The training/support mission was carried out to train Cirad-Guadeloupe on conducting a new SOP for the measurement of extensibility of pounded yam by the Kieffer dough extensibility (KDGE) and lubricated squeezing flow procedures (LSF) and using already existent SOP for boiled yam characterisation by penetrometer. Moreover, a part of CIRAD-Guadeloupe collection was characterised (D. Alata genotypes) in order to evaluated potential use of these genotypes for pounded yam production. The partners were trained on how to prepare the samples for evaluation, carry out the textural procedures, analysis of the data, dry matter, NIRS and colour determination and precautionary measures needed to ensure accurate conduct of the procedures.
