Sweetpotato evaluation in Peru

Hidalgo, O.A. | Molina, J.P. | Fonseca, C.
Peru's National Sweetpotato Program is testing genetic material mainly generated by the breeding program and germplasm collection at CIP. Work is carried out in several parts of Peru, especially on the coast, with participation of nine INIA experiment stations, six NGOs, five universities, CIP, and private-sector companies. Evaluation of genetic material is based on a four-phase plan in which observation, advanced, on-farm, and validation trials are conducted. This reduces the number of clones selected before a new variety is released. A new variety, 'Canetano-INIA', was recently released, and is now being multiplied and distributed to Peruvian farmers. A National Sweetpotato Program publication, edited by CIP, explains the steps for appropriated testing with active farmer participation. The technical and participatory evaluations done by scientists and farmers, respectively, are one way to evaluate clones tested in each step of the process. Materials are tested mainly for selecting for direct consumption as well as for processing and forage. Several hundred clones are tested every year in Canete, the National Sweetpotato Program's headquarters for testing and distributing sweetpotato genetic material. In addition, four other sites (Chiclayo, Huanuco, Cusco and Tacna) are being used to redistribute genetic material to another 14 secondary site in Peru. The selection process, showing number of clones tested/selected, will be presented, especially for Canete and the other four locations, as an example of progress made. The national program emphasizes the selection of genetic material for industrial purposes, mainly for starch production. Five advanced clones are now at the validation stage, with high yield dry matter, and starch content. Specific data on clones selected are also presented.
