Abstract Bacterial wilt is a major devastating soil-borne disease, caused by Ralstonia solanacearum, that impedes eggplant cultivation worldwide. The progress in developing eggplant varieties or hybrids possessing bacterial wilt resistance is encouraging. However, as the pathogen is evolving quickly, understanding the pathogen dynamics and reliable screening methods is important. The knowledge on genetic diversity of eggplants and their wild relatives, gene action and available molecular markers is essential for breeders. Advances in next-generation sequencing technologies and available genomic sources are permitting precise mapping. Development of single-nucleotide polymorphism-based markers and available markers associated with resistance will accelerate breeding programmes. Grafting technology, in which resistant sources are used as rootstocks, is also gaining considerable importance recently. This technique helps in saving time by avoiding the effort required in changing genetic backgrounds through breeding. The present review emphasises the available knowledge regarding the pathogen, genetic resources, root stock breeding and progress made in conventional and marker-assisted breeding for bacterial wilt resistance in eggplant globally.

茄子（Solanum melongena L.）青枯病抗性育种：进展与展望

摘要 青枯病是一种主要的破坏性土传病害，由青枯病菌引起，在全球范围内阻碍了茄子的种植。开发具有青枯病抗性的茄子品种或杂交种的进展令人鼓舞。然而，由于病原体进化迅速，了解病原体动态和可靠的筛选方法很重要。茄子及其野生近缘种的遗传多样性、基因作用和可用的分子标记的知识对于育种者来说是必不可少的。新一代测序技术和可用基因组来源的进步使得精确定位成为可能。开发基于单核苷酸多态性的标记和与抗性相关的可用标记将加速育种计划。嫁接技术，其中抗性来源用作砧木，最近也变得越来越重要。该技术避免了通过育种改变遗传背景所需的努力，从而有助于节省时间。本综述强调了有关病原体、遗传资源、砧木育种以及全球茄子青枯病抗性常规和标记辅助育种方面的现有知识。
