One bold-and five small seeded varieties/lines of lentil were crossed to make a half-diallel. Combining abilities were calculated and both additive and nonadditive gene actions were found to be important in the expression of 100-seed weight and seed yield/plant in lentil. The per se performance of parents gave fair indication of their gca effects for 100-seed weight. One bold- and two small seeded parents had high seed weight besides being good general combiners for this trait. Only one parent KL 86-2, was found to be a good general combiner for seed yield/plant and also having significant positive gca effects for both the traits. Significant sca effects for 101-seed weight were recorded in the crosses involving one parent with high and the other with low gca effects.
