Low maize yields due to low nitrogen generally occur on marginal land. Maize development in Indonesia is directed at marginal land due to limited fertile land, especially in other lands in Indonesia besides Java. Therefore, the assembly of low N tolerant maize varieties plays an important role in increasing production on marginal land. The improvement of low N tolerant hybrid maize was required. Information on the combining ability of inbred lines was important in the hybrid maize breeding program. This research aims were to determine genetic parameters, general combining ability, specific combining ability of maize lines and at three levels of N fertilization. This research was conducted at the Bajeng Experimental farm South Sulawesi from August to November 2019. The research was arranged in a split-plot design with two replications. The main plots were three nitrogen levels i.e. 0 kg N/ ha, 100 kg N/ha, 200 kg N/ha and the subplots were 36 hybrids formed from a half diallel cross and its parents. The results showed that compared to yield at 200 kg N/ha, yield at 100 kg N/ha and 0 kg N/ha reduced 18,80% and 38,69% respectively. ear number, ear weight, shelling percentage and number of seeds per row were controlled by non-additive genes, while moisture content, 100 seeds weight, ear length and number of rows per ear were controlled by additives gene. Lines AVLN 118-7 and AVLN 83-2 have good GCA for yield grain overall levels of fertilization. Crosses AVLN 83-2/AVLN 124-4, AVLN 83-2/AVLN 32-8, and AVLN 122-2/ AVLN 124-9 have the good combining ability under both low and high N conditions. They could be used to develop low N tolerant varieties.

“…Estimation of heterosis, potence ratio, gene actions, combining ability and reciprocal effects of yield and its components should be greatly emphasized for the improvement of this crop. One of the several biometrical techniques available to plant breeders to achieve abovementioned information in the crop species is diallel analysis (Seyyed-Nazari et al, 2016). Diallel crosses reportedly provided early information on the genetic behavior of these attributes in the first generation (Farshadfar et al, 2011(Farshadfar et al, , 2014.…”

“…They represent the best strategy for determining the general (GCA) and specific (SCA) combining abilities which help to identify the best parents and hybrid combinations and, provide sufficient genetic data about character inheritances (Farshadfar et al, 2011(Farshadfar et al, , 2014Iqbal et al, 2015;Farshadfar and Amiri, 2015;Chukwu et al, 2016;Golabadi et al, 2017). In fact, the significance of the GCA reflects additive gene actions while the significance of SCA reflects the non-additive genetic effects which indicates relevant non-allelic interactions (Hossein et al, 2014;Fasahat et al,2016;Seyyed-Nazari et al, 2016;Golabadi et al, 2017;Queiroz et al,2017;Santos et al, 2017). If both GCA and SCA values are not significant, epistatic gene effects may play a remarkable role in determining these characters (Farshadfar and Amiri, 2015;Fasahat et al, 2016).…”

For the estimation of genetic parameters (such as heterosis effect, potence ratio, combining ability and reciprocal effects) of five fruit traits, in order to suggest breeding strategies in Citrullus mucosospermus (Fursa), a field trial was carried out at Kononfla city in Western Côte d'Ivoire using 4x4 full diallel. All 12 F 1 hybrids and their parents were planted in a randomized complete block design with three replications. A positive heterosis effect relative to mid-parental values was observed to hybrids having one parent Bebu for characters' fruit weight, fruit diameter and fruit volume. Variances due to general (GCA) and specific (SCA) combining abilities were significant (P˂0.001) for all studied traits, indicating the involvement of both additive and non-additive gene actions in the inheritance of these traits. Non-additive gene effects were predominant for all studied traits. Bebu was the best general combiner for all traits except fruit number which the best combiners were three morphotypes of Wss. For NF, Wss1×Wss2 and Wss2×Wss3 recorded the highest positive SCA values. Crosses involving Bebu as one parent, presented the best SCA values for other traits.
