Abstract: Melinis repens （Willd.） Zizka is a highly stress-resistant grass species of the Poaceae family in tropical regions, which is tolerant to high temperatures, drought, and barrenness.It possesses ornamental, forage, ecological, and medicinal values, demonstrating significant application potential in tropical areas. The widespread use of Melinis repens （Willd.） Zizka for ecological slope protection and landscaping requires a substantial supply of seeds. However, seed production of Melinis repens （Willd.） Zizka faces challenges such as low seed-setting rates, inconsistent maturity periods, strong seed dormancy, and low germination rates.Therefore,based on analysis of the existing literature and combined with the research results of other forage grasses in the Poaceae family, this paper comprehensively reviewed the biological characteristics, geographical distribution, reproductive traits, seed biological properties, seed propagation techniques, and tissue culture systems of Melinis repens （Willd.） Zizka. The study summarized technical difficulties and key issues in seed propagation of Melinis repens （Willd.） Zizka, and proposed future research directions, to provide important guidance for improving seed production. Additionally, it also offered reference for the conservation and promotion of Melinis repens （Willd.） Zizka germplasm resources.

Key words: Melinis repens （Willd.） Zizka, seed viability, seed yield, germination characteristics, tissue culture techniques
