The mode of inheritance, gene effect, combining ability and genetic components of variance for length of spike, number of spikelets per spike and number of kernels per spike in 4 divergent cultivars (Srbijanka, Partizanka, KG-56 and PKB-111) were studied in diallel crosses (without reciprocals). Cultivars and F2 hybrids showed great differences for the analyzed traits. This study showed that the mode of inheritance for all analyzed yield components was different with preponderance of partial dominance. The best general combiner for length of spike was Partizanka cultivar, while for number of spikelets per spike and number of kernels per spike it was Srbijanka cultivar.
