La vid (Vitis vinifera L.) fue introducida en Sudamérica durante el siglo XVI. En los valles de Ica y Cañete, los nombres "Quebranta Mollar", "Mollar" y "Prieta Mollar" son comúnmente utilizados en referencia a los diferentes colores de las bayas de estas variedades dentro de un mismo racimo. Esta heterogeneidad en cuanto al color de las bayas, sumada a los antecedentes históricos, sugieren que otras variedades, además de Quebranta y Mollar Cano, podrían estar implicadas en esta denominación genérica "Mollar". En este trabajo se identificaron diferentes fenotipos correspondientes a algunas variedades utilizadas en la elaboración de vino y Pisco. Para ello, 10 accesiones fueron recolectadas en 9 viñedos diferentes (valles de Ica y Cañete), y analizadas utilizando 20 marcadores moleculares y 25 descriptores morfológicos según la OIV. Nuestros resultados mostraron que las muestras recolectadas correspondieron a 5 genotipos, tres cultivares tradicionales y dos genotipos desconocidos no registrados previamente. Los tres cultivares conocidos fueron Listan Prieto, Quebranta y Mollar Cano. Las dos accesiones correspondientes a variedades no conocidas previamente fueron Mollar de Ica y Prieta Mollar, generadas a partir de retrocruzamientos entre Quebranta y sus progenitores. También se identificaron diferentes variaciones fenotípicas de Quebranta, lo cual enriquece la diversidad vitícola peruana.
Abstract
Grapevine (Vitis vinifera L.) was introduced in South America since the 16th century. In the Ica and Cañete Valleys, the names "Quebranta Mollar", "Mollar" and "Prieta Mollar" are commonly used in reference to different colors of the berries of these varieties within the same bunch. This heterogeneity in terms of berry color, added to the background of historical documents, suggests that other varieties, besides Quebranta y Mollar Cano, could be involved in this generic denomination of “Mollar” vines. This work identified different phenotypes corresponding to some varieties used in winemaking and Pisco. The 10 accessions were collected on 9 different vineyards in the Ica and Cañete valleys, and were analyzed using 20 molecular markers and 25 morphological descriptors according to the OIV. Our results showed that the collected sampled corresponded to 5 genotypes, three traditional cultivars and two unknown genotypes not registered previously. The three known cultivars were Listan Prieto, Quebranta and Mollar Cano. The two accessions corresponding to non-previously known varieties were Mollar de Ica and Prieta Mollar, generated from backcrosses between Quebranta and its parents. We also identified different phenotypic variations of Quebranta, which enriches the peruvian viticultural diversity.
