| Abstract | ||||
| This study was carried out at the experimental farm of the Faculty of Agriculture, Al-Azhar University, Assiut branch during three successive winter seasons of 2020/2021, 2021/2022 and 2022/2023 to improve some yield components of faba bean. The breeding materials used in this experiment were the F2, F3 and F4 generations of one cross (Giza 843 x Misr 3). Pedigree (SP) and single-seed descent (SSD) selection methods were used for days to maturity, number of branches/plant, number of pods/plant, seeds yield/plant and 100 seed weight to study phenotypic (PCV) and Genotypic (GCV) coefficients of variability, expected gain from selection (EGS) and realized gain from selection (RGS). Results indicated that PCV and GCV estimates decreased in sequence generations. EGS and RGS estimates were useful and decreased from generation to generation in most study traits. The EGS% for PS and SSD in F2 for seed yield/plant was 7.12 and 8.20, respectively, and diseased to 7.11; 8.16 and 6.76; 7.14% in the F3 and F4 generations, respectively. The realized gains for selection (RGS %) in PS and SSD were 24.77, 24.27 and 20.43, and 21.35% in the F3 and F4 generations, respectively.It was found that pedigree and single-seed decent selection methods have good efficiency in the selection procedures to improve the studied characters. | ||||
