| Summary, etc. | The genetic materials were F2, F3, F4 and F5 generations of the cross “Giza164/Sids4” of bread wheat. <br/>The experiments were conducted under drought stress and normal irrigation. Three cycles of single trait selection <br/>for grain yield/plant (GY/P) and five models of desired gain selection index (combinations from seven traits) <br/>were achieved in both environments separately. After the third cycle of selection, the selected families for <br/>the six types of selection under drought stress, and the selected families under normal irrigation were <br/>evaluated under both environments. The GCV in GY/P decreased from the F2 to the F5. The remained variability <br/>in GY/P for the five selection indices was higher after the three cycles of selection than the single trait <br/>selection for GY/P. Heritability estimates as calculated from regression of F5/F4 generations for the traits <br/>under selection pressure were higher under drought stress than under normal irrigation except few cases. <br/>The observed gain increased from index1 to index5, and all indices were better in improving GY/ P than direct <br/>selection for GY/P. It could be concluded that selection index was better in improving grain yield than single <br/>trait selection for GY/P. Furthermore, selection under drought stress (antagonistic selection) in these materials <br/>was better than selection under normal irrigation (synergistic selection) in improving GY/P either selection <br/>evaluated under drought stress or under normal irrigation. Selection index5 which involved GY/P, 100GW and NG/S <br/>was the best index in improving GY/P.<br/>Keywords: Triticum aestivum, Drought stress, Selection index, Realized heritability, Observed genetic gain.<br/> |
