Abstract: A field experiment was conducted for two seasons at the Vaini Research Station, Kingdom of Tonga, to study the inheritance of vine thickness in sweet potato (Ipomoea batatas) and the relationship of different vine thicknesses to damage by the weevils, Cyles formicarius elegantulus (Summers) and Euscepes postfasciatus (Fairmaire). In this research, weevil numbers and the percentage of tubers and stems damaged by weevils were studies in thirty clones of sweet potato, which had either thin, medium or thick vines. Offspring of crosses from different parents were also studied to determine how vine thickness is inherited.
