ABSTRACT=<p>Flowering time influences reproductive success in plants and has a significant impact on yield in grain crops. Flowering time is regulated by a variety of environmental factors, with daylength often playing an important role. Crops can be categorized into different types according to their photoperiod requirements for flowering. For instance, long-day crops include wheat (<italic>Triticum aestivum</italic>), barley (<italic>Hordeum vulgare</italic>), and pea (<italic>Pisum sativum</italic>), while short-day crops include rice (<italic>Oryza sativa</italic>), soybean (<italic>Glycine max</italic>), and maize (<italic>Zea mays</italic>). Understanding the molecular regulation of flowering and genotypic variation therein is important for molecular breeding and crop improvement. This paper reviews the regulation of flowering in different crop species with a particular focus on how photoperiod-related genes facilitate adaptation to local environments.</p>
