“…the high values of the general coalition effect of a particular parent mean a high host variance for this parent, which allows the possibility of transferring the trait from him to many of his crosses, and the low value indicates the weakness of his host variance and thus it is possible to transfer the trait to him from other parents. These results are in agreement with what was found by Mahmoud and EL-Eslamboly (2014); Saval and Patel (2017); Hamdi (2022) in their study on the tomato plant. The effect of the special ability on the union is shown in Table 3 the effect of the special ability on the union of individual crosses for all the traits studied.…”

“…It was found through the results that the hybrids with a special general coalition effect (in the desired direction) resulted either from two parents who have a good general coalition effect, or from two parents, one of whom is good in the general coalition and the other is weak, or from two weak parents in the general coalition, and this indicates the possibility of benefiting from the pure lines of all tomatoes with its effects Different general coalitions to produce distinct hybrids. These results are in agreement with what was found by Al-Mfargy and Al-Douri (2015), Mishra et al (2020), andHamdi (2022).…”

The study aimed to show the best effect of the general combining ability (GCA) and specific combining ability (SCA) for parents and their hybrids of the studied traits. The study included two main successive seasons. In the first season, cherry tomato pure lines were selected that were introduced from the Tomato Genetics Resource Center (TGRC) at University of California, Davis in USA, 5 pure lines were selected which were the most genetically Distant which are (LA4451, LA4753, LA3334, LA1221 and LA4689) and its code (1, 2, 3, 4 and 5) respectively and entered into Full Diallel crossing program to produce individual crosses. The second season included an experiment to compare genotypes (5 parents + 20 cross-hybrids. and its reciprocal hybrids) according to RCBD design with three replications. The results were as follows: parents 1 showed a general significant ability to combine in the desired direction in terms of fruit set percentage and fruit weight, while the superiority of parent 4 in terms of plant yield and total yield. The parent 5 was superior in the number of flowers in the inflorescence, the number of total flowers of the plant and the number of fruits, whereas the hybrid (5×1) showed superiority in the number of flowers in the inflorescence 35.667, number of total flowers 259.66, the percentage of the set 15.69 and the number of fruits 86.83. (1×4) appeared significant effect of (SCA) were shown significant and desirable in the traits average fruit weight 1.47, plant yield 0.55 and total yield 0.69.

“…For grain yield, the dominance genetic components were greater than additive ones and revealed the predominance of nonadditive gene action for the inheritance of said trait in both generations. Zare-Kohan and Heidari (2012) reported larger values of dominance genetic components than additive ones for grain yield in spring wheat; however, Mohammadi et al (2007) and Allah et al (2010) reported findings where the average degree of dominance was less than unity and proposed the additive type of gene action for grain yield in wheat. Graphical diallel analysis showed the additive type of gene action for grain yield in spring wheat (Farooq et al 2011).…”

A half-diallel mating system was used to evaluate six wheat cultivars and their F 1 and F 2 populations for inheritance of earliness and morphological and yield traits. These genotypes were crossed in a half-diallel fashion during 2010-2011 to get 15 cross combinations. The 6 × 6 wheat F 1 and F 2 half-diallel populations and their parental cultivars were assessed in a randomized complete block design during 2011-2012 and 2012-2013, respectively. Genotypes revealed significant (P ≤ 0.01) differences for all the traits in both generations. According to scaling tests, an additive-dominance model was partially adequate for all the traits in the F 1 and F 2 generations. Diallel analysis revealed significant values for additive (D) and dominance (H 1 and H 2) genetic components of variance for majority traits in both generations, however, the overdominance type of gene action was predominant for inheritance. Additive gene action was observed for days to heading and plant height in the F 1 generation and tiller per plant and grain yield per plant in the F 2 generation. In the loci (H 2 < H 1), the majority of the traits showed an unequal proportion of positive and negative genes with asymmetrical distribution among parental genotypes (H 2 /4H 1 < 0.25). Significance of both additive and nonadditive genetic variations suggested integrated breeding strategies with delayed selection for improvement in wheat populations.

“…Evaluation each of genotypic variation coefficient and heritability give the breeders a better idea about selection date. From table (5), heritability values were high to all traits except to spike length (33.49%) and Grain yield per plant (57.74%) were medium . Results agree with [14].…”

The research was carried out to study some of genetic parameters for individual hybrid (ACSAD 1115 × Bohouth6) of soft wheat as (days to heading, plant height, peduncle length, spike length, grains per spike, grain yield in individual plant) using an analysis of generations not segregate and second segregate-generation. It was conducted at the Agricultural Research Center in Hamah per to the randomized complete block design (RCBD) in three replications, during two growing seasons. Four genetic populations (P 1 ,P 2 ,F 1 ,F 2) of this hybrid were used. Results showed that act of the overdominance was controlling on the behavior of the trait (spike length), while behavior of rest of the traits was affected by the partial dominance. The results concluded that significant value of heterosis compared to the average of the parents, for trait grain yield per plant in the first generation F1 was with non-significant inbreeding depression in the second-generation F2. High heritability in a broad sence associated with a high genetic advance in traits as (plant height, grains per spike), which refers to the possibility of improving these traits through selection in the early generations.While rest of the trait (days to heading, peduncle spike, spike length, grain yield per plant) can be improved through repeated selection in the late segregate generations.
