A half diallel making design was used to determine combining ability and heterosis of six chickpea lines and their hybrid combinations with R.C.B.D. in three replication for seed yield per plant, number of pods per branch, pods number per plant, first pod height and 100- seed weight, during 2015 and 2016 seasons, at the research Center of Al-Gab (G.C.S.A.R). Genotypes, general (GCA) and specific (SCA) combining ability mean squares were significant for all studied traits. The ratio σ2 GCA / σ2 SCA were detected for all traits and showed that non- additive gene action was more important than additive gene action in controlling all studied traits. GCA effects showed that the lines الإسباني was good general combiner for traits:seed yield per plant, pods per plant, 100- seed weight, days to maturity, protein per cent. SCA effects showed that(Algerian×Spanish) hybrid was the good specific combiner for seed yield per plant, pods per plant, 100- seed weight, harvest index. On the other side(Algerian×Spanish) was showed significant desirable heterosis values for seed yield per plant and 100- seed weight, days to maturity, harvest index.
