常用的对大白菜抗病毒病的鉴定方法有室内人工接种鉴定,田间人工接种鉴定和田间自然诱发鉴定.这些方法需要较长时间,同时往往由于环境条件控制不严,人工接种方法不同,甚至有自然条件不诱发病害发生等,加之鉴定的主观性,对同一试材的鉴定结果往往差异较大.为了寻找简捷、快速、客观、定量的鉴定方法,揭露抗病性与相关生理生化性状遗传变异规律,而进行了抗病性与生理生化性状相关性的研究,以便为育种方法的改进,提高育种效率提供理论根据.
Commonly used in the identification of Chinese cabbage antiviral disease have artificial inoculation identification, field artificial inoculation identification and field induced identification of these methods take a long time, often due to lax environmental control, artificial inoculation methods are different, and even have Natural conditions do not induce the occurrence of diseases, combined with the identification of the subjectivity of the same test material identification results tend to be quite different.In order to find a simple, rapid, objective and quantitative identification methods, revealing disease resistance and related physiological and biochemical traits genetic variation The correlation between disease resistance and physiological and biochemical traits was studied in order to provide a theoretical basis for the improvement of breeding methods and breeding efficiency.
