Abstract

Sources of resistance are an important control measure for witches' broom disease in cacao. Their identification through quantitative trait loci (QTLs) and genetic diversity analysis would assist breeding programs to develop new cultivars with improved resistance traits. We conducted a systematic review that compiles the main advances in the search for resistance to witches' broom disease. The systematic review on Scopus, Springer Link, PubMed, SciELO, and Web of Science databases followed the Preferred Reporting Items for Systematic Reviews and Meta‐Analysis (PRISMA) guidelines using the State of the Art through Systematic Review (StArt) software. We identified genotypes exhibiting the most significant resistance in phenotypic analysis, along with combinations of crosses that are promising for future studies and cultivar development. Data on genetic diversity indicate a wide possibility of benefits from heterozygosis. Genetic mapping and association studies revealed eight QTLs associated with resistance and several candidate genes with known and unknown biological functions. More comprehensive research of the various sources of resistance to witches' broom disease is crucial for the advance of cacao breeding programs.

可可（Theobroma cacao L.）对女巫扫帚病的抗性来源：最新进展与展望

抗性来源是可可中女巫扫帚病的重要控制措施。通过定量性状位点（QTLs）和遗传多样性分析确定抗性来源将有助于育种计划开发出具有更好抗性特征的新栽培品种。我们进行了一项系统综述，汇编了在寻找可可对巫婆帚病的抗性方面取得的主要进展。在 Scopus、Springer Link、PubMed、SciELO 和 Web of Science 数据库上进行的系统综述遵循了系统综述和元分析首选报告项目（PRISMA）指南，并使用了系统综述艺术现状（Start of the Art through Systematic Review，StArt）软件。我们确定了在表型分析中表现出最显著抗性的基因型，以及有望用于未来研究和栽培品种开发的杂交组合。有关遗传多样性的数据表明，杂合子可能带来广泛的益处。基因图谱绘制和关联研究发现了八个与抗性相关的 QTL 以及几个具有已知和未知生物功能的候选基因。对巫婆帚病的各种抗性来源进行更全面的研究，对于推进可可育种计划至关重要。
