La Uvina es una de las ocho variedades de uva permitidas para la elaboración del pisco en el Perú y forma parte del patrimonio cultural del país. Sin embargo, no se ha estudiado ampliamente el efecto de los portainjertos sobre sus propiedades. Se evaluó la influencia de diferentes portainjertos en las características morfo-productivas de Uvina del Banco de Germoplasma del INIA, considerando catorce caracteres cualitativos. Se realizaron análisis descriptivos, ANOVA con comparación de medias mediante la prueba de Tukey (p≤0,05) y, para pruebas no paramétricas, el test de Kruskal-Wallis con post hoc de Holm (p≤0,05), además de análisis de correlación de Pearson y componentes principales. Los resultados evidenciaron que los portainjertos Salt Creek y 5BB sobresalieron por presentar el mayor número y masa de racimos por planta, así como mayor largo de entrenudos y masa de sarmientos. Paulsen mostró un desempeño intermedio, mientras que MGT registró los valores más bajos en la mayoría de las variables analizadas, con excepción del contenido de sólidos solubles totales, parámetro en el que superó a los demás. Se concluye que los portainjertos influyeron significativamente en las características morfo-productivas de la Uvina.

Today's wine and Pisco grape production in Peru is largely dominated by a reduced number of grapevine (Vitis vinifera L.) varieties. However, Peru is home to a high number of lesser-known local varieties that are still present in traditional vineyards and/or preserved in national or regional grapevine collections, of interest to diversify the local industry. Here, we analyzed 121 grapevine accessions preserved in the ampelographic collection of the Instituto Nacional de Innovación Agraria (INIA-EEA) at Chincha (Ica, Peru), using a combined SNP and SSR genetic profiling strategy for their molecular characterization and identification. This approach led to the differentiation of 45 different grapevine genetic profiles, 40 of them corresponding to already catalogued table and wine grape varieties of diverse geographic origin. Interestingly, we found five grapevines with genetic profiles not registered before. Some of them were found to be descendants of Listán Prieto and/or Muscat of Alexandria, increasing the known role of these two varieties as founders of the Criolla varieties, the autochthonous South American grapevine germplasm. A predominance of the varieties Listán Prieto and Quebranta was also observed, as they were found to be preserved multiple times in the INIA-EEA Grapevine Collection under different local synonyms. Strikingly, the phenotypic description of different accessions matching the genotypes of these two relevant varieties showed a high degree of phenotypic diversity, including the identification of novel berry-color and Muscat-flavored somatic variants that might have a direct impact toward local grape industry diversification. These findings underline the importance of the local genetic resources preserved at the INIA-EEA Grapevine Collection for grapevine improvement. Registering the newly identified varieties and somatic variants with novel traits of interest would represent a crucial first step toward making this plant material available to local grape growers, ultimately promoting the diversification of the Peruvian grape, wine, and Pisco industries.
