GARCIA-QUINTANA, Y.; ALVAREZ-BRITO, A.  e  GUIZAR-NOLAZCO, E.. PROVENANCE TRIALS OF Pinus caribaea var. Caribaea IN THE PIZARRAS HIGHLANDS, VIÑALES, PINAR DEL RIO, CUBA. Rev. Chapingo ser. cienc. for. ambient [online]. 2007, vol.13, n.2, pp.125-129. ISSN 2007-4018.

This work was carried out as study of case in the ambient of Viñales, Pinar del Rio, Cuba with the objective of selecting genetic material with special value for the conservation and improvement of the species from nine provenances, finding important differences among origins for the variable height, diameter and branching. The provenances were classified into A,B,C and D quality groups, recommending group A and B for development of the species at this place of extreme poor fertility. The variation coefficient was from 29.5 and 44.8 % should be total height and diameter were the most variable, so selection should be on the base of this characteristics, selecting as superior origin Marbajita, Cajálbana, El Burén, Los Palacios, La Jagua, La Güira and Juan Manuel.

Palavras-chave : conservation; tree improvement; provenances; variability.
