| 摘 要： | 采用魔芋Amorphophallus spp.块茎点种、注射、灌根接种及田间调查等方法，对国内普遍栽种的珠芽红魔芋A. bulbifer、珠芽金魔芋A. muelleri、花魔芋A. konjac和白魔芋A. albus等12个种质材料进行抗软腐病鉴定、比较和评价，以分析珠芽魔芋对抗细菌性软腐病的抗病水平。结果表明，供试材料对软腐病抗性差异较大，珠芽金魔芋种质对细菌性软腐病均有免疫性(I)，德宏及临沧珠芽红魔芋种质为高抗病品种(HR)；缅甸珠芽红魔芋为抗病品种(R)；富源花魔芋、楚雄花魔芋、日本农林2号、鄂魔芋1号、秦魔1号、昭通白魔芋、丽江白魔芋均属易感品种(S)，与田间抗性调查情况基本相符。

| Abstract: | Soft rot disease of Erwinia carotovora subsp. carotovora in konjac is the most important diseases. The resistence to soft rot disease of Erwinia carotovora subsp. carotovora among 12 konjac (Amorphophallus spp.) cultivars were evaluated by different inoculation methods and fields disease survey. The results showed that A. konjac and A. albus were susceptible cultivars (S), A. bulbifer from Dehong city and Lincang city were highly resistant materials (HR), A. bulbifer from Myanmar was resistant materials (R), while A. muelleri was immune resistant (I). The results confirmed to fields disease survey. |
