摘要
为了解广东省推广种植的菜心Brassica parachinensis品种对菜心炭疽病的抗性水平,对广东省13个具代表性菜心品种进行菜心炭疽病的抗性鉴定。结果显示,供试13个菜心品种对菜心炭疽病的平均病情指数为44.61~74.19,其中80天油青菜心的平均病情指数最低,粗苔49油青甜菜心的平均病情指数最高。80天油青菜心等6个品种对菜心炭疽病表现为中抗水平,粗苔49油青甜菜心等7个品种对菜心炭疽病表现为感病水平。目前在广东省生产种植的菜心以菜心炭疽病感病和中抗品种为主,缺乏菜心炭疽病抗性或高抗品种。
In order to clarify resistant levels of Chinese flowering cabbage cultivars planted in Guangdong province to anthracnose disease caused by Colletotrichum higginsianum,thirteen typical cultivars were tested in this study.The results showed that the average disease index range of the13cultivars to anthracnose disease was44.61-74.19,the average disease index of cultivar80-tian-you-qing was lowest,and the average disease index of cultivar Cu-tai-49-you-qing was highest.Seven cultivars including Cu-tai-49-you-qing were susceptible to anthracnose disease.Other six cultivars including80-tian-you-qing were moderate resistant to anthracnose disease.These results suggested that there were no resistant or high resistant cultivars of Chinese flowering cabbage to anthracnose disease planted in Guangdong province at present in commercial production.
