Abstract
This experiment was executed at College of Horticulture, Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.) during 2019-21. This experiment was conducted to estimate the variation present among the isolates of Myrothecium roridum causing leaf spot of bael against leaf spot of bael. The fungus produces branched aseptate and greenish mycelia, conidiophores & mycelium were branched, aseptate, greenish & conidia were hyaline. Conidiophores were branching twice or thrice, and each branch gave rise to almost two to five phialides in whorls. Among all the five isolates, isolate Mr2 (6.12 & 2.16m) had the smallest length and width & Mr5 (7.80 & 3.45m) had the longest, according to the mean.
