'Sanggang', a new cultivar of Agrocybe aegerita, was bred with mating between monokaryotic strains isolated from 'GMAG45109' and 'GMAG45107' in Mushroom Research Station, Gyonggi Province A.R.E.S. in 2009. The optimum temperature for the mycelial growth of 'Sanggang' was 26 to 28$^{\circ}C$ on PDA(potato dextrose agar) medium. The optimum temperature for the primordia formation and fruiting body development of 'Sanggang', was 18 to 20$^{\circ}C$. In the bottle cultivation of 'Sanggang', the period of spawn running was around 38 days at 22 to 23$^{\circ}C$ and the period from scratching of inoculum to harvest was 12 days. These characteristics of 'Sanggang' were not different from those of 'Mihwang' (control). 'Sanggang' had brown-colored pileus, whereas 'Mihwang' had yellowish brown-colored one. In bottle cultivation, 'Sanggang' hada little smaller but stronger stipe and pilus than 'Mihwang', and 'Sanggang', as well as 'Mihwang', had upright stipe. And 'Sanggang' was shown to have lower veil opening ratio than that of 'Mihwang' at harvest time.The yield of fruiting bodies of 'Sanggang' was 134 g/850ml bottle, which was similar to that of 'Mihwang'. Resistance of'Sanggang' against Trichoderma spp., as well as 'Mihwang', was weak. Freshness of 'Sanggang' was maintained for 13 days under storage temperature 4$^{\circ}C$, while that of 'Mihwang' was maintained for 10 days.

'Sanggang' was a new adlay cultivar which was developed from the three way crosses of $(Hukuhane\;{\times}\;Suwon-6)\;{\times}$ Suwon-6 at the Northern Agricultural Research Station, Gyunggido ARES. This cultivar had green sheaf, dark-green leaf, green culm, milky white silk and darkbrown seedcoat. Sanggang shortened 10 days of heading date and 12 days of ripening time compared with Yulmoo 1. In the yield's conponent of Sanggang, the number of grains was by 56 grains less but ripening rate and 1,000 grain weight were higher by 6.5% and 20.1 g compared with Yulmoo 1, respectively. This cultivar showed moderate resistance to leaf blight. The yield of Sanggang was about 313 kg/10a of unpolished grain at ordinary cultivation. This cutivar showed about 17% and 27% higher yield in Yonchon Gyeonggi province and Cheongju Chungbuk province compared with the check variety respectively. This cultivar was adaptable to mono cropping in central and northern region of Korea.
