Comparision of Growth Parameters and Yield Potential of the Three Strains of Agaricus bisporus

The studies of growth behaviour and yield potential of different strains (S-79, A-15 and Delta) of A. bisporus were tested. The spawn run periods were same 16 days in S-79 and Delta while A-15 was completed in 17 days. Initiation of pinhead early appeared (25 days) S-79 while A-15 and Delta were appeared in 26 days. The harvesting of 1^st, 2^nd, 3^rd and 4^th flushes were early completed (31, 41, 53 and 64 days) from strain S-79 followed by Delta and A-15. Comparative yield of various strains of A. bisporus showed that the S-79 was better performance and followed by A-15 and Delta respectively. However, there was some variation in the weight; pileus diameter and stipe (stalk) length of fruit bodies of various strains under evaluation. Average no. of fruit bodies was most responsible in the yield potential. The no. of fruit bodies in strain S-79 was maximumfollowed by A-15 and Delta respectively. The strain S-79 was giving the better performance of yield potential of all three strains of A. bisporus.
