Abstract

Sweet potato is one of the major food crops in Indonesia. More than 20 national varieties of sweet potato have been released by the Indonesian government since 1977. However, most of farmers in West Sumatra province have not used national varieties, but they consistently planted local varieties. Researches with the objectives of to overcome the characteristics, yield potentials, and organoleptic values of local cultivars of sweet potato in West Sumatra have been done in the period of 2016-2017. Researches were started with the exploration of sweet potato’s local cultivars of West Sumatra, continued with the characterization, testing of its yield potentials, and evaluating its organoleptic values. Exploration was done in Agam, Tanah Datar, and Solok regencies, the three central regions of sweet potato farming in West Sumatra. Characterization of the above sweet potato’s local cultivars was done at the Sukarami experimental farm of West Sumatra Assessment Institute for Agricultural Technology. An experiment for yield potential testing was conducted at the farmer’s field of Gunung Talang district, Solok regency. Organoleptic test was done involving farmers and extension workers as the panelists. Two national varieties of sweet potato, namely Antin-3 and Papua Solossa, were used as the control in the yield potential and organoleptic testings. Results showed that there were eight local cultivars of sweet potato planted mostly in West Sumatra, i.e. Daus, Pono, Wali and Bogor in Agam regency; Hitam Pucuk Panyalaian in Tanah Datar regency; and Wortel, Roti and Rajo Langik in Solok regency. These local cultivars have different characteristics in term of its growth performance, stems, leaves, and tubers. Two local cultivars, i.e. Rajo Langik and Wali, produced significantly higher yield (56.45 t/ha and 47.94 t/ha) than the national varieties Antin-3 (25.39 t/ha) and Papua Solossa (34.33 t/ha). All local cultivars tested produced significantly higher yield than Antin-3. Appearance, flavour, texture, color, and sweetness of boiled storage roots of all local cultivars of sweet potato in West Sumatra were not inferior to and even the local cultivar Daus better than the national varieties Antin-3 and Papua Solossa.
