“…This useful heterosis ranged from (1.67% to 24.63%) and (4.54% to 21.42) in F1 and F2 generations, respectively. Significant heterosis was also found by Khilwat et al (2017), Fellahi et al (2017 and Ayoob (2020) For grain yield per plant, all hybrid combinations in F1 generation had significant useful heterotic effect which varied from 10.56% to 48.30% and 4.81% to 52.53% over the respective mid parent. thirteen hybrids has significant useful remain hetrotic effect which ranged from 11.92% to 51.45% over mid parents in F2 generation.…”

Six varieties of bread wheat were crossed in half diallel analysis. The fifteen F1's and their parents were evaluated. The experiment in a randomized complete block design with three replications at the Experimental farm, Faculty of Agriculture, Menoufia University Shebin El -Kom, Egypt during 2020/2021. The results cleared that genotypes, parents and the resultant fifteen crosses mean squares were found to be highly significant for all traits studied. Parent vs. crosses mean squares as an indication to average heterosis over all crosses were found to be highly significant for all traits studied. Variance of general combining ability was found to be highly significant for all traits studied. The parental variety Shandaweel-1 proved to be good general combiner for grain yield per spike and grain yield per plant. Also, Giza-171 was good general combiner in heading date, grain yield per spike. The most desirable SCA effects for grain yield per plant were detected by the seven hybrids i.e.

“…This experiment had 609 genotypes, comprising 20 F 4 -derived families and their 9 parents. The history of these families is that, after the initial crosses in 2010/11 [18], 30 F 2 lines were selected in each family by using pedigree method and were evaluated during the 2012/13 cropping season [19]. A total of 600 lines were planted and harvested in bulk during two consecutive growing seasons 2013/14 and 2014/15.…”

Three selection methods including direct and indirect selection along with selection index based on the phenotypic values of eleven traits of agronomic interest were assessed for their application in F4 bread wheat progenies. Significant genetic variation existed among parents and crosses for the traits measured. The following were the most efficient indices for simultaneous selection of superior lines for yield and its components: base index of Williams, followed by the sum of ranks index of Smith and Hazel. The selection-based index provided the highest grain yield gains as compared to the other selection criteria, except for flag leaf area, indicating that the direct and indirect monotrait selection were not appropriate in the situation analyzed in this work. PCA identified Ain Abid × Mahon-Demias, Ain Abid × Rmada, and Ain Abid × El-Wifak as the most promising populations. At 5% selection intensity, the top 30 lines selected were distinguished, in comparison with the standard check Hidhab, by significant improvements in yield and yield components.

“…Diallel analysis, used to estimate combining abilities in a set of parental lines and their crosses, has been recognized as the best breeding strategy for genetic understanding of important traits in the populations of interest [19]. The parents with significant general combining ability (GCA) for FHB resistance have been identified as good donors of average and/or high FHB resistance to their progeny [16], leading to the high relative importance of additive genotypic variance effects in FHB resistance response [20].…”

Breeding resistant wheat cultivars to Fusarium head blight (FHB), caused by Fusarium spp., is the best method for controlling the disease. The aim of this study was to estimate general combining ability (GCA) and specific combining ability (SCA) for FHB resistance in a set of eight genetically diverse winter wheat cultivars to identify potential donors of FHB resistance for crossing. FHB resistance of parents and F1 crosses produced by the half diallel scheme was evaluated under the conditions of artificial inoculation with F. graminearum and natural infection. Four FHB related traits were assessed: visual rating index (VRI), Fusarium damaged kernels (FDK), and deoxynivalenol and zearalenone content in the harvested grain samples. Significant GCA effects for FHB resistance were observed for the parental cultivars with high FHB resistance for all studied FHB resistance related traits. The significant SCA and mid-parent heterosis effects for FHB resistance were rare under both artificial inoculation and natural infection conditions and involved crosses between parents with low FHB resistance. A significant negative correlation between grain yield under natural conditions and VRI (r = −0.43) and FDK (r = −0.47) under conditions of artificial inoculation was observed in the set of the studied F1 crosses. Some crosses showed high yield and high FHB resistance, indicating that breeding of FHB resistant genotypes could be performed without yield penalty. These crosses involved resistant cultivars with significant GCA effects for FHB resistance indicating that that they could be used as good donors of FHB resistance.
