Abstract
El estudio se ejecutó en el distrito y provincia de Caravelí, región Arequipa, Perú, donde se cultivan diferentes cepas de uva (Vitis vinifera L.) a los cuales se realizó la prospección, análisis genético y ampelográfico, con la intención de proteger y revalorar el recurso vitícola local. La cuantificación de individuos se llevó a cabo por cada cepa y se identificaron según el nombre local utilizado. Para el análisis genético se seleccionó muestras vegetales de brotes jóvenes, de las plantas cultivadas en la zona de estudio, se le extrajeron estacas, que fueron inducidas a brotar, se tomaron los ápices de crecimientos y hojas jóvenes, se consideraron 2 por variedad, y se examinó a través de marcadores moleculares mediante PCR. Se referenciaron, en total 11 de diferentes parras. En el Laboratorio de Biotecnología de la Universidad Nacional Agraria La Molina se recolectó el ADN, para luego ser llevado al Laboratorio de Postcosecha INIA Chile, donde se hizo el levantamiento de perfil genético, generado en base al genotipado con 27 marcadores SSRs. A su vez se procedió a la determinación de identidad con base de datos local y con VIVC (Vitis International Variety Catalogue). Además, se creó un diagnóstico secundario de cálculo de distancias genéticas para estimación de relaciones entre el universo de accesiones y material reportado por publicaciones internacionales. Se elaboraron los registros morfológicos de 8 cultivares tradicionales teniendo en cuenta 24 caracteres ampelográficos, de acuerdo con el Segundo Catálogo de la OIV.Y se produjo una evaluación vinifica de 3 vides nuevas encontradas.
The study was executed in the district and province of Caravelí, Arequipa region, Peru, where different grape strains (Vitis vinifera L.) are grown, to which prospection, genetic and ampelographic analysis were carried out, with the intention of protecting and revaluing the local wine resource. The quantification of individuals was performed for each strain and they were identified according to the local name used. For the genetic analysis, samples of young shoots were selected from the plants grown in the study area, cuttings were extracted, which were induced to sprout, the apices of growth and young leaves were taken, 2 were considered per variety, and examined through molecular markers by PCR. A total of 11 of different vines were referenced. In the Biotechnology Laboratory of the National Agrarian University La Molina, the DNA was collected, and then taken to the INIA Chile Postharvest Laboratory, where the genetic profile was raised, generated based on genotyping with 27 SSR markers. In turn, identity was determined with a local database and with VIVC (Vitis International Variety Catalogue). In addition, a secondary diagnosis of calculation of genetic distances was created to estimate relationships between the universe of accessions and material reported by international publications. The morphological records of 8 traditional cultivars were elaborated, taking into account 24 ampelographic characters, according to the Second Catalogue of the OIV. And there was a vinifical evaluation of 3 new vines found.
