A field experiment was carried out at the Abu Ghraib Research Station during four seasons (autumn 2015, spring and autumn 2016 and spring 2017) to study the genetic function controlling the inheritance of morphological growth traits and determining the general and private coalition viability. The first season included one-way cross-fertilization of six strains of maize (MGW-48, ART-C-26, Dr-B-32, S-267, Pio-318 and Dr-C-15) in the Griffing (Half Diallel) method for first-generation hybrids, spring and autumn season, The first is to obtain second and third generation hybrids, The results showed that there were significant differences between the generations in the traits except the status of the product of each plant, where the superiority of the third generation by giving the highest rates in all attributes, except for the plant. Dr-B-32xDr-C-15, with the highest average height of the plant in the third generation, outperformed the ART-C-26xS-267 by giving it the highest rate in the third generation of the row number (8.19). The results showed that the positive hybrid strength of the traits except the number of rows in the mullet gave positive and negative hybrid strength. The hybrid (Dr-B-32 x MGW-48) gave the highest positive hybrid strength of 64018%. The genetic analysis showed that the average squares of the public and private coalition were significant. ART-C-26 showed a highly controversial effect that distinguished the DR-C-15 x MGW-48 hybrid by giving it the best effect of the special coalition. The rate of sovereignty was higher than one. The inheritance ratio in the broad sense was high and the inheritance ratio in the narrow sense was low.
