Since 1987 the CMA (Agricultural Improvement Centre) El Chaparrillo has conducted different activities to determine the real possibilities of adapting the pistachio tree (Pistacia vera L.) to the region of Castilla-La Mancha. During the ten-year period, the initial interesting theoretical expectations regarding its introduction have been confirmed in the experimental plots with studies on phenology, propagation, production, etc. In the region, there has been a significant and steady rise in farmers' interest in the crop. This was demonstrated by the fact that over the last two years almost 200 ha of Pistacia terebinthus L. have been sown in regular plantations, on which Kerman, Napoletana, Peter and 02-18 cultivars will be grafted in the next two years.
