TAILIEUCHUNG - Evaluation of high yielding strains of oyster mushroom (Pleurotus spp.)

Five strains of oyster mushroom were tested for various parameters such as spawn run days, pin head initiation days, days taken for first harvest, fruit body/bag, and average weight of fruit body, yield and biological efficiency. Results indicate that highest biological efficiency was recorded in strain R-13-13-05 ( %) followed by strain R-13- 13-07 ( %), R-13-13-03 ( %) and R-51 ( %), respectively, and Lowest BR was observed in strain R-13-13-04 ( %) among all the tested strains. Days required for spawn was minimum in strain R-13-13-05 (only 17 days) followed by R-13-13-04 (only days), strains R-13-13-07, R-51 (only days) and strain R-13-13-03 (only days), respectively. Maximum required days, for spawn run, were recorded in strain R-13- 13-3 (total days). Pin head initiation was first reported in strain R-13-13-5 (within days) followed by strain R-51 (within days), strains R-13-13-04 (within days) and strain R-13-13-03 (within days), respectively. Maximum days, required for pin head initiation, were in strain R-13-13-07 (within days). First harvesting was done in strain R-13-13-05 (after days of spawning) followed by strains R-13-13-03, R-13-13-07, R-51 and R-13-13-04 (after , , , days of spawning, respectively). Among all the strains, tested in the experiment, strain R-13-13-07 recorded highest fruit body weight (per fruit body g) followed by R-13-13-04 ( g), strains R-13-13-05, ( ) and R-51 ( g ), respectively. | Evaluation of high yielding strains of oyster mushroom (Pleurotus spp.)
