| Abstract: | ‘Gengyu 2’is a new konjac cultivar bred from Amorphophallus muelleri varieties populations by systematic breeding method.‘Gengyu 2’achieves on higher yield and resistant to diseases. The average yield is up to 45 t · hm-2，50% higher than that of local A. konjac seed. The morbidity of bacterial soft rot decreased 60% than local A. konjac seed. The growth period is 240 d. The corm has 52.8% dry matter，which has 43.69% konjac glucomannan（KGM）and 14 600 mPa · s viscosity. It is suitable to be cultivated in altitude 600–1 600 m of Southeast of China mountain. |
