| Abstract | ||
| The present study was carried out at two locations, i.e., Sakha and Mallawy Agricultural Research Stations, within two successive summer seasons (2022 and 2023), to evaluate four soybean genotypes (Giza22, H1L3, H4L4 and Giza111) under three different sowing dates (first of May, Mid of May, first of June). GGE model pattern analysis was used to determine the best genotypes for seed yield and its components. To identify the best genetic architecture and the most important features in the yield trait, Genotype by Yield*Trait (GY*T) analysis was also conducted using the GGE model. The results revealed notable variations among the criteria under investigation. The optimal date for yield and its components was determined to be the first planting date. The genotypes (Giza 22, H1L3) recorded the highest values for physiological traits and yield respectively. | ||
