摘要：

119份烟草种质资源后期的烟杈TMV发病情况调查结果与TMV抗性鉴定结果比较看出，烟杈TMV发病情况与抗病性鉴定结果有一定的规律性。从某种意义上来说，烟杈TMV的病株率和病指可作为某种质对TMV抗性水平的参考值，在没有条件开展TMV人工接种鉴定的情况下，烟杈TMV发病情况基本能正确反映种质对TMV的抗性水平。该法可用于抗TMV烟草种质资源的初步筛选。

Abstract:

Analysis and compare with TMV incidence of the branches of 119 tobacco germplasm resources and the results of disease resistance identification of these germplasm resources. The results showed that, there are a certain regularity of the TMV resistance identification results and TMV incidence of the branches of tobacco germplasm resources. In a sense, TMV incidence of branches of tobacco germplasm resources can be used as the reference value of TMV resistance level. Especially for to screening of the disease resisted tobacco germplasm resources when absence of the conditions to artificial inoculation to TMV resistance identification. The results can correctly reflect the germplasm resources of TMV resistance level, this method can be applies to the initial screening of TMV resistance tobacco resources especially.
