ABSTRACT

Two wild and five mutant isolates of Gliocladium virens were tested for morphological and
physiological characterization. On PDA and OMA media all the isolates produced usual green
coloured fluffy or submerged colonies with profuse mycelial growth except 50 Gv1V, which
showed albino colour colonies. 50 Gv1I isolate produced comparatively large size ampuliform
phialides whereas larger phialospore was produced by Gv1 isolates. All the isolates grew more
rapidly on PDA than OMA medium. Irrespective of isolates, high sporulation was observed both
in OMA and PDA with few exceptions. In case of biomass production the PDB medium was
found superior to other media. The mutant isolates 50 Gv1V produced higher biomass on the
basis of mycelial dry weight (293.00 mg) on PDB whereas on CDB highest mycelial growth
(174. 67 mg) was recorded with 50 Gv1I isolate.
