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.

In China, there are increasing needs for greater genetic diversity of maize (Zea mays L.) germplasm and for hybrids appropriate for machine harvesting. to test and distinguish American maize inbred lines with exceptional combining ability, Four Chinese maize inbred lines (Chang7-2, Zheng 58,four-144 and four-287) were used to judge combining ability and heterosis of 16 U.S.A inbred lines by a NCII genetic mating method. The result showed: Among the American inbred lines, 6M502A,LH208,NL001,LH212Ht,PHW51,FBLA and LH181 showed excellent GCA for yield characteristics; while RS710,PHP76,FBLA,and PHJ89 showed excellent GCA for machine harvesting characteristics. In hybrid combinations, NL001×Chang7-2,LH212Ht×Chang7-2,FBLA×four-144,LH181×four-287,PHK93×four-287 had better SCA for yield characteristics; while NL001×Chang 7-2,6M502A×Chang7-2,LH212Ht×Chang7-2,LH181×four-287,PHW51×Chang7-2 were better than the check for machine harvesting characteristics. NL001×Chang7-2, 6M502A×Chang7-2,LH212Ht×Chang7-2,LH181×four-287,PHW51×Chang7-2 showed excellent total combined advantages compared to the check and potential for future utilization in Inner Mongolia corn production.
