الملخص الإنجليزي

A total of 608 eggs from 304 dams (100 F1, 54 selected dams and 150 F2, with 2 replicates for each dam), were tested to estimate the selection differential, response to selection, phenotypic correlation coefficients heritability and genetic correlation between egg traits including external and internal egg qualities.

Results showed that there were a highly significant differences (P≤0.01) among F1, selected parent (SP) and F2 generation for egg weight (EW), shell weight (ShW), shell thickness (ShT), albumen weight (AW), albumen height (AH), albumen diameter (AD), Haugh unit (HU), yolk weight (YW), yolk height (YH) and yolk diameter (YD).

The highest heritability estimation recorded for Haugh unit (0.49), while the lowest one was recorded for AW (0.12).

The highest genetic correlation coefficient recorded between EW and AW (0.56), while the lowest one was found between EW and AH (-0.02).
