Abstract
This work shows the results obtained by the Forest Experimental Station Viñales in the improvement and conservation of the genetic resources of Pinus caribaea Morelet var. caribaea. As a result of that work 537 plus trees have been selected and 15 tests of progeny have settled down in different type of soil and climatic condition, in which heritability values have been obtained in strict sense of 0.50.7 with advanced of the order of 10-20 in the yields woods and 15-40% in the oleoresin sweat. Four banks of clones and 220 ha of first generation clonals seed orchards were established. Finally with trees «élites» of well-known parents obtained by means of controlled crosses, the creation of clonal seed orchards of second generation has begun.
