Early flowering refers to the phenomenon in which the first flower appears in fewer days than normal, regardless of the sex of the flower. It is a significant feature impacting the early maturity and economic yield of cucumbers. The early flowering trait of cucumber is influenced by several factors. Considering its heritability, technologies such as whole-genome sequencing, genetic modification, bioinformatics analysis, quantitative trait locus (QTL) mapping, molecular marker-assisted selection, and gene editing are widely used to explore the regulatory genes and molecular mechanisms of the early flowering trait in cucumbers. This review aimed to summarize the factors, QTL mapping, molecular regulation mechanisms, and omics analysis related to early flowering traits in cucumbers. This review contributes theoretical insights to support both cucumber breeding for early flowering and fundamental research on early flowering traits.
早花是指第一朵花出现的天数比正常情况少的现象，无论花的性别如何。它是影响黄瓜早熟和经济产量的一个重要特征。黄瓜的早花性状受多种因素影响。考虑到其遗传特性，全基因组测序、基因编辑、生物信息学分析、数量性状位点（QTL）定位、分子标记辅助选择和基因编辑等技术被广泛用于探索黄瓜早花性状的调控基因和分子机制。本综述旨在总结与黄瓜早花性状相关的因素、QTL定位、分子调控机制和组学分析。本综述为支持黄瓜早花育种和早花性状的基础研究提供了理论见解。
