The study of gene effects for eight quantitative traits in three crosses of bidi tobacco using generation mean analysis revealed that Gross 2 had predominantly additive effects for leaf number and plant height, while for days to maturity dominance, dominance X dominance and additive X dominance effects were observed. Additive as well as its first order interaction with dominance were observed for cured leaf yield. In Gross 3, additive effects were observed for leaf number, leaf area and cured leaf yield, while for plant height additive as well as additive x additive effects were observed. Days to maturity trait had additive as well as its first order interaction and dominance X dominance effects. Hence pedigree method of breeding would be better for the improvement of yield. In case high yielding genotypes are to be bred for rainfed farming, cyclic method would be a good choice.
