Abstract
improving seed yield in a segregating population of faba bean (Giza 429 × Triple white × Misr 1) × (ILB-938 × Nubariah 1 × Misr 1) in the  F2- F5 generations. The experiments were conducted at South Valley University Experimental Farm, Qena, Egypt during growing seasons 2014/2015 to 2017/2018. Highly significant differences among the F5-selected families were observed for the selection criterion; seed yield/plant and all correlated traits either after three cycles of selection (pedigree method) or one cycle selection (bulk method). The genetic variability retained after bulk method was larger and more pronounced than that after pedigree method for the selection criterion; seed yield/plant. While, all studied correlated traits showed smaller genotypic variability after bulk method than that after pedigree method. After three cycles of selection, pedigree selection increased seed yield/plant by 21.82, 20.58 and 53.49% from the bulk sample, the best parent and the check cultivar, respectively. But, after one cycle of selection, bulk method increased seed yield/plant by 8.43, 7.27 and 38.24% from the bulk sample, the best parent and the check cultivar, respectively. Pedigree selection method for improving seed yield was more efficient compared to the bulk method in isolating high yielding genotypes. However, it was accompanied with favorable increased in no. of branches/plant, no. of pods/plant, no. of seeds/plant and 100-seed weight and undesirable delay in flowering date.
