Effect of base material, different strains on pattern of flushes and yield of Agaricusbisporus (Lange) sing

Wheat straw based compost gave significantly higher yield and number of fruit bodies (F-I: 293.10 and F-ll: 230.50 g/2kg of compost) as compared to sugarcane bagassc (F-III: 130.80 g/2kg of compost). Strain MS-39 gavc significant higher mushroom yield (335.00 g/2 kg of compost) in colllparison to strains Pant-31 (326.25g), IIU-3 (319.50g), NCS-143 (265.25g) anu Pant-52 (260.50g). In addition to this MS-39 and IIU-3 produced excellent white fruit bodies. The maximum number of fruit bodies were produced in strain Pant-31 (29.75) auu maximum individual fruit body weight was found in strain IIU-3 (12.17g). Strain Pant-31 aud IIU-3 were found to be the best in terms of keeping quality, because those retained excelleut whiteness with no veil opening up to 120, 72 and 43 hrs of storage period at 5, 12 and 18 °C temperature, respectively.
