Abstract
The present study was carried out at the Experimental Research Farm of the Faculty of Agriculture, Sohag University at El-Kawthar Town, Sohag Governorate, Egypt during the 2022 and 2023 summer growing seasons.  The breeding material used in this study were F2 and F3 families from one cross of sorghum, i.e., Dorado × Giza-15 (pop.). The objectives were to assess the relative efficiency of selection methods for improving grain yield/ plant and correlated traits. Highly significant differences among F2 and F3 families satisfactory genotypic coefficient of variability and large magnitude of broad sense heritability were obtained for all studied traits. In two generations, grain yield/plant showed positive highly significant correlations with all studied traits. The results showed high genetic advance as a percentage of the mean (GAM %) for all studied traits in the two generations (F2 and F3) except for days to 50% flowering which was moderate. Direct selection for grain yield/ plant increased by 19.74 % from the bulk sample after one cycle of selection. This increase was accompanied by an increase in plant height (3.41%) and 1000–grain weight (18.90%), a favorable decrease in days to 50 % flowering (-0.81 %). The best-given family after one cycle of selection was Family No. 50 which out-yielded the bulk sample by 82.15% for grain yield/plant and by 52.15% for 1000 grain-weight.
