RESUMEN

Según la Lista de Sander´s, dirigida por la Sociedad Hortícola Real, responsable del registro de orquídeas híbridas, existen más de 10 000 híbridos registrados en el mundo. En Cuba se cuenta con más de trescientas veinte especies nativas y autóctonas y un solo híbrido de orquídea Spathoglottis «Bella Lorena». En este trabajo se presentan las características principales de un nuevo cultivar de orquídea epifita, obtenido por el Instituto Nacional de Ciencias Agrícolas (INCA), provincia Mayabeque. Catyclia «Free the Five», es el resultado de la polinización manual cruzada realizada en mayo de 2003, entre Cattleya leuddemanniana y Encyclia phoenicea, las semillas híbridas fueron germinadas mediante el cultivo in vitro y las primeras plantas comenzaron a florecer en julio del 2010 después de siete años de cultivo. Actualmente se encuentra publicado en Orchids Review Supplement 119 (1293): marzo 2011.

In Cuba we have approximately more than three hundred twenty native species and wild orchids and only one Spathoglottis «Bella Lorena» hybrid. This article presents the main characteristics of a new hybrid of epiphytic orchids; obtained at the National Institute of Agricultural Science (INCA), Mayabeque province. Catyclia «Free the Five» is the result of a manual pollination between Cattleya leuddemaniana and Encyclia phoenicia, the hybrid seeds were germinated in vitro and flowering occurs on June 2010, after seven years of planting.
