, Humicola, Mortierella, Mucor, Penicillium, Paecilomyces, Verticillium one mycelium sterile. Among them, Cladosporium cladosporioidies Paecilomyces sp. frequently occurred most surveyed whereas Cladospoirum cladosporioides Aspergillus 8, Fusarium graminseram varieties. However, all differed their diversity. Banana Narigoan Jorhat have been found with maximum species followed by marigoan so as Amrit Sagar endowed 27 no. fungi Jehaji Honda which associated a Isolation relative abundance cladosporiodes (80%, 4.6), farinosus 4.6) Penicillium ruburm, 8 & 9 (70%, 4.02) recorded comparatively sites. Mortieralla Pacilomyces are (73.33%, 4.93).
