The Rootstock Mother Plants grown by VCR members in an area covering 1,050 hectares of rich soils rich in skeleton and another 30 hectares in Greece, in order to increase the availability of the rootstock types 110 R, 1103 P, 41 B and 140 Ru. With regard to the scions, in addition to the plantations operated by members of the Cooperative, others are managed through cultivation contracts with farms located in the more renowned wine-growing regions. Since 1996, Vivai Cooperativi Rauscedo has established special plantation facilities for Scion Mother Plants over 50 hectares in Grado on the Adriatic coast, and 30 hectares in 2003 in Romagna at Cooperativa Valbruna’s, planting at these locations the best VCR and other Italian and foreign clones.
Over 700 Italian and foreign clone varieties are grown in Grado and new wine grape varieties resistant to diseases, selected by the University of Udine and by IGA (Institute of Applied Genomics), are currently being experimentally tested. From these vines in 2012, we have obtained the first production batches and subsequent microvinification with results in terms of quality that are fully comparable to established wines deriving from the most widespread varieties. As soon as these vines are enrolled in the national catalogue and cultivation is authorized in the different viticultural areas, we shall produce vines with a high level of environmental sustainability. In these virgin lands, clones are grown under a strict pest management protocol in order to maximize the production of healthy and well lignified scions.
Every year the fields of the Rootstock and Scion Mother Plants are inspected by the Plant Protection Service to verify the maintenance of the health status in compliance with the current regulations (Ministerial Decree February 8, 2005 and Ministerial Decree July 7, 2006 transposing the European Directive 2002/11 EC of February 14, 2002). In addition to these institutional checks, VCR performs its own health checks that do not stop at just visual symptoms: every year the laboratory of VCR Experimental Centre performs approximately 20,000 ELISA tests to ensure compliance with the health standards stipulated in the current laws regarding commercial grafted vines.
