The Castilla-La Mancha Vine and Wine Research Center (Ivicam), dependent on the Community Board, has planted a new experimental vine plot. The objective goes through mitigate the negative impact of climate change in the growth and development of the vine, as well as in the quality of the grape, with an eye to the possible adjustments necessary in the viticulture of the future.
The Minister of Agriculture, Water and Rural Development, Francisco Martínez Arroyo, explains that the experimental plot will serve to «see the effects of the restrictive and efficient use of water in the vineyard, in such a way that we improve the productive performance by using the most important resource we have, which is water ». To do this, the genotypes best adapted to the new environmental conditions will be identified, to also cope with the drought, looking for the most efficient varieties from the water point of view or those that best fit agronomically to the viticulture of Castilla-La Mancha.
The research includes a small group of patterns that could contribute to plant adaptation, improving it. A new 1.8 hectare plot has been installed on the Ivicam grounds, in Tomelloso, which has up to 24 varieties, half white and the other half red, and five patterns, resistant to drought and high concentrations of active limestone in the soil, with an average of 1,815 vines per hectare. In this plot, strategies of controlled deficit irrigation or partial drying of roots will be carried out in the coming years, within the line of research.
Martínez Arroyo indicates that «we want in this way, from the wine sector, to fight against climate change and adapt to the new reality in which it must be possible to maintain our ecosystems, our wetlands and, at the same time, make our wine sector be profitable. ‘
This new plot joins the three existing ones in the facilities of this center of reference of the vine and the wine, in which there is a collection of 174 varieties of vine of Castilla-La Mancha; the demonstration field of all the vine varieties authorized in Castilla-La Mancha to date, which is offered to winegrowers so that they know the characteristics of each one of them; as well as a third in which studies of irrigation management and type of season are already being carried out, with twelve varieties and four repetitions.
