The present application provides tobacco inbred plants dS1746, dS1746MS, dS1564 and dS1564MS. The present application also provides parts of such plants and products made from those parts. The present application also includes progeny of the provided plants including hybrids.

An oral tobacco product includes a body that is wholly receivable in an oral cavity. The body includes a mouth-stable polymer matrix and tobacco fibers embedded in the mouth-stable polymer matrix. The oral tobacco product can be formed by extruding a mixture of mouth-stable polymer and tobacco fibers.

A smokeless tobacco product is provided that includes a tobacco material in the form of a tobacco extract, a particulate tobacco material, or a combination thereof. In some embodiments, the smokeless tobacco product is substantially translucent. Methods for making and using the smokeless tobacco product are also provided. The smokeless tobacco product can include isomalt, maltitol syrup, particulate tobacco, and a translucent tobacco extract prepared by ultrafiltration.

A heat-conducting tobacco composition comprising at least one sort of tobacco in at least one confectioning of the tobacco for smoking tobacco consumption. The heat-conducting tobacco composition is configured or designed as a tobacco article for at least one smoking article selected from the following group: dry tobacco article for cigarettes, cigarillos, cigars, semi-dry tobacco article for smoking tobacco pipes, moist tobacco article for water pipes; wherein the heat-conducting tobacco composition further comprises at least one metallic, in particular noble metallic component which performs a physical heat-conducting function during smoking, in particular when exposed to heat by ember/glow or by heating elements of the smoking article, and which is chemically inert at least in the temperature range required for smoking, and which is admixed to the tobacco and distributed in the tobacco composition in such a way that the heat distribution within the tobacco composition is homogenized during smoking.
