An experiment was conducted to study the effect of pure cultures of Volvariella volvacea, raised from tissue as well as mono and multi spore cultures, on the spawn quality and mushroom yield. It was revealed that spawn prepared from monospore culture sustained significantly higher yield (15.7 % BE) vis-à-vis tissue culture (14.6 % BE) and multispore spore cultures (13.0 % BE). The variations in the mushroom yield could be stabilized due to monospore culture. The cultures raised from tissue culture recorded highest radial growth in petriplates and maximum downward linear mycelial growth in spawn bottle(9.87 mm/day; 11.67 mm/day) as compared to monospore culture(9.38mm/day; 11.57 mm/day)) and multi-spore culture(8.65mm/day;11.33 mm/day). There was not much difference in the days taken for primordial initiation (9-10 days) and first harvest (14-15 days) irrespective of source of cultures. The average weight of sporophore was highest (12.8 g) in response to spawn raised from multispore cultures.
