The research was conducted to assess the combining ability in respect to leaf yield and its component characters through 6 x 6 diallel mating design involving thirty hybrids and six parents in FCV tobacco during kharif 2016 at ZAHRS (Zonal Agricultural and Horticultural Research Station), College of Agriculture Shivamogga. Combining ability analysis was carried out for leaf yield and its components in FCV tobacco. Both General combining ability (GCA) and Specific combining ability (SCA) variances were highly significant for almost all the characters. Parents and F1 hybrids differ significantly for GCA and SCA effects for all the characters respectively. Study on the combining ability revealed that the parents Kanchan, FCH-222 and Tobios-6 were found to be best general combiners for cured leaf yield than others. The highest significant positive SCA effects was observed in the cross 2 x 4 followed by 1 x 3, 6 x 1, 1 x 4 and 1 x 5 for cured leaf yield. These hybrids were found to be suitable for obtaining higher cured leaf yield in FCV tobacco.
