In the Amazon, a great variability of peanuts is preserved, which in the region is very widespread, to be used in food; They have knowledge of the origin and cultivation, they differentiate it with their own names of the area. There are invariable genetic characters that differentiate local varieties, associated with agronomic characters of descriptive value and perception for the community; the collections, characterizations and evaluations of peanuts from the Amazon will provide more elements in determining variability. The richness index for local names of peanuts, in collection sites, is high in the Ucayali River Basin, where it is known by 4 to 5 names. In relation to climatic factors, the minimum annual temperature is in the range of 16 ° C and 22 ° C, and maximum of 28 ° C and 33 ° C. The Cluster analysis of 65 entries of peanuts, allowed to find 10 different groups that end up on a single root, at a similarity level of 0.15. The Shannon diversity index turned out to be higher for the growth habit character. The multiple regression of the characters indicates good predictability, and explains that 27% of the total variation is due to the effect of the environment. The first analysis of genetic erosion, carried out, indicates that the Third Sector (Padre Abad district) of the Aguaytia River Basin, has a greater threat of erosion risks or loss of valuable genes. The observed model is explained by distributional limits of populations, the northern latitudes and western longitudes are in distribution limits, and have restricted gene flow with the rest of the populations. The low levels of significance found in the regression analyzes indicate that the characters have adapted to the Ucayali Basin, from which they have been distributed to other basins.
