An approach to the model for conservation of Central Mexico native grapevines

Abstract

Several and diverse native populations of wild grapevines have been reported growing in the States of Puebla, Mexico and Morelos, Central Mexico. After collection, successfully rooted vines were planted in Zumpahuacán, State of Mexico, and since 2013, their fruit were analyzed, mainly in relation to berry-weight and sweetness. Recently, the seed oil content was analyzed. Most berries harvested in 2013, 2014 and 2015 weighted less than 1 g and only berries of accession Puebla-41 (P-41) weighted nearly 2.5 g. On the other hand, most berries had lower than 18°B. Four accessions, three native of Puebla and one from Morelos had the higher fruit production (2.5, 1.5 and 1.4; and 0.68 kg per plant) and might be the genetic material proposed to be planted in Zumpahuacán, Mexico. Seed oil analysis confirmed the presence of linoleic acid as the main fatty acid in Central Mexico wild grape seed oil. Nowadays, the extraction of seed oil in Central Mexico native grapes seems to be the better alternative to interest locals and agro-industrial related companies in conserving and cropping this plant genetic resource.

Environmental Conditions, and Phenolic Compounds Potential in the Leaves of Vitis Tiliifolia

“…The devastation of forests and jungles has diminished the population of V. tiliifolia. Speci c information, on the geographical distribution and dispersion of V. tiliifolia is scarce (Sabás-Chavez et al, 2018;Franco-Mora et al, 2008).…”

The Genetic Diversity of Wild Grapes in Mexico

“…Genetic studies have shown that wild germplasm from Mexico is a valuable resource for resistance to Pierce's disease, and a wide range of nematodes (Riaz et al 2018b;Riaz et al 2007;Xu et al 2008). Changes in land use, the expansion of urban areas, animal grazing, altered water rights and uses have led to deforestation, and great reductions in natural habitat and erosion of genetic diversity (Sabás-Chavez et al 2018). The Vitis species of Mexico represent a diverse and inadequately studied germplasm resource, whose conservation is important for grape breeding, cultural heritage studies and understanding of their role in the ecosystem.…”
