In the present investigation, 68 samples of native potatoes collected and cultivated in the Matipacana peasant community of the Yauli District, of the Huancavelica Province and Region, were characterized morphologically. 27 morphological descriptors were used for the characterization of leaves, stems, flowers and tubers according to the evaluation criteria for each qualitative descriptor described in the “Guide for basic morphological characterizations in native potato collections“. The results of the univariate analyses, the similarity test and the principal components of the multivariate analysis are presented. In the univariate analysis, the descriptive statistics of the morphological characteristics were recorded. The highest frequency of leaves of the analyzed samples presented between 4 to 7 pairs of primary leaflets, only the “qeqorani“ sample showed 7 pairs; In addition, only one sample with 3 pairs and one with 2 pairs of secondary and tertiary leaflets, respectively, was found. Regarding the primary color of the flowers, those of violet and purple color were more frequently registered, which represented 38.2 and 36.8 percent respectively; none of the samples presented pigmentation in the anthers. The tubers presented all the general shapes with the exception of the elliptical shape, the elongated shape being the most frequent. The samples with yellow skin were the most numerous (27.0 percent), no pink or brown skins were recorded; 50 percent did not show secondary color and superficial eyes were the most numerous (39.7 percent). In the results of the multivariate analysis, the dendrogram prepared at a distance level of 0.05 allowed the identification of 64 samples that were different from each other and two pairs of samples with the highest similarity, although between them they showed four different descriptors. The Principal Components Analysis (PCA) showed that the predominant color of the skin and the secondary color of the pulp of the tuber, the predominant color of the flower, the variant forms of the tuber and the pigmentation of the pistil are the major ones responsible for the variability. total morphology of the collection.
