“…Iqbal et al (2007) showed significant specific combining ability and also found that non additive genes were more important for traits as number of kernels per ear, 1000 grain weight and number of kernels per row in maize. Aliu et al (2008) reported that leaf area was under the control of additive and non-additive genes and also concluded that if GCA of inbred lines was higher than SCA of these inbred lines might be higher or might not be higher. Akbar et al (2009) reported that the inheritance of some traits was controlled by non-additive genes like grain yield.…”

Crop production worldwide is focus to increasing environmental limitations, particularly to drought due to its high degree of impact and wide distribution. Conventional breeding approaches are trying to improve abiotic stress tolerance in crop plants, which have had some improvement, but are restricted by the quantitative nature of the traits. Maize is an important cereal crop. It is used as raw material in food, medicine and textile industries for the manufacturing of corn oil, corn flakes, dextrose, textile dyes livestock and poultry. Drought seriously affects plant growth from seedling to maturity. Mutation also proved to be tremendously important for evaluating functions for individual drought tolerant genes due to the availability of knock-out mutants and its docility for genetic transformation. To produce hybrids it is needed to collect information about germplasm diversity, combining ability and heterotic pattern that is essential in maximizing the effectiveness of the breeding programs. It will be helpful in selection of genotypes with improved yield. When genes for resistance to a particular disease or stress cannot be found in the available gene pool then mutation induction is the best alternative. In this review, the response of plant to drought and mutation are described, the regulatory routes which allow plants to manage with drought are presented, and how the present information can be useful to obtain stress tolerant plants.

“…For a hybrid to be useful to farmers in the wider environment, it has to be tested for its yield stability across locations (de Mattos et al, 2013). Studies of combining ability have been extensively used in assessing gene action associated with disease resistance and traits of economic importance in various crops including maize (Aliu et al, 2008;Nyadanu et al, 2012;Azad et al, 2014;Beyene et al, 2017;Chikuta et al, 2017). A set of Superior BC3F2 lines (with 93.5% homozygosity) and doubled haploid (DH) lines of maize were developed for resistance to MLN using foreground marker selection at CIMMYT, Kenya.…”

Combining ability studies have been extensively used to assess gene action responsible for various traits including disease resistance in maize. Some backcross (BC 3 F 2 ) and dihaploid (DH) lines developed through marker assisted selection have not been tested for their yield performances in hybrid combinations. A total of 16 BC 3 F 2 lines and their parental checks and 60 DH lines including lines and their parental checks were crossed to two single cross testers (CML312/CML442 and CML395/CML444) using Line x Tester design. The 152 three-way hybrids generated were evaluated for yield performance and other agronomic traits under artificial MLN inoculation, low nitrogen soil and optimum conditions in Kenya and South Sudan in 2019. Significant genotype, GxE, general combining ability (GCA) and specific combining ability (SCA) effects ( p ≤0.01) were detected for grain yield (t/ha) and maize lethal necrosis (MLN) scores. GCA effects were preponderant over SCA effects for most traits. High broad sense and moderate narrow sense heritability estimates for all traits across management options were detected. This implied that these traits could be improved through recurrent selection. DH lines D3, D14, D57 and BC 3 F 2 lines BCL3, BCL5, BCL8 showed desirable GCA effects for MLN resistance and grain yield. DH derived hybrids DH70, DH43, DH18 and DH40; and backcross (BC) derived hybrids BH28 and BH01 demonstrated desirable SCA effects for the same traits. Deployment of these MLN resistant lines into breeding programmes should result into improved MLN resistance and increased grain yields. The superior hybrids will provide desirable options for farmers who continue to experience low average maize yields due to MLN infections.

“…The share of hybrids was 4 % in the 1960's and already at 90 % in the early 2000's due to their high yield potential. Studies of specific combining abilities of inbred lines and physiological traits of some hybrids were already performed in agroecological conditions of Kosovo (Aliu et al, 2008(Aliu et al, , 2010. Maize became widely investigated plant species regarding different applications; its water use efficiency (Wang et al, 2013), morphological, physiological and biochemical response to SiO 2 nanoparticles (Sharifi-Rad et al, 2016), different irrigation regimes and planting methods (Singh Brar et al, 2016).…”

<p class="042abstractstekst">The aim of this study was to examine and describe genetic structure on autochthonous maize germplasm (flint types) from different localities in Kosovo using Hbr markers. The genetic characterization of 6-8 individual seedlings per each of 20 landraces was conducted by Hbr display calculated per selective base, the most efficient genetic diversity estimator to distinguish between landraces was primer combination Hbr-Int5-F/MseI+T. The strongest genetic relatedness (r = 55.57) had landrace ACC4 having orange colored seeds, showing the highest genetic uniformity when compared to other accessions. Clustering analysis using the Bayesian approach generated two genetic clusters for observed landraces. As a measure of population structure influenced by genetic drift and migration, Fst values for each genetic cluster were obtained. Higher Fst (0.4027) was calculated within the first genetic group comparing to the second one (0.2001), reflecting a higher levels of out-crossing and conservation between landraces from the first genetic cluster. A similar distribution of genetic linkages was observed from dendrogram, constructed using Dice coefficient and neighbour-joining (NJ) algorithm with minor deviations for landraces ACC6 and ACC28. Genotypes of ACCmk landrace reveal the highest genetic distinction compared to other genotypes, reflecting the highest number of bands (241) and the highest number of private bands (10) as the number of bands unique to a single population, respectively.</p>
