Anthracnose disease is one of the major economic constraints to chilli production worldwide, especially in tropical and subtropical regions. Accurate taxonomic information is necessary for effective disease control management. In the Colletotrichum patho-system, different Colletotrichum species can be associated with anthracnose of the same host. Little information is known concerning the interactions of the species associated with the chilli anthracnose although several Colletotrichum species have been reported as causal agents of chilli anthracnose disease worldwide. The ambiguous taxonomic status of Colletotrichum species has resulted in inaccurate identification which may cause practical problems in plant breeding and disease management. Although the management and control of anthracnose disease are still being extensively researched, commercial cultivars of Capsicum annuum that are resistant to the pathogens that cause chilli anthracnose have not yet been developed. This paper reviews the causal agents of chilli anthracnose, the disease cycle, conventional methods in identification of the pathogen and molecular approaches that have been used for the identification of Colletotrichum species. Pathogenetic variation and population structure of the causal agents of chilli anthracnose along with the current taxonomic status of Colletotrichum species are discussed. Future developments leading to the disease management strategies are suggested.

以１８个豌豆栽培品种及野生种材料为ＤＮＡ样品来源，采用７个１０碱基随机引物进行ＰＣＲ扩增。基因组ＤＮＡ的多态性，利用ＲＡＰＤ标记鉴定其品种间及品种内的遗传变异性。７个引物共扩增出６６位点，其中多态性位点５６个，占８４．８％。每个ＰＣＲ扩增产物分别以０和１记录存在与否。扩增产物间成对比较产生非相似性矩阵（Ｊａｃｃａｒｄ相似系数表），此矩阵用于构建遗传相似性的树状系图谱（遗传树）。通过遗传树的构建将１０个Ｐ．ｓａｔｉｖｕｍ与８个Ｐ．ｆｕｌｖｕｍ群居为截然不同的两大组。
