“…However, in the present study variances due to GCA were much higher in magnitude than SCA for the characters of days to 50% tasseling and silking, ear height, ear length, number of grains per row and 1000-grain weight, which revealed the prevalence of additive gene action for controlling these traits. The predominance of additive gene action for days to tasseling, days to silking and number of grain per row was reported by Hoque et al (2016) which supports the present study. On the other hand, non additive gene action for ear height and 1000-grain weight was supported by Hoque et al (2016) and Kadir (2010).…”

“…On the other hand, the magnitude of SCA was higher than GCA for plant height, number of grain per row and grain yield, indicating non-additive gene action in controlling these traits. Non-additive gene action was also reported on plant height (Kadir, 2010), number of kernel per row (Abdel-Moneam et al, 2009) and grain yield (Abdel-Moneam et al, 2009;Kadir, 2010;Barakat and Osman, 2008;Gouda et al, 2013;Hoque et al, 2016) in their study. These investigations supported the present study.…”

“…This indicated the importance of both additive and non-additive components of genetic variance in controlling these traits. Importance of both GCA and SCA variances for yield and yield contributing traits in maize was reported in various previous studies Gurung et al, 2008;Mousa, 2014;Hoque et al, 2016). However, in the present study variances due to GCA were much higher in magnitude than SCA for the characters of days to 50% tasseling and silking, ear height, ear length, number of grains per row and 1000-grain weight, which revealed the prevalence of additive gene action for controlling these traits.…”

Twenty one F1s produced from 77 diallel mating along with the 7 parents were evaluated to notice the inheritance and combining ability of different traits to obtain high heterotic crosses. Genetic analysis and combing ability were analyzed following Hayman's and Griffing's diallel analyses, respectively. Hybrids projecting positive or negative potency ratio with >1.0 value for those traits is also the sign of incidence of over-dominance in desirable direction, and heterosis breeding is important to improve those traits in maize. Hayman's approach indicated dominance variance and the proportion of +/genes was higher than additive variance in all characters. Griffing's analysis also demonstrated the presence of over-dominance governing the traits. The preponderance of dominant gene action coupled with low heritability observed for days to silking, ear length and grain yield suggests the importance of heterosis breeding. Substantial differences in general combing ability and specific combining ability were noticed in all the studied traits except 1000-grain weight. The parental line CML-509 was found to be the best general combiner for days to tasseling and silking, CML-498 for plant height, ear height and grain yield, CML-395 for ear length and grain yield. The crosses CML-498×CML-376, CML-498×CML-395 and CML-376×CML-247 showed significant positive specific combining ability effect for grain yield along with higher mean values over commercial check varieties.

“…In the ACG x A and ACE x A interaction, only DFm and DFf showed highly significant differences (p≤0.01), in the two cultivation campaigns. The ACG/ ACE ratio was lower than unity in all the characters, being more influenced by the effects of ACG, in APt, DFm and DFf and contrary to this, AMz and Rto had a greater influence of ACE, this assertion is corroborated by several authors in similar investigations (Rovaris et al, 2014;Hosana et al, 2015) and with effects of additive genes on APt, DFm and DFf (Hoque et al, 2016;Begum et al, 2018) and non-genes additives on AMz (Hoque et al, 2016;Begum et al, 2018) and Rto (Abdel-Moneam et al, 2009).…”

The objective of the present study was to determine the general combinatorial aptitude (GCA), specific combinatorial aptitude (SCA) and heterosis in inbred lines of yellow maize and its crosses for, the yield of grain, height of plant and ear and days to male and female flowering. Six inbred lines from CIMMYT, their direct crosses and four controls were evaluated at UNALM during 2016-2018, under a 5 x 5 lattice design with four repetitions. The effects of GCA and SCA were calculated using method II, model I of Griffing. Heterosis was measured based on the mean and best parent. Heterosis was measured based on the mean and best parent. The combined analysis of years showed significance (p ≤ 0.01) in: genotypes by years for days to male and female flowering; GCA for years for days to male flowering and SCA for years for days to female flowering. The effects of ACG for grain yield were significant in lines CML 229 and CML 428, for plant height, precocity, ear and precocity CML 487 line highlighted. The effect of ACE was superior in the cross CML 453 x CML 486 for the grain yield character. Heterosis was higher for the grain yield in the CML 229 x CML 453 and CML 453 x CML 487 crosses. The GCA / SCA relationship evidenced effects of additive genes on plant height, days to male and female flowering, therefore, for grain yield and ear height, non-additive effects governed.
