Hybrid vigour is one of the most important phenomena became in practice all over the world for its higher performance in maize and several other genera of crops, vegetables, and fruit crops. There is no single theory explains this phenomenon. The only general rule known about having hybrid vigour is that crossing between two genetically diversed inbreds. Epigenomics is thought to be involved in hybrid vigour. However, exact timing of maternal and paternal genomes after fertilization of the endosperm is still not totally understood. It is still believed that the ratio of maternal to paternal gene expression through endosperm development is 2m:1p. The diverged methylation level of the crossed inbreds could be involved in hybrids of

This research was aimed to identify the most important factors affecting the production of wheat crop in Iraq for the period 1990-2016. The ARDL model was used to interpret the relationship between the dependent variable and the independent variables in the search. The research concluded that the continuous increases in the population would lead to increases in support to the wheat crop due to the increase in consumer demand for this crop, which prompts the state to try to encourage producers to achieve increases in production. The research also found that increases in inflation led to higher levels of support because rising inflation rates unfairly distribute income among individuals, therefore the government is
