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
