Title : Estimaion GCA and SCA, hybrid potency, protein gene action and grain yield for two generations of bread wheat grains ( Triticum aestivum. L)

Abstract:

The aim is to study the federative potential, the strength of the hybrid and the genetic action of some traits related to the quality and quality of the grains of genotypes of bread wheat genotype (Triticum aestivum L.)) which are Adana, Cowes, July 2, Site Mall, Research 22, Rashid, Milan, Sham 6, Aba 99 and Abu Ghraib. Half cross hybridization to obtain (45) hybrids, then these hybrids were planted with parents in three replications using RCBD design for the first generation 2018 and 2019 and the second generation 2019, traits (individual plant yield and protein ratio) were studied. Parents, hybrids, and fathers against hybrids) the genotypes and fathers in addition to hybrids were significant at a probability level (1%) for all traits, while fathers against hybrids were not significant for the individual plant yield trait for all generations and the second generation 2019 for the protein ratio and the first generation 2019 for the total protein ratio and the significant in For other generations of the protein ratio trait, and that the ratio between the components of the federal to the special assessment was less than the correct one for the individual plant yield trait and for all generations and the first generation 2018 for the ratio of protein and the next generation The first and second 2019 for protein ratio and meta-analysis, and this indicates the importance of additional and non-additive effects on the studied traits. Parents 4, 7 and 9 outperformed with general federal ability for most of the traits. The hybrids were (1 × 8), (6 × 9) and (7 × 10). ) And (8 × 10), (2 × 6) and (2 × 10) have a special federal ability for most of the traits.
