Maize inbred lines were evaluated by using line × tester method involving 11 lines and 3 testers for grain yield and its components through estimation of general combining ability (gca) and specific combining ability (sca) effects. Highly significant genotypic differences were observed indicated wide range of variability present among the genotypes. The crosses with high sca effect for grain yield were evolved from high × low general combiner parents which reveled additive × dominance type of gene action. The cross combinations 9MS4-1 × L22, 9MS4-1 × L486, 9MS4-2 × L431, 9MS4-11 × L486 and 9MS4- 15 × L431 with high positive sca effect having high mean values might be used for obtaining high yielding hybrids. The information on the nature of gene action with respective variety and characters might be used depending on the breeding objectives. DOI: http://dx.doi.org/10.3329/bjar.v39i4.22547 Bangladesh J.

Six inbred lines (Syn-1, MGW-3, S-165, Syn-22, Zm-9, M-17)  of maize (Zea mays L.) were used in this study using half diallel cross and developed 15 F1 single crosses . The single crosses were crossed a ccording to Rawllings and Cookerham method and developed 45 double crosses . Seeds of double crosses were cultivated to study combining ability and gene action of the parent. The results showed highly sinificant differences for mean square of double crosses and for the some  traits . The double crosses (Syn-1* ZM-9)(MGW-3 * M-17) , (Syn-1 * ZM-9)(S-165 * Syn-22) , (MGW-3 *M17)(S-165 *Syn-22) , (Syn-1 *S-165)(MGW-3*Syn-22) (Syn-1 *S-165)(ZM-9* M17) and (MGW-3 * Syn-22)(ZM-9 *M-17) revealed highest specific combining ability effects for leaf area , number grains.ear-1and grain yield gms.plant-1 . All characters were under the epistatic gene effect with type of gene action (Dominance * Dominance) except leaf area was under the type of gene action (Additive*Dominance).
