Importance of the fitogenètics resources|appeals
The fitogenètics resources|appeals are part of what we call biological diversity. It|He|She is in this diversity where the life is sustained in this planet. The foods, the medicine plants|floors, are the trees and plants|floors that bring us materials for the construction, for the clothing and other services, are the numerous microorganisms (Álvarez, 2000; Souza et al, 2001).
From the second half of the 20th s. reality starts to be the worry for the loss of the genetic diversity in the area of the agriculture. The implantation of improved vegetal crops|growings was one of the great successes of the green revolution, and together with the mechanization, the use of fertilizers and the chemical fight, allowed considerable increases of the agricultural productivity. But the substitution|replacement of the crops|growings and local varieties for the new improved crops|growings has meant an extraordinary loss of the genetic diversity (Frankel & Hawkes, 1975).
From several areas of the science, the resistance to|in plagues and illnesses, the nutritious quality and the productivity, alert fitogenètics, who|which are the irreplaceable source|fountain of characteristics as|like the adaptation to environmental conditions for us about the need to preserve the resources|appeals.
The local and traditional varieties
The local or traditional agricultural varieties are those that have been selected and improved along generations of farmers families, and are perfectly adapted to|in the local conditions of the zone in which they have developed (Domínquez, 1999). The local varieties are subject necessarily to a determinate, more or less extensive geographical location depending on its|his|her|their use. The great advantage of the local varieties is due to|in its|his|her|their heterogeneous origin and to|in the special adaptation to the concrete conditions of the agroecosistema that has generated them. These varieties are at the same time stable and flexible in the face of the environmental disturbances, which interest in the agricultural systems is of maximum that the agroquímics products do not use (Guzmán et al, 2000).
The fitogenètics resources|appeals are a heritage|patrimony of the humanity of incalculable value, and its|his|her|their loss is a process without reverse gear that means a great threat for the stability of the ecosystems, the agricultural development and the alimentary world security|certainty (Martín, I., 2001).
The Balearic Islands and its|his|her|their agricultural wealth.
The Balearic Islands, as a Mediterranean insular territory, have lived the presence of several cultures along the history|story as|like the Phoenicians, the Greeks, the Romans or the Arabs. This cultural diversity has configured the wealth of the Balearic culture, and in particular the agricultural tradition, which has numerous local varieties of fruit trees of sweet fruit, dried fruit and nuts, vineyard, olive trees, citrus, horticultural crops|growings, cereals, pastures and pulses.
