摘 要：
由黄褐假单胞Pseudomonas fulva侵染引起的辣椒细菌性叶斑病是近期在新疆北疆加工辣椒生产区发现的一种新病害。为评估辣椒品种对细菌性叶斑病的抗性水平,采用苗期人工接种结合田间调查,鉴定了生产中13个主栽辣椒品种对细菌性叶斑病的抗性。结果表明,供试材料对细菌性叶斑病均无免疫性,但不同辣椒品种对辣椒叶斑病抗性差异较大,‘改良佳线1号’和‘丰力红冠’为抗病品种;‘佳线4号’、‘新丰6号’、‘秦椒王’、‘陕早红’、‘宝丰2号’为耐病品种;‘红安6号’、‘朝天椒’为感病品种,高感品种为‘金塔’、‘铁皮椒’、‘红龙13’和‘超级韩国甜椒’。研究结果为辣椒的抗病育种和病害防治提供了基础。

摘 要：
Pepper bacterial leaf spot caused by Pseudomonas fulva is a new disease on the cultivated processing pepper in North Xinjiang.In order to evaluate processing pepper resistance to bacterial leaf spot,seeds of 13 processing pepper materials were sown in flowerpot in the greenhouse,and suspension of inocula was sprayed or needled to the seedlings of 5-6true leaves,and then the resistance of pepper materials was evaluated based on disease index,as well as the field investigation results.The results indicated that there were no immune materials.‘Gailiangjiaxian 1'and‘Fenglihongguan'were resistant materials.‘Jiaxian 4', ‘Xinfeng 6', ‘Qinjiaowang',‘Shaanzaohong'and‘Baofeng 2'were tolerant to bacterial leaf spot;‘Hongan6',‘Chaotianjiao'were susceptible varieties,and ‘Jinta',‘Honglong 13',‘Tiepijiao'and ‘Chaojihanguotianjiao'were high susceptible ones.The above results provide the theory basis for pepper disease resistance breeding and disease control.
