<p>MED-GOLD is an EU-funded Horizon 2020 project (https://www.med-gold.eu/) whose main objective is to demonstrate the proof-of-concept for climate services in agriculture by developing case studies for three staples of the Mediterranean food system: grapes, olives and durum wheat.</p><p>MED-GOLD will propose climate services deploying forecast information at seasonal (next 6 months) and long-term (next 30 years). This information will be provided at higher spatial resolution than what is currently available. To provide the highest value for decision-making, the services will be co-developed with professional users from each sector.</p><p>For the wine sector, the project objective is to use the most recent state-of-the-art climate models outputs to produce user-oriented predictions of essential climate variables, bioclimatic indicators  and ad-hoc implemented compound risk indices. All of these indices  are relevant for viticulture at large scales, and more specifically for the MED-GOLD focus region of the Douro valley (Portugal). The indices  will be readily available for users in the grape and wine sector under several different formats and visualizations, allowing for easy, quick and seamless integration into critical decision-making.</p><p>Timely warnings of when climate change might impose a disruptive pressure upon wine production systems offers stakeholders a chance to act proactively both at seasonal (operational campaign planning) and decadal (strategic business planning) time-scales, making the wine sector more resilient to the impacts of climate change.</p>

Grape Varieties

Preserving rare grapes is not just a matter of variety. Recent dna research has shown that unusual and unknown grape varieties provide clues to wine history. During the centuries, 525 Georgian grape varieties had been known but most of them were degenerated. Nowadays, more than 437 rare Georgian vine varieties are preserved in the geo 038 collection of Agricultural Research-Scientific Center, established in 2014 under the Environment Protection and agriculture ministry. Study of the genetic pool of Georgian grape varieties determine the sustainability of the sector and enrichment of the modern wine market. For this reason the studies of the rare aboriginal grape varieties have begun by their ampelography, phenology, chemical, and oeno-caprological characterizes. The aim of this study is to investigate rare, Georgian, aboriginal wine-grapes by their ampelography, chemical and oenolo-caprological characterizes, and to offer different style and aroma wines to the market, enriching the modern wine assortment. The present study investigated firstly the rare Georgian aboriginal grape variety (Chvitiluri) by its characterizes. In this study grapes caprologycal indication, dynamic development of the sugar accumulation, TA and pH in berries, polyphenols extract in skin and seeds, and phenolic compounds were determined. The grape has been compared with Georgian and French wine-grapes and their products as well. The results show that the grape variety - Chvitiluri, and vinification technique (aging on lee) have the significant impact on the total phenol content in wine. White varietal wine contents high alcohol 13,2%, total phenols 733-500mg/l. Wine has specific, varietal characterizes color, taste, aroma. This study indicates that the rare local, aboriginal variety presents the perspective sort for wine production and can be returned in wine production.

El objetivo fue estudiar la variabilidad genética de características morfológicas de maíces nativos en la Península de Yucatán (PY), México. Se utilizaron trece accesiones de maíz nativo reconocidas con el nombre de Naál Xóy, Xnúc Naál Blanco, Gallito Amarillo, Dzit Bacal, Mejeén Naál, Rosa San Juan, Cháck-Chóp, Teél Cháck, Sáck Teél, San Pableño, Ejú-Criollo Morado, Xmején Naál Tsitbacal y Clavo Chiapaneco. Los materiales se establecieron en Junio de 2017 y 2018, en Poxyaxum, Campeche, México, (19° 41´58.4´´ N, 90° 21´03.6´´ W y 30 msnm) bajo un diseño de bloques completos al azar con tres repeticiones. Los resultados revelaron diferencias (P£0.05) en las variables morfológicas evaluadas: número de días a floración masculina (FM) y femenina (FF) presento una inestabilidad de 12 días a FM y FF, con Naál Xóy y Ejú-Criollo Morado, y 15 días a madurez fisiológica con Clavo Chiapaneco. Una diferenciación de 98 y 126 cm en altura de mazorca y planta con Eju-Criollo Morado; 6 y 1.1 cm en longitud y diámetro de mazorca con Xnúc Naál Blanco y Cháck-Chóp, y Gallito Amarillo. Una variación de 4 hileras con Teél Cháck y 17 granos por hilera con San Pableño; 11 y 74 gr en peso de 100 granos (Xmején Naál Tsitbacal, Rosa San Juan y San Pableño) y granos por mazorca (Naál Xóy); y una diferencia mayor en rendimiento con Naál Xóy y Dzit Bacal de 3105 kg.ha-1.
