Abstract
Used in this study six varieties(parents) of wheat bread are (Aba 95, Al-Rasheed, Abu Ghraib, Jihan, Tammuz 2, and addna), the heating of the individual for the second part of the number (15) hybrid, planted varieties parental six glare they exchange the mid-term research station, Department of field crops of the Faculty of Agriculture, University of Tikrit, in the second week of November (2021), and using randomized block design full (RCBD) with three replications, and examined the act genetic competence of the Union of the page: The number of panicles plant and number of grains for weight of 1000 grains and plant individual and continue to biological and manual harvest, and summarize the most important results are the following: that the act gene sovereign was the most influential of the act gene overtime and contrast genetic top of biodiversity loss studied all of them, the heritability in the broad sense of high tension event in the narrow sense of state and the degree of sovereignty is greater than one (super) All traits under study, and the proportion of the components of the exchange provided the federal public to the ratio of the components of the exchange provided to the federal special was less than correct all the page under study, the best parents, spectators and the effect of positive and desirable for the federal public is the parent (1) and paste the quotient of the individual plant guide to harvesting, and the parent (3) and paste the number of ears plant and number of grains for weight of 1000 grains, the higher the value of the positive impact of the decision of the federal hybrid (1 x 4) for number of grains per spike and weight of 1000 grains and plant individual and continue to biological, hybrid (2×3) The page number of panicles per plant and number of grains per spike and weight of 1000 grains and continue to biological, hybrid (2×4) for number of grains per spike and weight of 1000 grains and plant individual and continue to biological guide to get. Parents superior in general Union ability with a high phenotypic significance can be introduced into wheat breeding programs to produce hybrids superior in special union ability that can be invested in the next generations within breeding programs.
Key words: bread wheat, cross-hybridization, federal ability, genetic action.
