Title: Development and yield evaluation of non-browning hybrids in button mushroom (Agaricus bisporus)

Abstract:
Browning in white button mushroom after harvest is a major limiting factor affecting the quality and marketability of mushrooms. In the present study, 361 hybrids were developed using non-fertile isolates from 11 strains and evaluated for their bruise resistance by applying mechanical injury using a fork. In majority of the cases, the browning started immediately after the injury whereas a few remained unchanged even after two hours. After preliminary yield evaluation, five of these were selected and each hybrid was evaluated for yield on 1000 kg compost in a commercial unit. Finally, two of them (NBS-1 and NBS-5) were selected on the basis of better quality and higher yield. Final trial of the two strains was done on 4500 bags of 10 kg compost each in three commercial units. The yield of the two strains ranged between 21-25 kg per 100 kg of compost in a total harvesting period of 15 days. These two strains out yielded the strains used by those commercial units.
