摘要: 辣椒是茄科重要经济作物,具有合轴分枝结构。始花节位是辣椒的重要熟性性状,与辣椒采收期和早期产量显著相关。开花时间在作物驯化及适应新气候环境过程中起重要作用,开花意味着植物从营养生长阶段转换到生殖生长阶段,始花节位常被用来衡量辣椒开花的时间。文章就辣椒始花节位的遗传定位、相关基因及其相互关系,以及这些基因功能的保守性和多样性等进行了综述,并就今后的发展方向和重点进行了展望,提出建设性意见。

Abstract: Pepper (Capsicum spp.) is an important economic crop in Solanaceae with sympodial shoot architecture. First-flower-node (FFN), also described as the number of leaves on the primary axis (Nle), number of leaves on primary stem until first flower or number of nodes, is a main maturity trait in pepper, which is closely related to precocity and early yield. Flowering time has an important role in crop domestication and adaptation to novel environments. The timing of the initial transition to flowering can be best measured by FFN. This paper reviewed the research of FFN in pepper, including genetic mapping, knowledge of associated genes identified by EMS induced mutants, functional conservation and diversity of these genes, as well as the interrelationship of them, and prospected the future directions and suggestions.

Key words: pepper, first-flower-node, flowering
