    煙草抗病毒病種質(zhì)資源的鑒定與評(píng)價(jià)

    Resistance Identification and Evaluation of Tobacco Germplasms to Tobacco Virus Diseases

    • 摘要: 2005－2006年采用溫室苗期接種鑒定的方法對(duì)202份煙草種質(zhì)進(jìn)行了TMV,、CMV以及PVY三種病毒病的抗性鑒定。結(jié)果表明：在供試種質(zhì)中,，對(duì)TMV表現(xiàn)免疫（21份）,、抗病（1份）和中抗（30份）的材料共52份,，表現(xiàn)中感（130份）和感?。?0份）的材料共150份；對(duì)CMV表現(xiàn)抗性（4份）和中抗（20份）的材料共24份,，表現(xiàn)中感（79份）和感?。?9份）的種質(zhì)共178份；對(duì)PVY表現(xiàn)免疫（1份）,、抗?。?份）和中抗（33份）的材料共36份，表現(xiàn)中感（96份）和感?。?0份）的材料共166份,。所篩選的優(yōu)質(zhì)、抗病烤煙引進(jìn)品種白色種,、曬煙大るま以及香料煙KoKulu izmir可直接應(yīng)用于煙草生產(chǎn),，另外對(duì)TMV表現(xiàn)免疫的材料白肋煙8301、黃筋蔸,、抗3種病毒病的種質(zhì)黃花煙陽(yáng)高小蘭花以及兼抗兩種病毒病的種質(zhì)可為煙草抗病毒病育種的親本選擇提供抗源,。

       

      Abstract: 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 carried 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.
