It is not overstated that Argentinean viticulture identifies with Malbec, the vine which long ago wasintroduced in the country from France and which has marvelously naturalized here. However, the variety Malbechas many different expressions, depending very much on environmental and cultivating conditions and on naturalmutations occurred over time. A modern viticulture cannot do without the capability of exactly identifyingand differentiating clones of the same variety and from the ability to do that over contingency. This work onclonal selection, conceived and developed by a very polyvalent team, focuses exactly on defining instruments tounequivocally distinguish and select different clones and using these instruments to analyze, classify and selectall different clones representing the highest variability of Malbec in Argentina ever sampled. The work baseson traditional instruments ? phenotypic and enological analysis ? and on a molecular marker selection program.Through the synergy of all these methods the team has come to the selection of 16 superior clones of Malbecand will proceed by sharing and mapping three of those clones on the country different micro-environments forgrapevine growing regions, giving Argentinean viticulture a key instrument to identify its most valuable grapewine variety.
