部分烟草种质资源的PVY 抗性鉴定

Resistance Identification to PVY of Some Tobacco Germplasm Resources

摘要: 通过对69 份烟草种质资源的马铃薯Y 病毒（PVY）病圃人工诱发接种鉴定，初步筛查出C151、Hawana10、坝林晒烟和Criollo salteno 11 等11 份表现为高抗PVY 的烟草种质资源，其中烤烟3 份，晒烟3 份，黄花烟3 份，雪茄烟2 份。C151 属于烤烟类型，花色白，田间可采叶数22～24 片，叶形长椭圆，叶色深绿，可作为抗PVY 育种亲本。

Abstract: Artificial inoculation in tobacco field was conducted to identify the resistance of 69 tobacco germplasm to PVY. 11 germplasm exhibit high resistance to PVY, they are C151, Havana 10, Balin-Shaiyan and Criollo salteno 11, among which there are 3 flue-cured tobacco varieties, 3 sun-cured tobacco varieties, 3 Turkish tobacco varieties and 2 cigar tobacco varieties, respectively. C151 is a flue-cured tobacco variety with white flowers, and 22 to 24 long-ellipse leaves available in field, the leaf color is green, so C151 can be a useful breeding parent.
