In the Tobacco Experimental Station in San Juan y Martinez, Pinar del Río, during the tobacco crops 2001-2002, was made the cross ‘Criollo 98’/‘Habana 2000’//‘Corojo 99’/‘L 17’, with the objective of obtaining a dark tobacco variety with more yield that the commercial ‘Criollo 98’. It is resistant to the blue mold (Peronospora hyocyami de Bary), black shank (Phytophthora parasitica Dast. var. Nicotianae Breda de Haan), tobacco mosaic virus (TMV) and weather fleck. After five generations of self-pollination and selection by the pedigree method, seven resistant varieties were obtained. The variety ‘Corojo 2012’ surpassed to ‘Criollo 98’ in total yield, yield of wrappers and production value.

Palabras clave : cross; blue mold; black shank; tobacco mosaic virus; weather fleck; varieties.
