Six varieties of bread wheat and fifteen hybrids were used to calculate phenotypic and genotypic Correlation coefficient between each pairs of the following traits: grain yield, number of spike per plant, spike length , 100-grain weigh and number spike grain yield.

Path coefficient analysis was used to divide phenotypic and genotypic Correlation .

coefficients between grain yield and studied traits into direct and indirect effects.

The results revealed that spike length had higher phenotypic and genotypic Correlation with large direct effect on grain yield.
