| Abstract | ||||
| Complete diallel set of 7 inbred, 21 single crosses and 21 reciprocal crosses were used for this study. The four methods of Griffing 1956 computed to obtain general combaining ability (G.C.A),spicific combining ability (S.C.A) and reciprocal effects for six characters. Grain yield (ard/fed), silking date, plant height, ear height, resistance to late wilt and resistance to downy mildew diseases were recorded. Generally, the results based on mean (x), coefficient of variability (C.V) experimental error (cr2e) and appropriate G.C.AlS.C.A mean square ratio emphasized that method - 4 was suitable in the case of diallel study for all studied traits, while the results optioned depending on including G.C.AlS.C.A ratio revealed that method -3 including single crosses and their reciprocal gave similar results with respect to gene action | ||||
