Eight triticale strains, selected on the basis of morphological variation, fertility and homozygosity, were tested for their combining ability, using a diallel cross technique. Significant genotypic differences were observed among these strains and their hybrids for all the characters except 100-grain weight. In general, gca variances were higher than the sca variances. Considering all the characters together, strains 6TA204, St 69–1 and T 125 were good general combiners while TCL 3 was a poor general combiner. Per se performance of the parents and hybrids was observed to be associated with gca and sca effects respectively. Implications of the results obtained from this study for the improvement of triticale have been discussed.
