In the Tobacco Experimental Station in San Juan y Martinez, Pinar del Río province, during the tobacco crops 2001-2002, was made a sexual cross with the objective of obtaining a dark tobacco variety of tobacco with more yield that the commercial ‘Criollo 98’, resistant to the blue mold (Peronospora hyocyami de Bary), black shank (Phytophthora parasitica Dast. var. Nicotianae Breda de Haan), tobacco mosaic virus (VMT) and weather fleck. After five generations of self-pollination and selection by the pedigree method, seven resistant varieties were obtained. The cross originated the new variety `Corojo 2006´ that it surpassed the `Criollo 98´.
