Abstract
'Cham', a new cultivar of Agrocybe aegerita, was bred by crossing between monokaryotic strains isolated from GMAG45021 and 'Beodeulsongi1ho' in Mushroom Research Station, Gyonggi Province A.R.E.S. in 2007. The optimum temperature for the mycelial growth of 'Cham' was 26 to $28^{\circ}C$ on PDA medium, whereas that of 'Beodeulsongi1ho'(control) was 24 to $26^{\circ}C$. The optimum temperature for the primordial formation and fruiting body development of 'Cham', as well as 'Beodeulsongi1ho', was 18 to $20^{\circ}C$. In the bottle cultivation, the spawn run period of 'Cham' at 22 to $23^{\circ}C$ was around 38 days and the period from scratching of inoculum to harvest was 12 days. These characteristics of 'Cham' were not different from those of 'Beodeulsongi1ho'. However, 'Cham' had more dark brown-colored, and thicker and stronger pileus, and longer and thicker stipe compared to that of 'Beodeulsongilho'. Freshness of 'Cham' was maintained for 10 days at the storage temperature of $4^{\circ}C$, while that of 'Beodeulsongi1ho' was maintained for 8 days. Moreover, the yield of fruiting bodies of 'Cham' was $141g/850m{\ell}$ bottle, which was similar to that of 'Beodeulsongi1ho'. Both 'Cham' and 'Beodeulsongilho' have lower resistivity against Trichoderma virens and Trichoderma harzianum.
