摘要
2005-2006年采用温室苗期接种鉴定的方法对202份烟草种质进行了TMV、CMV以及PVY三种病毒病的抗性鉴定。结果表明:在供试种质中,对TMV表现免疫(21份)、抗病(1份)和中抗(30份)的材料共52份,表现中感(130份)和感病(20份)的材料共150份;对CMV表现抗性(4份)和中抗(20份)的材料共24份,表现中感(79份)和感病(99份)的种质共178份;对PVY表现免疫(1份)、抗病(2份)和中抗(33份)的材料共36份,表现中感(96份)和感病(70份)的材料共166份。所筛选的优质、抗病烤烟引进品种白色种、晒烟大るま以及香料烟KoKulu izmir可直接应用于烟草生产,另外对TMV表现免疫的材料白肋烟8301、黄筋蔸、抗3种病毒病的种质黄花烟阳高小兰花以及兼抗两种病毒病的种质可为烟草抗病毒病育种的亲本选择提供抗源。
The identification and evaluation of 202 germplasms resistant to three tobacco viruses： tobacco mosaic virus （TMV）, cucumber mosaic virus （CMV） and potato virus Y（PVY）, were carded out in greenhouse from 2005 to 2006. The results are as follows. To TMV, 21 germplasms were immune, one was resistant, 30 were medium resistant, 130 were medium sensitive and 20 were sensitive. To CMV, 4 were resistant, 20 were medium resistant, 79 were medium sensitive and 99 were sensitive. To PVY, one was immune, 2 were resistant, 33 were medium resistant, 96 were medium sensitive and 70 were sensitive. For superior quality and resistance, Baisezhong （flue-cured tobacco）, Big るま （sun-cured tobacco） and KoKulu izmir （oriental tobacco） can be used directly. The other germplasms including 8301 and Huangjindou （both are burley）, immune to TMV, and Yanggaoxiaolanhua （N. rustica L.）, resistant to three virus diseases, may be utilized as parent materials in breeding for virus resistance.
