Varieties of Tobacco Diversities that are created to have greater productivity in the harvest . Some varieties obtained are Habana 92, Habana 2000 , and Criollo 98 among others.
Variety Havana 92
The variety Habana 92 is the product of a cross between the Corojo variety of Cuban origin and the Polish variety R x T, from which it inherits the resistance to the Blue Mold or Peronospora tabacina Adam .
Cultivated in the sun it has a height with inflorescence between 160 and 170 cm, with a variable number of useful leaves which, depending on the soil where it is grown, can range from 14 to 18 cm, with an average internode distance of 7 cm. The maximum width of these leaves can be between 20 and 25 cm, with an average length of 40-45 cm. The leaves are also characterized by their bright green color and by being very narrow at the base (little beard).
The average yield potential of this variety in the harvest of the main leaves is around 500 qq / cab and the sun in stick, with only a good cut of layers, in brown soils can average about 800 qq / cab, as practical potential means of performance. It is resistant to blue mold, to the Black Shank (Phytophthora parasitica var. Nicotianae), to environmental necrosis and tolerant to Orobanche ramosa L. It is recommended for sun cultivation and collection in leaves or dumbbells.
Variety Havana 2000
This variety arises from a cross between the Corojo variety and a non-commercial variety of Cuban black tobacco, Havana 2.1.1 , from which it inherits resistance to blue mold. The Havana 2000 cultivated in the sun reaches an average height with inflorescence between 170 and 180 cm, with 14-16 leaves per plant.
Although in very rich soils can develop up to 18 leaves per plant. The average distance between the leaves is of 7 cm and the length and average width of the greater leaf varies between 48-52 cm and 24-28 cm, respectively. It has an average agricultural yield potential of about 500 qq when grown in the sun and harvested in leaves and about 750 qq net when grown in the sun and harvested by dumbbells. Cultivated in the sun and harvested in leaves, it presents a high performance in capes. It is highly resistant to brown feet [?root rot?], resistant to blue mold and moderately resistant to environmental necrosis. It is recommended for cultivation under cloth and for cultivation in the sun. Under certain conditions, it can also be used to cultivate the sun in stick.
Variety Criollo 98
It originates from a cross between the varieties Habana 92 and Habana PR. Cultivated to the sun it develops 14-16 useful leaves per plant and reaches an average height with inflorescence of 150-160 cm, given this small height to the fact that it has a distance of medium internodes of only 5 cm, aspect that distinguishes it from the rest of the Cuban black tobacco varieties. The greater leaf presents an average length of 48-52 cm and a width of 24-28 cm. Its average potential yield, cultivated in the sun, is about 500 qq / cab and the sun in a stick of 800 qq net / cab.
It is resistant to blue mold, brown paw [?root rot?] and tobacco mosaic virus and moderately resistant to environmental necrosis. It is recommended for cultivation under cloth , the sun strung and the sun on stick. Cultivated in the sun strung has high performance in wrapper.
Variety Corojo 99
It is sister of the variety Criollo 98 , that is, it originated from the same cross between the varieties Habana 92 and Habana PR Cultivated to the sun it presents a height with average inflorescence, of 160-170 cm, with 14-16 useful leaves per plant. The dimensions of the greater blade are between 48 and 52 cm for the length and 24-28 cm for the width.
The average distance between the leaves is 7 cm. Its potential agricultural yield is about 500 qq / cab, with a high percentage of wrapper when grown in the sun. It is resistant to blue mold, black shank, tobacco mosaic virus and environmental necrosis. It is recommended for cultivation under cloth and in the sun.
Other varieties of black tobacco grown in Cuba
Variety Havana Vuelta Arriba
It was obtained from a cross between the Corojo variety and the Australian variety GA-955 , from which it inherited the resistance to blue mold. It presents an average height with inflorescence between 180 and 190 cm, with a number of useful leaves per plant from 14 to 16 and an average distance between them of 8 cm. The average dimensions of the greater leaf are of 43-48 cm for the length and of 28-30 cm for the width.
Its average potential yield cultivated in the sun is about 550 qq / cab and cultivated in the sun on stick, about 900 qq net / cab. It is resistant to blue mold, black shank, tobacco mosaic virus and moderately resistant to environmental necrosis and Rhizoctonia solani. It is recommended for crops in the sun strung and sun on stick.
Variety Sancti-Spíritus 96
Its progenitors are the variety Pelo de Oro and the Polish variety R x T, from which it inherits its resistance to blue mold. It presents an average height with an inflorescence of 145-155 cm, with 12-14 useful leaves per plant and an average distance of internodes of 8 cm. Its average potential yield is about 800 qq net / cab, given in the fundamental, for its high performance in layers. It is resistant to blue mold, black shank, and environmental necrosis. It is recommended for sun cultivation on stick.
