An 8x8 diallel analysis was done for determining the combining ability for different agronomic characters in alfalfa (Medicago sativa L). Combining ability analysis revealed that number of tillers/plant, leafiness, yield of green mass/plant, yield of dry matter/plant, protein content in dry matter (%) and seed yield/plant were controlled by both additive and non-additive gene action. The gca variances were higher than the sca variances for the character studied indicating non-additive gene action in the present materials. There was a direct relations between the performance of hybrids and their sca effect in a majority of the ca The cross between the two best general combiners did not have high sca effect in cases. Only high x low and low x high cross combinations gave the best sca effect most cases. The parent Bordsckaya mestnaya was the best combiner for leafine yield of green mass/plant and yield of dry matter/plant, while AUPX for proteins content in dry matter (%) and seed yield/plant, and K-36614 appeared as best parent for number of tillers/plant.
