A process for producing a reduced tobacco-specific nitrosamine (TSNA) tobacco plant comprising reducing and/or eliminating anatabine biosynthesis in wild-type tobacco plant. In addition, use of such plants for discovery of molecular markers that are closely linked with genes required for anatabine biosynthesis and for discovery of genes required for anatabine biosynthesis. In addition, a smoking composition, a smoking article and a smokeless tobacco oral delivery product contain the tobacco material.
