“…Nonetheless, Baloch (2004) reported that both additive and non-additive gene actions are involved in controlling seedcotton yield and yield contributing traits are controlled by additive gene actions. Such information support the evidences behind the inheritance that both additive and non-additive gene actions are responsible in controlling the traits pertaining of yield and its factors during cotton breeding (Mühleisen et al, 2013;Klykov et al, 2018).…”

“…Conversely, the better performance of hybrids is studied by SCA (specific combining ability) (Madić et al, 2014). The specific trait studied in hybrids through SCA is controlled by the non-additive gene (Acquaah, 2012;Klykov et al, 2018). A successful plant breeding program based on the estimation of combining ability which driven by genes actions (Panhwar et al, 2008) Various mating designs have been described and compared in many research investigations (Kearsey and Pooni, 1996;Hallauer et al, 2010;Acquaah, 2012).…”

General and specificcombining ability areone of the important plant breeding tools used to compare performances of lines in F1 populationacrossgrowthand yield contributingtraits. Theexperiment was carried out in2014 under the agro-ecological condition of Tandojam, Sindh Pakistan based on a randomized complete block design with four replications. Six parentsand their crosses (nine hybrids), in whichthree femaleparents as lines (Bt-008, IR-1525,and neelam-131) and three male parents as testers (NIA Sadori, NIA Ufaq and NIA Perkh) were evaluated in the study.In F1generation,the meansquares for combining ability for targetedcharacteristicsdisplayed highly significant(p<0.01)generalcombiningabilityeffects in lines for all traits except lint index. But in the case of testers, the GCA effects were significant for sympodial branches plant-1, seed index,and seed cottonyield plant-1and highly significant only for monopodial branches plant-1, ginning outturn%, staple length. While, mean squares values for the interaction of line x tester revealed highly significant specific combing abilityeffects for plant height, monopodial branchesplant-1, bollweight,and GOT%. The two parents Neelam-131 and NIA Ufaq manifested higher general combining ability effects and were good general combiners for yield and yield components and can make a potential material for varietal seed development. Foryield contributingcharacters, crossesIR-1525 ×NIA Ufaq and IR-1525 ×Perkh showed significant SCA effects among the rest of the crosses. Fromthis study, it is suggested that crosses exhibiting greaterSCA valueand parents indicating good GCA valuemust be chosen for enhancementof a specific trait

“…The SCA, specific combining ability, makes it possible to select the best favorable alleles (Madić et al., 2014) when a hybrid combines well only in certain crosses, which means that it has a good SCA (Qu et al., 2012). In a F1 generation, the study of agronomic parameters as well as grain yield is very important for the analysis of genetic determinism of hybrids (Zhang et al., 2013) the mode of action of genes provides information on the forms of transgression of characters (Klykov et al., 2018), indeed, the mode of action of genes in F1 hybrids is classified as having an additive and non-additive expression, the additive gene expression is where the level of gene expression of F1 hybrids is equal to the level of gene expression of the average parent. On the other hand, non-additive gene expression occurs when the level of gene expression in F1 hybrids is different from the average parent (Fujimoto et al., 2018).…”

An experimental trial was carried out during two successive crop years, (2015/2016 and 2016/2017). The study focused on an F1 generation of barley (Hordeum vulgare L.), composed of twenty hybrids, from a complete diallel cross between autochthones and introduced cultivars.The aim is to bring together in one combination the maximum of favorable genes existing in local and introduced genotypes. The evaluation of the genetic determinism of parental lines and their descendants, through the measurement of six quantitative variables, is ensured thanks to a detailed genetic analysis according to the model of Griffing (1956) and confirmed by the graphic model of Hayman (1954).The results obtained reveal the existence of a great genetic variability between the hybrids and between their parents; additive and non-additive genetic effects are involved in the control of the variables evaluated. The variance ratio of general combining ability (GCA) and the specific combining ability (SCA) is less than one unit which explains the preponderance of the dominant genes, with a super dominance involved in the expression of the length of the spike, the number of grains per spike and the productivity per plant; on the other hand, complete and partial dominance respectively control the expression of the height of the plants and the weight of one thousand grains.

The current paper has presented the analysis results of the value of heterosis and the degree of phenotypic dominance of hybrids F1 obtained by saturating crossings of two-row and multi-row spring barley forms. The purpose of the study was to determine the value of heterosis and the degree of phenotypic dominance of the main quantitative traits of the multi-row hybrids of spring barley. The study was carried out in the laboratory for grain crops and groats breeding of the FSBSI FRC of Agrobiotechnologies of the Far East named after A. K. Chayka. There were studied 68 varieties of multi-row spring barley forms selected from the world collection of IPI of various ecological and geographical origin. The two-row varieties ‘Primorsky 98’, ‘Primorsky 44’, ‘Primorsky 89’, ‘Tikhookeansky’ and ‘Vostochny’ developed by FSBSI FRC of Agrobiotechnologies of the Far East named after A. K. Chayka were taken as maternal forms. Four multi-row barley varieties ‘Kazminsky’ (Khabarovsk Territory), ‘Peguis’ (Canada), ‘Kolchan’ (Altai Territory), ‘07N1’ (China) with valuable economic traits were taken as a paternal form. There was conducted a five-fold backcrossing of hybrids with paternal forms and there were selected the populations of multi-row genotypes. The most of the hybrids F1 manifested their heterosis simultaneously according to four traits, productive tillering, number of grains per main head, grain weight per main head, and grain weight per a plant. Only two hybrids ‘Primorsky 98 x Kolchan’ and ‘Primorsky 89 x Peguis’ showed a depression. There was identified heterosis by the traits ‘number of grains per main head’, ‘grain weight per main head’ in all hybrids. When analyzing the inheritance of the trait ‘grain weight per a plant’, there was established overdominance of this trait at the highest values of the hybrids ‘Tikhookeansky x Peguis’ (9.7) and ‘Primorsky 44 x 07N1’ (5.2), the heterosis degree was 50.4% and 82.2%, respectively. There has been established that three hybrids ‘Primorsky 98 x 07N1’, ‘Primorsky 44 x 07N1’, ‘Tikhookeansky x Peguis’ can belong to the most promising ones.
