SUMMARY:

The aim of the study was to characterize accessions of yam Dioscorea spp. as to the proximate composition (moisture, ash, lipids, carbohydrates and proteins), the total energy value (TEV) and the content of mineral elements. The accesses were obtained from collection expeditions in the main producing municipalities in the States of Alagoas and Sergipe. Thus, two accessions of Dioscorea trifida were captured; six from D. cayenensis, one from D. bulbifera and one. D. alata. All analyzes were carried out from 11/23/2020 to 12/10/2020. The dataset was submitted to the Kolmogorov-Smirnov normality test and, as it presented normality, descriptive statistics such as mean and standard deviation and multivariate analyzes were analyzed as a determination of genetic divergence from dissimilarity measures such as the mean Euclidean distance and cluster analysis as the Tocher method. The results sought that the accessions of different species of Dioscorea have potential for use in human food and that they can be better used by local populations. As, for example, we can mention the accessions 2, 9 and 10 which have protein content above the average in relation to the other genetic materials. As well as some accessions that stood out, such as Access 10 that presented high levels of zinc, magnesium and potassium, while Access 5 stood out in relation to manganese content. On the other hand, the study showed the little variability that exists in the materials, evidencing the need to leave these materials and rescue those that the producers of the different traditional categories established to plant.
