摘　　要：为了鉴定引进烤烟品种‘云烟116’在宜宾烟区的田间抗病性,2020年在四川省兴文县3个不同生态区选择常年发病、重发病田(地)块,与对照品种‘云烟87’进行对比研究。结果表明,与对照品种‘云烟87’相比较,烤烟品种‘云烟116’的根黑腐病发病率低2.00~3.00个百分点、病情指数低34.33%~100.00%,黑胫病发病率低0.00~2.00个百分点、病情指数低12.36%~100.00%,病毒病发病率低2.00~6.00个百分点、病情指数低16.08%~100.00%,赤星病发病率低1.00~5.00个百分点、病情指数低4.95%~58.73%,青枯病发病率低1.00~2.00个百分点、病情指数低15.28%~50.00%;根据差异显著性分析,烤烟品种‘云烟116’对病毒病、根黑腐病、黑胫病、赤星病的田间抗病性优于对照品种‘云烟87’,对青枯病的田间抗病性与对照品种‘云烟87’相当。综合而言,烤烟品种‘云烟116’的田间综合抗病性优于对照品种‘云烟87’,可在宜宾烟区推广应用。In order to identify the field disease resistance of'Yunyan 116'in Yibin tobacco area,the fields(plots)with perennial and severe disease incidence were selected from 3 different ecological zones of Xingwen County,Sichuan Province in 2020,and a comparative study with control variety'Yunyan 87'were conducted.The results showed that compared with'Yunyan87',the disease incidence and disease index of black root rot were decreased by 2.00-3.00 percentage points and 34.33%-100.00%,respectively;the disease incidence and disease index of black shank were decreased by 0.00-2.00 percentage points and 12.36%-100.00%,respectively;the disease incidence and disease index of virus disease were decreased by 2.00-6.00 percentage points and 16.08%-100.00%,respectively;the disease incidence and disease index of Alternaria alternata were decreased by 1.00-5.00 percentage points and 4.95%-58.73%,respectively;the disease incidence and disease index of bacterial wilt were decreased by 1.00-2.00 percentage points and 15.28%-50.00%,respectively.According to the difference significance analysis,the field resistance of'Yunyan 116'to virus disease,black root rot,black shank,and Alternaria alternata was better than'Yunyan 87',and the field resistance to bacterial wilt was equal to'Yunyan 87'.In summary,the field comprehensive disease resistance of'Yunyan 116'is better than'Yunyan 87',which could be applied in Yibin tobacco area.
