          Abstract

          RESUMEN En la Estación Experimental del Tabaco de San Juan y Martínez, Pinar del Río durante la campaña tabacalera 2001-2002, se realizó el cruzamiento ‘Criollo 98’/‘Habana 2000’//‘Corojo 99’/‘L 17’, con el objetivo de obtener una variedad de tabaco negro con mayor rendimiento que la comercial ‘Criollo 98’, resistente al moho azul (Peronospora hyocyami de Bary), a la pata prieta (Phytophthora parasitica Dast. var. Nicotianae Breda de Haan), al virus del mosaico del tabaco (VMT) y a la necrosis ambiental. Después de cinco generaciones de autofecundación y selección por el método genealógico se obtuvo siete variedades resistentes. La ‘Corojo 2012’ superó a la ‘Criollo 98’ en rendimiento total, en capas y en el valor de la producción.
