Abstract:\u00a0<\/strong><\/span><\/p>\n

This study carried out in Humaimeh Research Station\/ Aleppo Center for Scientific Agricultural Research\/Syria during seasons 2019\/2020, and 2020\/2021 to estimate the components of genetic variation and study the genetic action of Crop Parameters and its components using Generation Mean Analysis Model, F1, F2, with their parents and BC1 & BC2 were selected from MSc thesis according to T- test. The results showed that averages of generations were high significant for all parameters in all hybrids. The results indicated to the importance of additive effect and dominant genetic action which varied between parameters in all hybrids. The dominance x dominance interaction was more effect of the additional genetic action x additional, and the additional x dominant in all the traits studied. The values of phenotypic variance coefficient were higher than the genetic variance coefficient in all the traits studied, which indicates that the traits were influenced by the environment, and the genetic variance coefficient was higher than the environmental variance. The highest values of predicted genetic progress were associated with high and medium values of the degree of heritability in the narrow sense for the traits studied. The results showed the possibility of selection in the early segregation generations, especially the first and fourth hybrids, for the traits of early maturity and 1000 grain -weight. Therefore, these hybrids can be introduced into a breeding program to benefit from them in improving these traits in barley under drought conditions<\/span><\/p>\n
