Abstract
Tobacco (Nicotiana tabacum L.) belongs to Solanaceae family. It
is a principal cash crop of India, earning a large share of the excise
revenue and giving employment to large number of people. Therefore,
concerted efforts are needed to genetically enhance this crop for various
qualitative and quantitative traits. As a small step in this direction, an
experimental material comprising of twelve females consisting of four bidi
tobacco varieties each with three cytoplasmic sources from allied species
viz., N. megalosiphon, N. undulate and N. tabacum and four males (testers)
was used in the study. The females were crossed with the pollinators in a
line x tester mating design. The resulting 48 hybrids along with 16
