The seaweed Kappaphycus alvarezii , commonly known as cottonii is the most important seaweed species cultured in Indonesia. This seaweed is widely cultivated as a main income source for communities in coastal areas of Southeast (SE) Sulawesi. In general, grafting has been rarely used in the seaweed K. alvarezii . An attempt was made to graft the K. alvarezii in the shallow waters at Bungin Permai, South Konawe, SE‐Sulawesi of Indonesia. Tissue‐cultured and local strains were selected for intra‐generic grafting. The methods of graft combinations were side‐ and straight‐slipped positions. Each combination contained 30 grafting plants. Between intra‐generic grafted plants, straight position was found to attach after 9 days. For side‐slipped position, it took 21 days to attach. In conclusion, due to easy and fast vegetative potential, high intra‐generic grafting success using straight‐slipped position method for grafting is achievable.
