A field experiment was conducted at the Abu Ghraib Field Crops Research Station of the AgriculturalResearch Department for four seasons (autumn 2015, spring and autumn 2016 and spring 2017) to study thegenetic function controlling the inheritance of the yield and its components for yellow corn1 Season 1 Conductingone-way cross-fertilization between six strains of maize (MGW-48, ART-C-26, Dr-B-32, S-267, Pio-318, andDr-C-15) in the second method of Half Dialle for the first-generation embryos and in the spring and autumn 2016season In the autumn season 2017, a field comparison experiment involving the three generations' interactionswith parents was carried out in accordance with the design of the RCBD with three replicates1 The resultsshowed significant differences between F3, F2, F1 In all studied traits except for the weight of 1000 tablets, where the third generation by giving it the highest rates In all qualities except the weight of 1000 tablets1 Thehybrid ART-C-26 x S-267 gave it the highest rate in the third generation of the number of rows in the clovewas (18119) row and the grain yield in the area of (12119) tons / ha1 The results showed that all the traits gavea positive hybrid force except the number of ariens and the number of rows in the cloves gave positive andnegative hybrid strength1 The genetic analysis of the study showed that the average squares of the GCA in thefirst generation of the studied traits were significant except for the weight of (1000) tablets.

The ability of thespecial coalition (SCA) was significant for all the traits except for the weight of (1000) tablets.

The influenceof the general coalition was significant in most of the studied traits.

The father showed that (ART-C-26) had ahighly volatile and desired effect in most of the traits1 The effect of the special coalition in most characteristicswas that the degree of sovereignty only in grain yeild in all the attributes1 It was found that the inheritance ratioin the broad sense was high in all the traits except the weight of (1000) grains was medium and the inheritanceratio in the narrow sense was low in all traits except the number of It was mediocre1 The results show thathybridization is the most appropriate way to improve these traits.
