Abstract: A set of 4 4 diallel crosses in wheat was analysed for combining ability of traits like number of tillers per plant, spike length, number of grains per spike and 1000-grain weight. The mean squares for general (GCA) and specific combining ability (SCA) were highly significantly for number of grains per spike and 1000-grain weight. The reciprocal effects were also highly significant for all traits under study except spike length which was non-significant. The additive gene effect controlled the expression of number of tillers per plant and 1000-grain weight as is evidenced by greater components of variance for GCA. Non-additive gene effects controlled the expression of spike length and number of grains per spike as is apparent by greater components of variance for SCA. Variety Pitic 62 was considered to be good general combiner for spike length, number of grains per spike and 1000-grain weight.
