Using (Partial Least Square) PLS Technic to Show the Genotype Environmente Interaction and its Effect on the Relationship Between yield Factors and the Other Factors in Barley Breeding Trails

Goal: The aim of this research is to use a new methods of statistics (PLS). This methods will be used to show that:
1- The genotype environment interaction.
2- How much the relationship between yield factors and other factors has been affected by the environment.
This technic will be applied in barley breeding trials.
