Abstract: Tobacco is a principal cash crop of India. The present investigation was carried out to study the genetic parameters like gene effects, epistasis and linkages. The scaling test indicated the presence of epistasis for all the characters in different crosses except number of leaves per plant in Cross II, plant height in Cross II and capsule weight in Cross IV. The estimates of gene effects in Cross I reflected the involvement of additive gene effect in the expression of plant height, seed weight per capsule and test weight; whereas additive as well as non-additive gene effects were involved in the expression of days to flowering, number of capsules per plant, capsule weight, khakhri yield per plant and seed oil yield per plant. Whereas only non-additive gene effect was evident for number of leaves per plant, days to capsule maturity, seed yield per plant and seed oil percent.
