湖北省不同白肋烟品种(系)黑胫病抗性鉴定

Resistance Identification of Different Burley Tobacco Varieties(Lines) to Black Shank in Hubei Province

采用田间人工接种烟草黑胫病(Phytophthora parasitica)病菌0号和1号生理小种,对13份白肋烟资源连续两年进行烟草黑胫病田间抗性鉴定。结果表明,在参试13份白肋烟品种(系)中,对0号生理小种表现为抗的品种(系)有27018、27011、2619、2937、27123、2902、鄂烟1号等7份材料;对1号生理小种表现为抗的品种(系)有27018、27011、2619、2937、B0833、27015、27123、2902、鄂烟1号等9份材料。
