摘要:

黑斑病是制约甘蓝生产的重要病害之一。从北京、重庆、湖北、四川、内蒙古5个甘蓝主产区采集黑斑病样本多份,经分离、纯化获得30株黑斑病病原菌,通过观察明确了黑斑病病原菌的菌落、孢子及孢子链形态特征。通过菌块接种法对上述病原菌进行致病性鉴定,确定从北京筛选出的BJA1菌株致病性最强。通过克隆BJA1菌株的ITS、TEF1、GAPDH基因,并进行系统发育分析,明确BJA1是芸薹生链格孢(Alternaria brassicicola)的典型菌株。利用该菌株建立了一套高效、稳定的甘蓝黑斑病抗性离体接种鉴定体系,确定适宜接种的菌液浓度为1 × 105 spores · mL-1,适宜接种的苗龄为四叶期。应用该体系对100份甘蓝种质进行黑斑病抗性评价,从中筛选出24份中抗材料,其中1份抗病材料病情指数25.93。

Abstract:

Black spot disease is one of the major constraints in cabbage production. Multiple black spot disease samples were collected from five major cabbage production regions Beijing,Chongqing,Hubei,Sichuan,and Inner Mongolia. After isolation and purification,30 strains of the pathogen were obtained. Morphological characteristics of the colonies,conidia,and conidial chains of the pathogen were observed and described. Pathogenicity tests conducted using mycelial plug inoculation identified the BJA1 strain from Beijing as the most virulent. Molecular identification through cloning and phylogenetic analysis of the ITSTEF1,and GAPDH genes confirmed that BJA1 is a typical strain of Alternaria brassicicola. Using this strain,an efficient and stable in vitro inoculation system for evaluating resistance to cabbage black spot disease was established. The optimal spore concentration for inoculation was determined to be 1 × 105 spores · mL-1,and the ideal plant growth stage for inoculation was the four-leaf stage. This system was applied to evaluate the resistance of 100 cabbage germplasms to black spot disease,leading to the identification of 24 moderately resistant accessions and one resistant accession with a disease index of 25.93.
